    AI AT barrel weight

    Well its 20% shorter so as a maximum 20% less weight. So about 410gr, bit less because of taper Or more usefully - the rifle will go from 14.3 lbs to 13.4 lbs. A 6% reduction.

    .243 load

    Glad you know you limits. For lots of shooters on here a shot at that range will be meat and drink

    .243 load

    Oh dear....

    .243 load

    Well just replicate the Federal load ?

    Advice needed. Chamber issues

    Give it back to the guy who sold it to you and neglected to tell you about the problem. Refund or small claims court. His choice ?
  6. Google... Parallels or BootCamp are two options....

    If you have a good dog, don't let it out your sight. The 'caravan club' wait round the corner, entice the dog over, chuck it in the back of the van and that's it. If its lucky it gets sold on, if not their fighting dugs get to practice on it. Scum of the earth, don't care what the politicos think. Lots of poachers at these Game Fairs. Doesn't surprise me in the least. Let the wife sit on her own not yer dog....?

    Double rifle sling

    TAB Gear
  9. Thought that was a manhole cover or something ??
  10. I must mis-understanding something? Presumably after reloading they have created a round that would require a FAC for legal possession. So how can a non FAC holder reload ?

    except a wife....
  12. I found this useful... Which bipod

    Muzzle tread ?

    M18x1 is a common threading. Just buy one.

    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....
  15. 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.

    6.5 PRC

    What is it that the PRC gives us that we can't already get ?

    Anybody got a set idly sitting in the cupboard ?

    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...
  22. 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 ?
  23. 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.
