I took my new Savage 12 in 22-250 (barrel twist measured at 1:11.75, or approx 1:12) out to the range for some load work. I started with factory loaded Federal 55g Nosler Ballistic Tips as a baseline to get on target at 100 yards, then switched to handloads, 52g Hornady ELD and 53g Hornady V-max, loaded at 2.350". As velocities increased (starting around 3500 fps and increasing to just over 3600 fps) the 52's began to keyhole big time, going through the target sideways (!) when they hit paper at all. No problem with the 53's at roughly the same velocity; my best 5-shot groups were in the 5/8" C-T-C range. My experience was the same using both Varget and 4064. Any guidance? Should I be loading 52's slower? or even faster? Did I load too "short"? The Hornady manual calls for 2.350". I'm going to try 55g and 60g bullets as well...maybe 52 is too light?
