[QUOTE="RegionRat, post: 2745531, member: 57231"] [URL]https://www.ammoman.com/blog/5-56-twist-rate-chart/[/URL] [URL]https://www.everydaymarksman.co/equipment/rifling-twist-rate/[/URL] [URL]https://bergerbullets.com/twist-rate-calculator/[/URL] Opinions on the high and low ends of twist for any given bullets vary. But since the OP asked for experienced opinions.... I have burned up my share of personal AR barrels on colony rodents. On many occasions, just for kicks, I have put 40 gr V-Max through the heavy bolt guns with 1:7 twist and some of the bullets blow up. A 50 gr should make it in a 1:7 without blowing up, but that isn't the main point. A 1:7 is optimal for 77 and 80 gr match bullets. It can run 55 gr at short ranges no problem, but it really isn't meant for this. The OP wants a barrel specifically for burning up a pile of 50 gr V-Max ammo. If I have a pile of (40 to) 50 gr V-Max ammo to burn in an AR Varmint upper, I'm probably reaching for the 24" 1:12 to 1:10, not the 1:7 YMMV [/QUOTE]
