[QUOTE="johnnyk, post: 170747, member: 307"] I seem to be having that problem also. I'm shooting a stock Rem 700PSS in 7mmRM. Using RL22/R9.5m mine shoots the 140TSX in to .4525" using 68.5gr @ 3234fps. I tried 69.0gr and velocity averaged 3297fps but accuracy went to .9570". Does anyone know what the max load is? I'm not seeing any of the obvious pressure signs. I may take it a little higher. I've tried the 168gr SMK, 150gr NBT, 154gr SST and yesterday I tried the Berger 168gr VLD. The best of all these was the 150gr NBT at .3835" using 65.0gr of RL22/9.5M for average velocity of 3021fps! The worse was yesterday session with the 168gr Berger. I tried 63.5-65.0gr of IMR7828 with Fed LRM primers. Best accuracy was about 1.0" with the worse being 2.5-3.0"!! The powder's I've tried so far have been H4831SC/RL22/IMR7828. Primers have been CCI BR2/9.5M/215. I'm beginning to think this rifle likes the lighter range of bullets! I dunno but I ain't given' up yet. JohnnyK [/QUOTE]
