: Using Large rifle primers in 45 ACP?

Went to my local shop and they, like everyone else, have no large pistol primers. They said that large rifle primers can be used as they are the same dimension other than the cup being made out of thicker sheet stock. This was said to possibly cause light FP strikes if the FP spring is not up to it.

These guys are old school. Brothers in their 80's. Running the family business that has been around for generations. They both smoke in the store in defiance of the NC smoking ban and the reloading powders they have for sale. I figure if they have not blown themselves up yet they may have a good idea. :laughing:

Visually the two primers look about the same OD but definitely thicker cup. I have yet to put a micrometer to them. Anyone done it? Any drawbacks? These would be going into a Dan Wesson CBOB or PM7.

I have a fair amount of large rifle primers that I bought in anticipation of reloading 308. But I shoot my 1911 much more. Down to hundreds:eek: If no one says I'll blow my face off I am going to load up some empty cases first to check the Firing pin strikes and if they work I'll load up a run and see how they do.

What say you?

Go for it. If you don't report back, I'll assume you've blown your face off.

Actually, I don't reload and have no fawking clue. Don't take my advice.

I think we have covered this before (I know I have also read it on SASS wire).
IIRC, the rifle primers are slightly (almost undetectably) taller than pistol primers.

I know in some wheel guns, the "high primer" will hang up.
Others have stated they used them with no problems.

I'll see if I can find a thread with more info instead of me going by memory.

You can get away with using SR in place of SP, but don't try using LR in place of LP. :)

Weeeeell drat.

Thanks for looking that up Zuk. I missed it the first time.

Now for my next post " Can I trim Large Rifle primers with my beltsander" :laughing:

Anyone want to trade a 1000 Large pistol primers for 1000 winchester Large rifle? FTF in Central NC?

Just put the mic to the different primer
s

LR primers are def 4 thou thicker than the Large pistol. Surprisingly it is not the cup that makes it so. The anvil sits proud of the open cup. I had not noticed that before. Guess I'll be reloading rifle next;)
