Whats the slowest twist rate that will stabalize an 80gr bullet for a standard 6br? Still trying to figure out what twist rate I want for my next gun, and I'm leaning towards shooting 80gr fowlers at longer ranges. Most of my shooting is at 100-300yrds, occastionally out to 500yrds. I was thinking 1x14, but might drop that to a 1x12.. any thoughts?
