Pressure signs

well if they are .2085 after 3 reloads i would guess your pressure is either fine or just barely over I would back it off a half grain You will see minimal if any velocity decrease as a lot of loads tend to Plateau as far as velocity goes once they hit the peak until they hit a certain over pressure then velocity shoots up. sounds like your accuracy sweet spot is right where you have them seated. if you back them up your group is likely to increase in size. I would bet if you backed the powder off a half grain maybe even a full grain if that makes you more comfortable you would still have great velocity and keep your accuracy. I hate to see you sacrafice accuracy for velocity which is no more than a number. Not to mention even if you lost 100 fps (which you wont)you would probably never even see it.

I think that is exactly what is going on. What velocity are you getting? should be around 2900 -3000 I would have to look it up to be sure

I figured that it would come down to reducing the powder charge. Except I have and anything below 60.5 grains is shooting somewhere around a 1.5 inch group. I will need to try a different powder possibly to get better accuracy in those lower charges.

Well if you feel you can not go down with your powder charge I suggest you pick 5 shells and keep loading those same 5 with the load you have worked up right now and see if the primer pockets expand eventually. they very well may not. If they dont expand after another 3 or 4 loads I say shoot that load and call it good. If you are getting good results and not wearing out brass and nothing dangerous is happening I would say you have a great load!!

Sounds good thank you.
