I take it the primer pockets are still fairly tight. Yes, the Win primer will flatten right out if pushed even a little bit too far, giving a good warning that you need to back off. On sunny days, you'll get your best reading at around 9-10am and again in the late afternoon provided there are no shadows. Sometimes a chrony will play up around noon when the sun is shining from directly behind you. It can also help a great deal to test the chrony with another rifle / cartridge of a known velocity or test your rifle over another chrony if using a shared range. It will be best to check the angles of the chrony next time you set up and make sure it is a good 13 feet from the muzzle. Hi Douglas, it may just be a chrony issue. So, either my chrony is way off, or? Any helpfully advice? Max speed from the published data on the 200 is 2900. Neither of those last two loading showed high pressure signs either. Forgot to mention RL-22 for both bullets. Next the last two 200 gr8 ELD-Xs have shot 29 fps. Am I pushing this too far? The temperatures were in the 60s and sunny, so relatively warm. Winchester I read has soft primers, and yes they are flattening out. The primers are Winchester magnum, as are the cases. But my question is speed alone enough to worry about pressires? There are no ejector swipes, blown primers or the like. I had to do this due to magazine length, something I hope to change. I am seated a long way from the lands.097". No powder compression, but there isn't any space left behind the bullet. This load what I am calling max has the best spread. Up to that point I was getting spreads of and where from 35-70fps. What is confusing is the speed I am recording. I have stopped loading higher at this point. I am competent at reading pressure signs, and thus far I have exceeded the max loads with very little signs of excessive pressure. I am a bit perplexed at my results so far. Started loading 165gr Hornady SST bullets and a hand full of 200 g ELD-X. I know I'm over-gunned, but I like the combination. I will primarily hunt deer, with the occasional elk hint thrown in. Got it back, reglass bedded the stock and began to work up loads. They checked headspace after installing the new to me barrel. Had it professionally done at the most reputable gunsmithing company we have here. I got a very lightly used barrel from my cousin and changed out my Winchester M70 in 338 Win Mag to a 300 Win Mag. I have the reloading, long range shooting and bolt action accurizing books so far in the series.
