I shy away from +P loads as I don't want to beat up a good gun.What’s a good Unique load for a 230 gr Berry’s bullet for a 45 ACP +P round?
From Berry’s website:That load is skirting with the upper end of velocity prescribed by Berrys (975 fps max).
I’m not sure what the negative event above 975 fps is supposed to be. Stripping of the plating seems unlikely. It is perhaps terminal performance, as Berrys “magnum” bullets are advertised to have thicker plating?
In any event, you may want to work up to + P velocities rather dive right in.
For what barrel length?Berry's max recommended velocity is not exceeded. (This info is displayed on bullet boxes and product webpages.)
- Standard Plate Bullets Max Velocity: 1,250 fps.
- Thick-Plate Bullets (TP) Max Velocity: 1,500 fps.
Doesn't matter, just the velocity.For what barrel length?

I would assume it matters just like lead, that they would have to be tough enough to hold the landsSo if it's a velocity thing then why doesn't a 1 in 10 twist have more affect on the plating then a 1 in 16 twist?
That’s directly from Alliant’s Unique recipes for 45 ACP.

Well, the first assumption here is that Speer's CPRN and Berry's CPRN are identical or nearly so. That's probably a fairly safe assumption. "Probably"That’s directly from Alliant’s Unique recipes for 45 ACP.

I load 6.5gr Unique with a 230fmj. Seems reasonable and shoots accurate with all my 45acp handguns.
Of course guys, these Alliant recipes using Unique are for the 45 ACP and not the 45 ACP +P. And all Alliant recipes lean toward caution.
The Alliant load of 7.3 Unique is for a jacketed bullet.
