88 Eldm 22-250 8 twist keyholing - 12/03/19
Hey guys, anyone had any luck with the 88s in an 8 twist? I tried running up charges in H414 and RL16 and even over 2900 fps they keyholes. I have tons of other powders to try...thinking maybe Rl23 or 26? I'm running a 22" barrel .020 off the lands. Hoping for a good 800yrd round for varmints. I'm running 75 bthp at 3200 and 77 Tmk at 3180 with good results. Just not having luck with the 88s.
