Deepening primer pockets?

[cruddymutt]

Having a hard time finding 455 Webley brass at the moment. Ive been reading I can make brass from either 45 Colt or 45ar. Both require thinning the rim. Now I know that thinning from the case mouth side would be better but I do not have access to a lathe. This leaves thinning the rim from the bottom which will require deepening the primer pockets. What tool do I need to do that. A primer pocket uniformer?

That might work. I'd just get the correct brass. Graf's normally has it.

Yes, a primer pocket uniformer is what you want.

You don't need a lathe, a drill press or even a drill if ur hard up can work. Just get a dowel the correct thickness to fit inside the case and flush to the top of the case, chuck it up and CAREFULLY use a small file on the top of the rim. Done and done. Just be careful and light pressure is all that's needed.

Use a Large Rifle uniformer as it cuts deeper than Large Pistol. Sinclair makes a nice carbide one that cuts easier than the high speed steel garbage sold by most outfits.

The cutters on my RCBS uniformers are depth adjustable with a set screw. Might be wise to use a suitable cutting lube for brass.

Spencerhut, Grafs doesn't even list it in their catalog. Im learning this stuff is made in pretty limited runs. I have "in stock alerts" set up all over so maybe I will get lucky.
All is not lost. I found 2 pieces of brass in my weird brass bin and a friend says he has 2 also. Trying to look at this from all angles. Thanks everyone.

I deepen my 45 colt brass for rifle primers (don't ask, but if you have to, my "frugalness" likes component consolidation, and now 100% of my reloading uses only one kind of primer), and I used a primer pocket uniformer chucked into a drill for 500 pcs of brass.

It gets tedious, (coming from a guy who can trim and chamfer 500 pcs of brass in one shot without stopping) so I did it over a period of a couple days. Furthermore, I found that using the cutter left pockets tight (for the larger primer), so the first go around I primed on the press rather than the hand primer. And will uniform a second time after a few loadings to ream the pocket out just that little bit more for perfection.

But it works just dandy with a cordless drill and time.

Yup I saw these. I'm reading they are cut down from 45 Colt. You saw that price though right?

[Whiterabbit]

Compared to $460 weatherby, that's a deal.

I hear you though. I'd still be making my own. On my lathe. By cutting the back off then deepening the primer pocket.

You know, I bet you could shave the back by getting real clever with a drill press. I can think of some fancy footwork with a HSS tool clamped in a block and hand driven through a case chucked in the drill.

I just tried some test pieces of 44 Mag (i don't have any 45 Colt)on my drill press using a file and we have success! I cut them to length and they chamber in the cylinder, the revolver locks, and the cylinder turns. Rim thickness for 455 is .035, mine are .040. I did this as a proof of concept type test. Now to get some 45 Colt and a uniformer.

You should measure your actual GUN to see what rim thickness it will tolerate.
Even though the "spec" might be 0.0XX, you might find that your gun might tolerate 0.0XX +0.008" or even more and that MIGHT put you into the thickness range of unmodified 45 colt...

You could also consider letting your cylinder forward to tighten up the cylinder gap some so you can run unmodified 45 colt case rims.
Might be easier to modify the gun once than every case if you want to have a few hundred cases to shoot...

The endshake would be excessive.

The endshake would be excessive.

Not with cases in the cylinder.
