Re: accuracy of once fired/new brass vs. multi fired
As far as the fired -If it is sized properly,wont really see a difference. If the gun/load combination is right its just gonna shoot good. When you find the middle of the node/ window they just run!
Re: accuracy of once fired/new brass vs. multi fired
I noticed a difference when I got to 5th fire and above. Did a side by side of 2nd fire vs. 6th fire with two 5 shot groups of each at 200yrds all prepped the same.
The 2nd fire grouped at .87 and 1.33 vs. 2.45 and 2.93. Taught me the importance of annealing.
