I'm getting around 3100fps and 1.5"- 2" groups @ my 250 meter zero. I just started working up a load with 175gr Sierra GK's with VVN570 and am getting a surprising 3170 to 3220fps. Shooting at 100yds. my groups have varied from 1.5" to 2.25" but their POI are real close together and I show no signs of pressure but that is 100+ fps faster than I expected. I think I may have something to work with though.
Dchamp, first of all, welcome to the website, and " The Brotherhood". Nice looking stick you have there, and some Beautiful country in the background.
I think maybe the reason your 160 bullets are slower then your 175's , is that the powder you are using may be too slow for the 160's, and your barrel length. I could be wrong, but dosen't your rifle have a 24 inch barrel ?
Anyway, it is working fine for the 175 grain bullet. That speed is darn good!
I love that laminated stock. Nice job, and again Welcome!!!
