ive had pretty good luck with the 429 bullets, jacketed tho, in my rem 700ml and my ruger 77/50.i tried cast 45 cal 451 dia bullets with the appropriate sabots,230 grn i believe. they just were not near as accurate.dont really know why tho.havent tried any 44 cast yet. but i need to, just dont have that mold yet as i dont have any 44 cal guns that i cast for.
