.45 acp & .45-70 question

hbhobby · April 29, 2013, 08:34 PM

I am wanting to reload my .45 acp and .45-70 for just plinking. I have looked in the manuals and the biggest bullet listed for the .45 acp is smaller than the smallest listed for my .45-70. So my question is if there is a bullet that will work with both guns? And if so where do I get the loading data? I have 6 different manuals and none of them have one bullet that will work for both guns.

45 ACP is .452 in diameter. 45-70 is .458. Can't be done.

Well, you can but it's not easy. You could paper patch up to .458, but why bother?

I have an insert for my 45-70, chambered for 45 acp !

Accuracy ?

It probably SHOULDN'T be done. You'll find that even among other .45 calibers the bullet is different. .45 Auto is .451, I think .45 LC is .452 and heavier for example. Though I've seen that the Berry's cast .45 Auto bullets are .452 I assume that's somehow related to being cast over jacketed, I haven't gotten too into that since my range doesn't allow non-jacketed.
