  1. Agree with that. FL size at the start. You'll probably want to re-chrono your load and adjust as necessary (for velocity) each powder batch and for significant changes in temperature anyway (keep notes for each load based on powder batch number and climatic conditions). Just looking back through some 223 load notes, there was far less a difference (ie negligible) when FL sizing from the start over just firing new brass. You'll want to do the same for any changes to primer but appreciate you're probably already aware.

    UKV site not secure?

    Generally, it means that a site may not have a valid SSL certificate and in reality may have very little to do with how secure it is or not. For example, some sites may well operate with secure encryption, but may not have applied for or paid for an SSL certificate which is a standard of encryption preventing hackers stealing data between transmission and reception of site data. With SSL in place you get the green padlock symbol. My own website is safe (or so I'm assured by its builder) but I haven't paid for the SSL (yet) hence it also shows "not secure" even though it uses secure encryption.
  3. I have had differences between new and fireformed, with higher velocities from fire formed in each case (up to 50fps for the same load). I think a lot depends on your chamber and the energy expended in fire forming the brass (but may stand corrected here as I'm unsure of the exact reasoning) rather than propelling the projectile. Rule of thumb purely from my own reloading notes shows a clear difference, never so more marked than with my 6.5 CM loads (initial MV with new brass was 2680 to 2700fps and 2750fps give or take for the fire formed for the same load). I guess it also depends on the brass used to start with. To caveat my experience, that was using Lapua brass.

    223 rifle choice - what ????

    Exactly what I did and couldn't be happier with it. It's accounted for countless vermin over the past few years and even some small deer. Had fun with it at 600 yard target too. It's now sporting a Nightforce NSX scope. There's something just right about the feel of the little mini-mauser action. Stock's a Boyds which I inletted a little more and had fully Devcon bedded. Re-barrelled this on with 26 inch 1:8 target profile (much lighter than varmint heavy) Lothar Walther.

    Which RWS powder ?

    Yes..never seen it for sale.

    I'm afraid I don't know know the answer to that but 3 months seems long enough to be chasing someone up! The fact that a few that I know had problems with their Crusaders steered me towards the PMII when I was looking for a reliable top tier LR scope and was enough to put me off the idea of an IOR no-matter what I thought of the glass (which is excellent).

    Small Rifle Primers ?

    Best NOT using standard cup thickness SR Primers in CM for the same reason you ought not really to use them in .223. It needs thicker cups due to chamber pressures, so Magnum or any other 0.025" thickness primer cups are the ones that are recommended. Murom KVB 223Ms, CCI450 or BR or equivalent. I use both the Muroms and the CCIs.

    Recomendations for reloading manual

    Lee Reloading Manual is about the best in terms of being the most comprehensive and containing tonnes of useful advice. I have lots of them, inlcuding the Lee and the Lyman but the Lee Modern Reloading 2nd Edition is the one I'd recommend above all others. It contains a lot of blurb about how Lere kit is all you need and carefully thought out...that may well be the case for some but take that with a pinch of salt and listen instead to the advice on reloading and you'l not go far wrong. Well written, comprehensive load tables (even if new REACH compliance rules a lot of the powders out!).

    We don't review scopes though...we use them. I don't think personal preference counts for much with scopes...they're either fit for purpose or they're not. They either measure up to your requirements, or they don't. I have used them professionally as well as for leisure sport shooting and have always reverted to a scope that does the job in hand reliably and with the optical quality that cuts the mustard. Feature rich scopes are like feature rich cars....mostly redundant flippery. The PM2 is popular for a reason...it has nothing that doesn't need to be there, isn't perfect but has proved reliable the world over and with superb glass and turrets with possibly the simplest zero-stop system in existence. It's reliable, rugged and fit for purpose. "Better" needs definition. Better at what? Optical resolution? Reliability? Tracking error? It's pretty good at all of those things, if not the best at any of them. The IORs divide opinion precisely because of their model specific odd colour cast (done for a reason to aid contrast in low light perhaps?) because of the thick rets and because of the so-so reliability record. Get a good 'un and it's probably going to be the mutt's nuts. Personally I love the way they handle and like the glass. Get the odd Friday afternoon one and you may wish you hadn't bothered. There seems to be a fair few conflicting opinions and that in itself puts a lot of people off especially at the price.

    What scope?

    Bushnell DMR, Vortex Gen2 Viper or Delta Stryker as above. All great scopes for the purpose. Most robust is the DMR and imho, it has the most positive turrets. Viper Gen 2 is up there with the glass quality of the Razor Gen1...really a leap forward compared with the Gen1.
  12. VarmLR


    Mixed reports. Glass is excellent although to my eyes it had a slightly odd colour cast (Recon). In terms of reliability I know several shooters who had to send their Crusader scopes back following turret failures. Personally, I found them a little chunky, fab glass though, but for me the dealbreaker was the ret thickness (Don't know if IOR now offer a fine ret but I haven't seen one). I ended up going down the PMII route instead with no regrets. The other scope in the same bracket well worth a look is the new Vortex Razor Gen 2.

    Reloading bench size / area

    You don't need much. A clear area for loading of perhaps 600 x 600 and about the same for the press, any trimming tools etc and perhaps a shelf or two to store dies, powder and the like. I manage with a 600 x 500 double thickness ply board with a wilson/sinclair hand lathe trimmer, Lee press and a few other tools on it. I store it on top of my tool chest when not in use and it gets transferred to my compact workbench (1.4m x 0.6m) when I need to do brass prep. I load in a separate draft free area.

    Pressure rise can be significant when seating on, or close to the lands so, personally, I wouldn't advise you go there unless starting load development from scratch. Don't forget there's variances in base to ogive with most bullets, so a actor of safety is wise. My theory about altering seating to shrink groups I think is less to do with barrel time (which by definition must remain pretty similar for such small changes) being affected by seating depth per-se but more to do with pressure rise as you approach the lands and uniformity of ignition as you seat further back (effectively increasing fill ratio behind bullet). I tend usually to find two nodes on seating (at least that's what I've found....so not claiming it as a rule, just from experience). One usually within 30 to 40 thou and another further back in some cases by 100 thou. My reasoning may not be technically gospel here...it's just after putting some thought to this I can't see any other obvious mechanisms at play. This all assumes tangent or hybrid ogive design. Secant ogive bullets are a different thing entirely and for the most part like to be close and personal with the lands.
  15. I bought 1000 Muron KVB-M primers some time back and they seem to be very consistent and produce low ES figures albeit modest MVs. I won't now use their standard small rifle primers though, even for moderate loads in my 223 (yes, I know I ought to use magnum ones for that) after they blew/split at the edges and gas cut my bolt face. I also have some CCI450s to try but haven't got around to using those yet.

    My own rule of thumb for jump tolerant bullets is to use a COAL which allows close to 100% fill or slightly compressed powder fill beneath the bullet if possible. Failing that I usually load to mag length and only tweak if needed.

    Measuring performance

    If it's cold shot from a clean barrel, I first fire a fouling shot before my scoring shots. Some barrels just do shoot off on the cold bore (clean barrel shot). The other factor is technique. It didn't take me long to suss that my first shot was always (almost always) not correct on technique, so now when I settle down I do everything by the numbers, move head away, return to cheek weld and check cross-hairs. If off target even by a smidge, I shift body position and try again and repeat as many times as needed until consistently on the bull with the cross-hairs. I also twigged that my first shot was with too tight a grip on the trigger finger hand so deliberately use a very loose grip now, and concentrate on consistency with trigger pull with hardly anything touching the rifle except the trigger finger. These few bits of discipline have done more to tighten up groups than firing off group after group and blaming the loads...when all along it was me. Finally, a stone cold barrel has a round in the chamber that has powder at ambient temperature. Even if the rifle has only fired a few rounds, the chamber temp' comes up very quickly and any subsequently chambered rounds will see a rise in propellant temperature which can (and does) make a difference. None of the above could be factors MiseryGuts for your case or some or all of these things might figure?

    Measuring performance

    For group analysis and especially for ES/SD measurement, I always use 5 or 7 shot groups as statistically, they are the sweet point of statistical relevance V's economy. I don't bother with target software the data would be lost in translation due to the number of shots fired annually. Comparison of groups for me has to be done on a day by day basis as a group shot last year with a load may produce very different results than one shot today despite theoretically me shooting the same...too many variables to get hung up or stressed about the conclusions, not least of which is weather. I do analyse groups for technique and for comparison a la OCW, and also pay attention to velocity measurement when load developing. I do keep a notebook and do try and learn from data of last outings (DOPE), working this into any planned alterations of load, shooting position, technique and such-like. Expectations are fully dependant upon conditions and rifle being shot for me. On a good stillish day with my 6.5, I would expect 1/4moa at 100 yds all being well but be happy with say 1/3rd moa. At 200 yds, I would want to see 1/2moa. At 600, I would want to see 3/4 moa (my last outing saw ten shot groups bang on 4 inches) and at 1000, I want to see no more than moa which I think is reasonable for an off-the shelf factory rifle and decent ammunition, so my expectations are not that high compared with competition shots. I know that these goals are within my/my rifle and load capabilities and as I don't shoot for competition my shooting is geared around practise for more surgical vermin control, yet I rarely take shots on anything live over 400 yards (ie I limit range for certainty of outcome). Confusion doesn't reign for me at all. I approach my shooting and load development using a very detailed, systematic methodology and keep good records. Where I do strive for perfection though is for me perhaps the most challenging aspect of shooting...first shot on target centre shots at distances both known and guesstimated. This is the real skill for me as load development is really quite straightforward and the means to an end. It's then what I do with a good load that matters more to me. This is where one of my real shooting passions kicks in which is the study of ballistics as this for me is where the real interest lies. It's the skill of putting all that hard earned knowledge and practice together to pull off that one shot, one target bang on centre result. I still struggle with this but am getting better. I can usually land my first shots somewhere handy up to 1000 yards, usually within 2 to 3moa conditions dependant, but that's not good enough. I would like to manage moa terminal goals for first shot, and that takes a hell of a lot of practice and learning to read conditions properly. The reason for this is that now, when in the field on vermin control, my confidence and ability to 400 yards is such that I'd be very disappointed to miss what I'm aiming at first shot, and after a good number of years practice I can say with some honesty, that I rarely miss these days. I don't compare my shooting with anyone else's and just strive to improve my own technique and knowledge as part of enjoyment of the sport. I do try and learn from others more learned than my self as there are so many advanced shots and knowledgeable people out there (and on here!) from whom to learn and adapt.

    Yep. 44.3 all the way. Have you chrono'd your 5 shot groups to establish ES/SD? Don't overlook this as a way to determine how the load might perform further out. In fact I'll push the boat out and suggest from every bit of reloading data I've seen to date using the SRP brass, the 139 Scenar, RS62 and 24 inch 1/8 barrels, at least in Tikka and Ruger, that just about everyone who tries reports back that a load of anywhere between 43.9 to 44.4 is the sweet spot for this combination with velocities varying depending on temperature and barrel from 2700 to just under 2800fps, depending on seating/pressure. It's just one of those combinations that seems to work well and one I arrived at myself.
  21. As above One load for all distances for me (saves messing about with different combinations and helps learn your drops and drifts). 44gr RS62 under 139 Scenar using Small Rifle Magnum primers, 20 thou jump. 2700fps. Jobs a good'un (24 inch/1/8 Tikka Tac A1).Good from 100 yds to 1000 yds. Gives about 1/3moa (7 shot group, still conditions).

    .260 rebarrel

    1/8 at 24 to 27 inches is more than adequate for 1000 yds using 123 or 139gr Scenars IME with plenty left in reserve. There's been some testing ( Accurate Shooter I think it was) of barrel lengths v's velocity for 6.5mm, albeit in Creedmoor, where 20 to 24 inches was considered fine, but that's a close enough approximation for 260 too depending on the chamber throating (ie will it take longer pills at mag length?), and one the outcome in another test was that with some powder/bullet combos, velocity started dropping off after 27 inches I think it was. A lot depends on powder burn rate and bullet mass/sidewall bearing length so no two comparisons might have the same conclusions but for general duties and target to 1000 yards, 24 inch barrel should be more than adequate...why carry a 30 inch tube about if you don't need to? For purely competition work in 6.5 you might want to consider something a little longer.

    Lee seating die (6.5CM) and Sierra 142gr MK

    Yes, that's a very fair point Mike. I like the Redding seating dies. I have the micrometer head on mine which is surprisingly useful and bob-on once set.

    .223 Reloder 15

    I'd stick with Viht or RS powders NJC. Looking at your cases on Sunday, your description is not an exaggeration! I use N133 up to 60gr and for anything heavier in ,223, RS50 works very well and burns really cleanly. It's be a great choice for the 65 gamekings. I tried N140 with the 60 to 69gr bullets but using RS50 achieved better groups and higher velocities. N135 might have been the better choice over N140 though for the 65gr.
