Welcome to the club! I recently finished working up 140gr Partition loads for my Rem SS BLD 7MM STW...
My best groups were with IMR 7828...the winner was 80gr with a 3.649 COL..... 0.277!! :shock: It shoots under 0.50" at 200yds with this load off the bags.
I am really pleased with this rifle...I only added a Timney trigger kit to the stock rifle. I just ordered some 160 gr bulloets to develop an Elk load...will keep you posted.
