Sorry for the late response. 41.6 grains of h4350. 115 dtac. 3180 fps. I used it for prs matches. It was a screamer. This was also years ago when I thought I had to have something very fast unlike today. I was using norma brass which will hold a ton more pressure than any other 6xc brass out there. When I switched over to Peterson brass I could barely hit 3000 fps without pressure signs. At 3180 fps, I pulled the barrel at 1200 rounds but it was still shooting good.
