[QUOTE="vegas steve, post: 655406, member: 47484"] i have a savage 112fv in 7 rem mag and shot only 71.5 grns of rl19 behind a 120 grn balistic tip and was seeing faster speeds than i imagined around 3680 fps. my barrel lasted about 700 rounds before the accuracy went south. upon bore scoping the bore,i found that not only did the barrel suffer throat erosion,i actually lost three lands at the front of the throat that seemed to have broke off completely and also had a bad case of fire cracking as well. the 7 rem mag is still my favorite caliberbut the next one i build won't be getting any rl19 fed thru it.gun) [/QUOTE]
