[QUOTE="ShootnMathews, post: 2786938, member: 59915"] We all have our own style. Myself I always FL size and set the shoulder back .002” and that produces great accuracy for me in most of my rifles. What originally made me post this thread though is I switched from federal brass that I worked the load up with to new Lapua brass. Now when I’ve done this before with other rifles the groups always opened up and needed some charge tweaking and even at the best charge always shot bigger groups with the virgin brass and then tightened back up with the once fired brass. But I have never seen it this bad. My load that shot reliably under 1/2” went to well over 2” when I went to the virgin Lapua brass which made me question many more things about the load. Now, when I took some of the once fired brass and reloaded it with the same charge it shrunk to a little over an inch which is more like what I expected from the virgin brass. After tweaking the charge some I now have it down to almost 1/2” and I think the loads I shoot tonight will be under 1/2” if the trend continues. So I’m not going to say I got a bad batch of Lapua brass I’ll just say this rifle really likes fire formed brass. 🤷🏼♂️ [/QUOTE]
