There are a few of you on this site that reload.  I'm no expert and I am still learning a lot.

I've been reloading .45ACP for a while and I'm trying to get your thoughts on bullets.  I'm not casting my, I buy them.  On the shelf I can buy them in .451 or .452.  I've read all over the interwebs and through all of my manuals.  I've reloaded both and shot both and I haven't noticed any difference.  For anyone in the know, what are your thoughts, cautions, or concerns (if any) with using .452 projectiles?

Stick with the .452 bullets.  They are the proper size for this cartridge.

.451 bullets are for the Colt 45.

I've read most of this before.  Every manual gives recipes for .451 and .452.  Some say .452 is just for cast bullets and .451 is for jacketed or plated bullets.  Not sure what is the most correct or if it even matters.

 

I like the gun talk!  

I haven't done 45acp yet, but the reloading subforum on ar15.com is pretty good and rigidly moderated unlike other parts of the site.

I do cast my own though and will get molds for 45acp soon.

You mentioned casting boolits a while ago on this form.  I never had any desire to get into that, but after you mentioned it I started watching YouTube videos and I'm interested.  I've got to come up with the cash to get some things to get started.  I'll pick your brain, CSM, when I get to that point.
