Using the MId-South, 62 grain Hornady HPBT bullets in a 1-9 twist .223 bolt gun with 25 grains IMR8208 gave good results. 27 grains of Hodgdon 223CFE also worked. Drop at 300 was .5 mil with a 200 yard zero. Bullets were seated some distance out from cannelure so they almost touched lands - no magazine constraints. Consecutive hits on 3 inch diameter steel at 300.
