My first .452

[filric48]

These are the .452 230gr I cast the other day, need to re size to .451 and lube and my new Water Buffalo Grips.

They look very good -- I just see one bitsy wrinkle in the lower ledt corner of the photo :-)
Lee mould? what lube and sizer?

[CalTeacher]

So why are you sizing down to .451?

[bumpo628]

You should be able to shoot lead bullets at .452 in most 45's. I would still run them all through a .452 sizer to make sure they are consistent.

they look good what mold are you using?

Lyman book says to re size to .451 Lee mold and re sizer.

Lead bullets are usually sized down to .452.

[CalTeacher]

Shoot them at .452 first. Have you measured a sample of the bullets yet? My molds often throw. 001 over what is listed and I still don't resize because they shoot really well. My .452 lee mold for 230 gr boolits actually throws .453 sized boolits and they shoot great. Unless you have an exceptionally tight bore, leave them as is, lube and shoot. An undersized boolit will lead your barrel badly and lead to poor accuracy.

I suggest that you slug your bore and figure out which size you should go with before simply applying any advice getting thrown out.

+1. 0.451", the nominal barrel diameter for .45 ACP (and .45 Colt after WWII) is typically for jacketed bullets. Cast boolits need to be 0.001" larger than the bore size for optimum gripping by the rifling.

BTW...good looking boolits there. :-)

there wrong try them at .452 first.
I have leading like a swerer pipe in 1911's if they are .451 at .452 NO leading at all.
I also tapper crimp to .471

[eaglemike]

Another vote for .452. Unless you slug your barrel and it's .4505 or smaller, you'll have better luck with .452. A little less leading too. The proper tight fit is good.

Good point...For me, I don't use the Lee Factory Crimp die with Moly's or Lead, but the Dillon Taper Crimp die.

I do not think you have slugged a barrel before. I did it ONCE and it HURT. Gave my knuckle a bruise for a two week span...

Never again will I do that and it did nothing for my accuracy but put a ding on it when it flew out of the vise and onto the floor...

I slugged a Finnish M39 about a year ago using this tutorial. I was researching if reloading would be worth it for that particular rifle, but I never got around to buying the dies for it. I have never bothered with bore slugging again and all I know is that many of the old timer reloaders, that I have personally spoken with, advised doing so if you are going to shoot self casted lead bullets. Perhaps times have changed?
