That's awesome!flippn sweet!!! Mine is a PCR barreled action job to a stiller predator action. Had some 4350 but felt I needed something a touch slower, so I tried and tried till I got a 8# stock of 4831sc last week, and it looks good and it was hard to find some data on it so I thought I'd post it just to help out. Gap did a 22-250 with a 8 twist barrel for me this spring. Shootin the 75gr bergers with 4350 at 3200 fps is a PD Killer out here and I cant wait to test it on Yotes!! Rock On!!!!!!
