[QUOTE="dchamp, post: 1044423, member: 51652"] I have not shot the 180gr Bergers but have shot 175gr Sierra Game Kings with Vihtavuori 570 up to 84gr's of powder at 3200+ fps with no problems. I found my best accuracy with 81.3gr's of powder at 3080fps. I also have a load of 160gr Accubonds with 81.5gr's of Vihtavuori 570 thats around 3200fps. Both of my loads shoot fairly well right around MOA, but not as good as what you have shown. My rifle is a Ruger #1B with a 26" Barrel. My Seating depth is a std. 3.65" with WLRM primers.I think Vihtavuori 570 is a good powder for the 7STW. I've tried Retumbo but wasn't happy with the results. Have not tried RL33 but it looks interesting. In my mind powders like Vihtavuori 570, RL33 & Retumbo seem to be about the right burn rate for heavier bullets for the 7STW. [/QUOTE]
