Been loading 240 grainers in .44 mag a long time. I really doubt if you will see 1850FPS outta any of those guns. Biggest concern I have is that the bullet in your link, has no cannelure. To get those kind of velocities, a heavy crimp is needed for the slow burning powders(as in H110/W296). Hard to do without a cannelure to roll crimp into. Then there is bullet jump from the heavy recoiling loads, also why a cannelure is suggested.
If the number’s real, perhaps they’re catering to lever action rifles as well?
Speculation on my part.
I’ll be calling Berry’s tomorrow to confirm.
Might try a few of their bullets for kicks, but I’m kinda leaning away from them.
Another bit of info I need - are tight crimps as necessary when rounds are fully chambered (lever action rifles, Desert Eagles) in the usual sense? I’m under the impression that the bullet being jammed into the leade precludes the need for a tight crimp, whereas revolvers need it to prevent the bullets from catastrophically sliding out while in the cylinder, and to compensate for pressure losses during the “jump” at the barrel / cylinder gap.
In light - recoiling semiautomatics, one worries more about bullet setback than excursion (jumping the crimp) as the magazine prevents the latter. To stretch the context further - bench shooters once favored lightly seated bullets + loose necks but tight chambers.
