I have about 500 230 gr. lead round nose boolits that have been powder coated and sized to .452. I have a 5 lb. can of IMR PB left over from my shotshell loading days that I want to use. My Lyman Cast Bullet manual, 3rd edition shows load data for 225 gr. boolits of 4.8 - 5.5 grains of PB but nothing for 230 gr. My 4th edition manual doesn't list any loads using PB for either weight. If it matters at all, I will be using Win NT brass with CCI #300 large pistol primers.

Can anyone give me some load ranges for the 230 gr. boolits using the PB powder?

These will be used in my Colt 70 series 1911 mostly for plinking and practice.

It's only 5 gr difference between the boolits...the friction difference between lubed and PCd, and any difference in finished diameter, will make more difference than the weight. I'd knock down the min/max 0.2 or 0.3 gr each and go for it.
Four decades of loading .45 ACP tells me you're worrying too much unless PB is an AWFULLY twitchy powder.

win nt brass is small primer

That's what I thought too but I have several thousand new Win NT I got maybe 7-8 years ago and it is all large primer. I had actually bought a case of small primers for it about the same time and found it was large primer size. I rechecked it tonight with a Ballistic Tools primer pocket gauge and it definitely has large primer pockets.

The Hodgdon data site lists data for 45ACP using PB for a 230 grain lead round nose. Their data suggests a somewhat lower charge than yours.

I'll bet 5gr will make a good load.....

FWIW: Once upon a time, I burned a lot of PB shooting trap/skeet and, because I always had some on hand, also burned a fair amount in .45 ACP. According to my old notes, load was 5.2 gr., Fed LP primer, and a lubed 225 gr. TC in milsurp brass. Must of worked pretty well, because other than a 185 gr. 'softball' for my bullseye gun, it's the only .45 ACP load in my notebook from back then.

You can bet all you want with your pistol. I won't gamble with mine.

Hodgdon says 4.7gr is max at 15,900cup that is quite a bit under SAAMI but then Hodgdon always lists low max pressures and usually lists optimistic velocities for same. JMHO-YMMV.................

They also list 5gr with a jacketed 230gr at 16,500cup.

I use 4.5 grains of Winchester WST behind a Hardcast 230 grain RN and basically this is the only bullet powder combo I've used in a 1943 Ithaca and a newer Springfield 1911A1 With all the bells and whistles.Frank
