45 Primer Problems.


December 5, 2008, 10:26 AM
I am using once fired mixed brass that has been deprimed and tumbled clean. It has been resized and is in the process of being primed. My primers are just half a hair from being flush and I can't get them to seat any deeper. I am hand priming them in the same Lee hand primer that has done 9k others in 9mm, 38, 357, 223, and 308 with nary a problem. I am using CCI300 primers. I stopped at about 50 rds and maybe 5 or so seated flush. This brass was fired from a new Kimber and a new Sig recently, so I know the history of the brass. It was all factory loaded, not reloaded. It will be fired out of a tuned SA and an XD if I can get it loaded safely. I have been loading for a few years and am just starting 45 which should be simple at this point. What am I doing wrong???:banghead::banghead::banghead:

Even when used in a 550B press, I find CCI 300/350/200/250 primers pretty dang hard to seat fully in a lot of brands of brass, while other brands much easier. CCI 500's seat harder for me than say Win, Rem or Fed SPP. Note, my CCI 300's are from my last big buy of about 12 years ago, and can't comment on newer made ones.

I always used CCI's for cases with less than tight pockets as a way to salvage the otherwise good brass for more loadings. Obviously very loose pockets went to the brass fairy.

I've loaded 6k this year and every one has been a CCI primer. CCI 41, 34, and 500's. Now today 300's and problems. :(

Change to Federal, Winchester, Remington or MagTech and the problem will go away. You're running into the problem of mechanical advantage with the hand primer and hard primers. You just can't get the leverage with it that you can on a press.

The other brands will seat easier and you'll be able to use your hand primer with those just fine.

Hope this helps.

I use those primers all the time with the Lee Auto Prime and no problems. I notice most of the other rounds you've been loading use small primers. When you converted to large primers for the .45 ACP did you change the Auto Prime to the large tray and to the large primer pin? Might be worth checking.

Sure did, basically set it up to prime 308. Large tray and pin and 308 shell holder.

Fred, this is what I have and really need to make this work. I am not able to change primers at this time and just can't imagine that I am the only one having problems getting CCI 300's into 45 casings with a hand primer.

Maybe I'll have to wait a few weeks and get some different primers. :cuss::banghead::banghead:

I guess I would try another maybe different hand primer?:scrutiny:

Winchester primers. Used cci for years then a few years ago i had nothing but problems i tried everything. so i made the switch to winchester and i havent had a problem since the change.

How about a piece of "beageling tape" on top of the pin???? :what: It works, :D now I'm back to work. :cool: HEHEHEHEHE

I have had nothing but good luck with Winchester (WLP) primers, just ordered another 10K of Winchester primers. I load .45ACP on a Dillon XL-650.

That's the right setup. It's a real mystery then. Should work. I've had 3 Autoprimes in the past 20 years, loaded over 30 thousand rounds, many of which were .45 ACP and AR, with all kinds of primers, including CCI, Rem ington, Winchester, and Federal (even though LEE warns against Federal). You might e-mail Lee and ask them for advice. Something's out of whack.

Any chance you got hold of some GI or "CleanRange" brass with crimped primer pockets?

Nope, it is mostly rem, fed, & win. All bought from wally world by some friends. I don't own a 45, I can do everything I need to with a 9mm. :neener:

Sometimes it takes a little extra effort to seat the primer to the bottom of the pocket with new or once fired brass. The only time I've had high primers was when I accidentally grabbed a box of large rifle primers instead of large pistol.
