    First focal plane for stalking?

    I think this is one of those topics that divides people depending on their personal preferences, so not sure how much help this is really but... The rifle I use for stalking has a Kahles ffp on it. In reality its mainly used on the range (UKD) with some shots at deer. Stalking is split between woodland and hill. Most of the hill stalking is hind culling. So up the hill, it is great. I can set the mag to give me a decent field of view and the reticle is still correct. That matters as I hold for the wind and for follow up shots I can make some fast but small adjustments if the deer run a bit further out. The fov is important so I don't have to come off the rifle for the next shot. The fact the reticle is always true lets me shoot a bit more dynamically on the subsequent shots and I don't have to be at 22x or whatever if I am going to use the reticle at all. In the wood though that's a bit of a waste of time. Ranges are not far enough to worry about those sorts of adjustments, wind is largely irrelevant and to get the FOV right, it is dialled right down almost to a cross. This is why some people HATE ffp. Personally I don't really care as they are so close a cross is all I need. In some ways that is what the reticle is 'telling' me. On the Kahles the thickness is fine, the trade off is it is a bit chunky at 25x but most of the time I am in the teens and if I am at 25x then the centre dot is ideal. I have a mate who is a professional stalker who detests FFP and is happy with the idea of memorising reticle sub tension values at full and half power. In return he gets a consistent reticle at all magnifications. For me this is an accident waiting to happen as I have forgotten where the magnification is set on my NXS on the range before and it takes a while for me to realise why I am missing. I am sure I could manage this if I was a bit more diligent in my drills as I assume he is. Kills too many deer not to be. For me, my view is that I don't need a scope in the woods at all and in fact they are a hinderance for close shots. A good red dot will do the job out to 150 certainly and with a little bit of shooting 200, calibre dependent I suppose. But that wasn't the question....
  5. Magnetos are quite sensitive to how close they are to the bullet on exiting the muzzle. Nobody wants to shoot it but you have to set it up quite close to reliably register shots. Its a one time fiddle as once you know the proper set up you just use the same bits and you are good to go. I had 2 Chorny's. Far too fiddly, never entirely sure the results were right and I shot them both. Had I not bought a magneto I would have used a bullet with a Litz bc, measured drop at say 400 and fiddled with JBM to derive the mv. I have to verify/tune anyway, so not sure it would be much of an imposition. I can reload a lot of ammo for £300. Its handy though.

    Browning x bolt.

    Not really. If you have definite features/performance in mind it is easy. The majority of production rifles have features which are more about cost than function and if you don't want to accept that then there is a bit of a hunt for a rifle that does not compromise in areas that you deem important. Combine that with calibre choice and off you go.

    1st shot in a string velocity

    Because if the trend of a fast first shot shows up on both instruments then it is a reasonable assumption that this it is a real phenomenon even if the absolute velocity values on the two instruments are different. If the trend on the first shot does not show up on both then this increases the probability that the trend is itself suspect. Given this is an unusual phenomenon it would then be reasonable to be a bit suspicious of the data from the Labradar. Occams razor. It could just be a statistical anomaly of course in which case shooting a heap of groups would see it disappear

    1st shot in a string velocity

    Verify the instrumentation Borrow a magneto speed. Fire with both magnetospeed and labradar at the same time. See if the trend persists

    Powder Temp v MV

    If we are getting pedantic we don't really know what the inputs were (ammunition and chamber temps) to associate with the output i.e. mv measurements. We have some qualitative input data and quantitive output data but only a minor change. So usual stuff: How large were the sample sizes? Is the data correct but just represents a different sample from the ammunition batch. In other words are the sample sizes large enough to highlight a statistically significant change in velocity. If not then maybe you should just average the numbers. In reality it is probably not valid unless you were unusual in the shooting world and shot a really large sample. Nobody else seems to. 21 C and 25 C are not big shifts so can the velocity effects be measured accurately or are other effects interfering. I take measurements when it is 'cold' and when it is 'hot'. You will get a more representative result. Really you want to take measurements at the high and the low, then you can be reasonably sure it is accurate between the two, the further you get outside those limits the less certain you can be it is correct? To be really pedantic, you see some of the guys in videos from the US using a thermal temperature instrument to measure ammunition AND chamber temperature. So you would have control over the input therefore be better able to interpret the trend (or lack of). Life is too short...
  12. yes you did say that twice. So what ? Are you implying that it has no effect on the hearing of the people close to you ?
  13. They REALLY annoy the guy next to you. "The blast from a muzzle brake isn’t noticeable to the shooter" - not so sure about that one, maybe it depends on the brake ? How about using a can? No annoyance and some recoil reduction. Not as effective as a brake granted, but still good IMO.
  14. Happened to look at this last night. According to Quickload my 308 load in a 20" barrel has a residual 8 kpsi while a 7 SAUM was about 12 kpsi in a 25". Not quite sure how that relates to what the mod experiences...
  15. I see what you are saying and why but I don't think I would be betting my house on it. The chatter is exactly that, chatter; and the study does not look statistically valid. To be fair to the guys that did it, they actually say that themselves in their comments about sample size. Looking at the standard deviations and the changes in velocity, they are so similar at the longer barrel lengths that you could prove anything you wanted. Some of the numbers also just look odd which demonstrates the problem. As the numbers don't go beyond 30" and are dubious close to that value, I don't see how anyone can make any informed comment at all never mind a definitive statement. Still it is better than nothing? Maybe not. The other point in the thread in general I don't really get is the apparent belief that once the powder is burnt then any extra barrel is a waste. Well if the bullet still had 30 kpsi or whatever up its chuff it is still going to accelerate so the extra inches are worth while ? I have not run quickload on this cartridge but on others that I have the powder burn often finishes well down the barrel and the residual pressure adds a lot to the final muzzle velocity

    How do You prep Your brass? UKV survey.

    Wipe. Junk/check anything I don't like the look of - don't waste time on a duff case. De-prime Brush inside neck and primer pocket Body resize Neck resize Cordless drill - trim, debur chamfer + run up and down the case a couple of times with steel wool - cheapskate trim and clean process 100% - Simple visual check. 100% - NoGo bullet hand seating test - check neck is sized/I have not screwed up again etc etc Sample check - concentricity gauge - QC to ensure process is giving desired results not producing junk Store/Junk/Rework/Time to Anneal? ....
  17. There isn't one gun or calibre that will do all of that 'well'. Its a well trod path with no agreed answer. Some thoughts though... None of the rounds you mention are a good compromise for that list (IMHO, others will differ i am sure). Do some googling and see what the common rounds people use for each of your areas of interest. Long range target seems to split into a couple of broad groupings - 6.5's for long barrel life or 7mm WSM etc for best performance but high demands on the wallet for replacement barrels. 284 Win somewhere in the middle ? 300 Win Mag is 'unloved' (?) with many due to its belt complicating reloading - one of the reasons for WSM's and SAUMS. Large UK deer. I hump a varmint rifle up the Cairngorms in 308 but my AI would be beyond the pale. Fine off the bonnet or for sitting in a bush though. If you are looking at recreational stalking any of your 3 calibres would be fine. As a minimum IMO you are looking at 2 rifles - target + hunting. To try and be helpful rather than just being a smart ass, some ideas -> 1. Target - buy an accuracy international AT or similar with a 6.5 barrel for target - cheap to shoot, as good as a custom (arguably better); has quick change barrel so very flexible; the 6.5 will perform well enough but not beat you up. Its not stupid money and is an excellent product. 2. Hunting - 30-06 minimum; custom (if you want) built along the lines of the Mauser 03 with a semi weight barrel (#5 or so)

    Foxes. What do you do with them?

    😀 how did I get 'in' then ??? There is a guy in Cornwall that eats them - but normally limited himself to assorted roadkill. Keeps 'em in a freezer. Gets a lot in as much of it is 2 - dimensional. There was a documentary on him a few years back, the wife refused to be seen on camera for some reason. The biggest shock was that he had a wife...

    Bump shoulder back

    Depends what you are doing. Why not resize it every time and have a constant load ? Seems like a plan. There was a view once upon a time that best accuracy was achieved by neck sizing only, but that seems to have been debunked. Overworking the brass is one common reason for not fully resizing the brass. Is that really a problem? Views differ. SO - I use Redding body dies. Nowt to adjust really. Set it up square and away you go. Works fine. IF - you want to be a bit more precise/techhy then you can get some shell holders from Redding (+others?) that control how much you bump the shoulder back. 2 thou bump is a popular number for some reason. I suppose it gives a consistent minimum amount of squeeze so you get a consistent minimum resized round. I suspect there is a way you can adjust the die to achieve the same thing but without the small expense, can't remember how. Basically I have the kit but don't bother with it. I fl resize with a body die and then resize the neck. The AI will do 0.25 moa consistently without coal tuning so its not a terrible practice. Rather not risk failing to load a round

    Elcho powders

    I still have some Elcho 17. I have used it most in my 308, it is my go to powder. It works well with heavier bullets, I have had good results with 180 - 208gr. Wasted on lighter bullets really i.e. no appreciable performance gain, but they still go bang. I would expect you to find yourself filling the case/compress the load with the heavies if you are loading for velocity. Reloader 17 data is equivalent as it is the same powder. My current tub does not seem to produce the same energy levels as previous tubs, if you have a crony it is worth checking the assumption that it is "the same as X". It is also somewhat temp sensitive. I don't have precise numbers but stiff loads designed for normal weather gave a decidedly stiff bolt on a hot summers day. Again if that matters, it is worthwhile collecting some temp vs velocity numbers.

    IOR problems?

    1. It was ever thus. Why is/was Schmidt so popular? Military and Police contract so 'it must be the best' ?? 2. Absolutely. I managed to get a look though several of the big brand scopes side by side at a shooting show and spent a fun wee while switching back and forward. My unscientific conclusion? I could not tell the difference between the top of the line scopes optically. In reality that means nowt, but its my eyes looking through it. While the PRS thing may have been sponsored (he is just a regular Joe so how is he going to fund it?) it seems to be the only comprehensive study that has applied methodical testing so gives us some data to make a judgement on. The biggest flaw, IMO, isn't that the testing is sponsored by Vortex but he only tested one of each scope so how can we rely on their conclusions as to mechanical (or indeed optical) performance? If it was my scope being tested I would make sure I sent them a damn good one. So perhaps it is at best a measure of how well it can perform. Who knows?

    Home Office FOI Request

    After a bit of being grumpy about a post relating to the FCSA, I made a freedom of information request of the Home Office to get data on firearms offences. I tried to find it online but it was hard to track down. Turns out there is a pile of data available from ONS, I just could not find it. I got a good response from the Home Office considering I asked for a breakdown of the data by all sorts of things mainly just to make sure I got what they had. The data relates to England and Wales. They also provided me with a bunch of historical data. If somebody wants the historical data PM me or look here. Its not 'published' yet, but will make its way there in due course. However this link takes you to the best data in the form of a downloadable Excel spreadsheet detailing offences involving weapons. Lots of tables, data cut lots of different ways. Hours of endless fun. A lot of the data supports the views we already have but at least the various organisations could use this to provide some evidence to support our arguments. A taster: Rifles 9600 offences involving 'firearms' in '2017' of which 61 involved rifles fired 30 times 10 people injured including 1 fatality So the only firearms action the govt is planning relates to rifles when there were 2685 handgun and 28 machine gun offences in 2017. Where do they think the terrorist is likely to look for his firepower? FCSA, let me know the answer you get. Areas of risk: 1. London 2. West Midlands 3. Northamptonshire (?!) Age groups of victims: 10-19: 20% 20-29: 30% 30-39:20%

    Home Office FOI Request

    Yes that was the obvious argument to me. It's all very well grandstanding by passing laws that deal with theoretical risks, nice politics, but how about doing something to defend the populace by tacking a problem that really exists and has meaningful consequences i.e. the handgun offences. There is already legislation in place that does not seem to be protecting the population so what are they going to do about that rather than attacking law abiding citizens, and if that law does not work (demonstrably) why should they bother with another one that they presumably will not bother to enforce either. Now the data is out there (it always was just hard to find) why are the FSCA, BASC, NRA etc not upping the ante and attacking the Home Offices performance and strategy? F*cking useless bunch of old bufton tuftons that's why.
  24. Mods - what's a 'good' mod? Takes your pick, I suspect. SL5 is popular as it is a compromise between price, size, weight and life. So probably not best at any of them! Bergara vs Howa vs Tikka. Depends on the model and your app so that one is too hard. I have a semi custom Howa - very good but its a semi custom so costs from 'smithing. Tikkas I have known shoot well but stocks and mags are suspect so model selection is important - HOWEVER easy to trick up GRS Berserk, AI style bolt knobs just to swap in, aics bottom metal available. Bergera have 3 barrel profiles across the models, aics poss out the box, as is adj stock. Kind of have to make your own mind up on the compromises...
  25. Not sure I really want to ask this, but can't resist... Do they really do this ? I don't think they do it up here ? Waste of time, how is ground safe for 222 but not 308 ??
