A question on 50 cal.

[HPBTMTCH]

smokepole, the one in 28 twist or slower will not stabilize a .224 projectile. I have had a little success with the .45 cal. sabot in a .50 cal. sabot using a .40 cal. 135 gr. nosler pistol bullets, but some ML`s won`t shoot a very good group with them. There are a few (expensive) frangible .44 and .45 cal bullets out there, you might try those.
