Hey y'all!
I recently got an old Sako Finnbear A3 in 300 win mag, and I understand that rifle has a 1:11 twist barrel. I took it out to the range and shot groups with 150gr Hornady interlock bullets, 165gr Barnes TSX, and 180gr Hornady SST. The first 2 shot fine, but I couldn't get the 180gr load on paper at 100 yds. I brought my target back to 20 yards and grouped about 1.5" at 20. So I'm wondering, will a 1:11 twist barrel stabilize the 180gr SST? I can't think of any other reason it isn't hitting paper at 100.
Also, the 165 impacted about 5 inches to the left of the 150gr at 100 yards. I don't know why a different bullet would group that far left/right, so if anyone has any ideas, please let me know.
Thanks!
