I am using a Carl Gustaf 7mm Rem Mag with a 3.5-10 Zeiss Conquest. As for the bullets...this is the run down: 110 gr TNT, 140gr Silvertip, 150gr XBT, 150gr Nos. part, 154gr SST, 162gr Hornady int. Temp was about 15deg. C & absolutely no wind! I did shots of 3 and waited for the barrel to cool. I am using cci magnum primers and all federal brass, powders are as follows: H414, H870, H1000, H4350, Reloader 22 & IMR 7828. I loaded every combination available using just under max loads for each. Now that I have 4 ok loads at 100 I'm gonna try tinkering with them and see if I can group a bit better at 200. JDinAB
