You might find some folks that shoot more actual Berry's bullets than I do (maybe they shoot steel every week in competition), but only in volume. I don't know of anyone in this forum that shoots a larger variety of Berry's plated slugs than I do.
I shoot their .32 cal 71gr plated RN, the flat base 100gr .380 slug, two different 9mm plated slugs, a .38 cal plated flat point, a 180 grain .40 cal flat point, two different 200 grain .45 slugs and I love their .30 cal 110 grain bullet in .30 Carbine outta my Blackhawk.
But I don't anticipate using their .44 cal bullets... because when I load .44 Mag, it's .44 Mag. It's got a heavy crimp (as it should) and it's got nuts, as a .44 Mag ought to. Neither of these conditions is good for plated bullets.
Any kind of a real roll crimp (as the .44 Mag begs for) is seriously detrimental to any plated bullet. And Berry's suggest that all the typical handgun bullets don't exceed 1,200 FPS, which .44 Mag certainly does.
For .44 Special loads? Perhaps, but I don't shoot the Special.
