Results: Shooting 180 grain bullets in a 1:12" 308 Win barrel
I did a good bit of searching online a few months ago, and found no evidence that a barrel with a 1:12" twist would stabilize a 180 grain bullet in a 308 winchester. I finally bought some Sierra SBT 180's and tried them out. That group was shot at 300 yards. Just thought I'd put it out there for any others that were curious about the matter. Merry Christmas!
