for some reason when I search the forum's on this website it never provides any results, no matter how generic I make it. I had started one thread like this about 6 months ago when I got the gun.
However, I'll get some of my data for you tonight or tomorrow and get it posted.
I had the best luck with the 130 AccuBond and H4831sc with about 0.001 jump to the lands. The 142 SMK didn't group as well. I've finally got some 140 Berger's to try but haven't had time to load any yet. The 130's were just over 3200 MV and the 142's were around 2950.
Like I said, I'll look for the powder charge tonight and get it to you.
