I've just got info about potential deal for BFR 50 AE and few hundred cases (brass). My problem is, I would like to have rimmed version so I can crimp bullet. As a matter of fact, I've got recently one mould 502-440-SWC (BTW, I designed bullet), like this:



What would be the most efficient way to make 50 AE brass rimmed? I was thinking about making some sort of snap ring on the lathe that will go in the groove. One of the steps is to shave back of cylinder (it's counter-bored I was told) to make space for the rim like on Ruger revolvers.

Please, consider that I am in Canada so to get 500 JRH cylinder is next to impossible.

Any help will be greatly appreciated. Thanks, Onty.

Hey, I like those bullets!

Can you just order a reamer? I understand the hassle of shipping firearms parts across the border, but would think that a reamer would be less trouble .... ?

If you have a lathe, seems you could cut down some 500 S&W brass, and make a slight counterbore at the back of each chamber. You'd still be able to use .50 AE in it, as well, if the chamber was not modified.

Just a thought.

Unfortunately, cannot be done, 50 AE case http://en.wikipedia.org/wiki/.50_Action_Express is (at the base) about .016 larger in dia than 500 S&W http://en.wikipedia.org/wiki/.500_S%26W_Magnum .

As for that 502-440-SWC bullet, or group buy just finished. If there is no problem with rules on this forum, I can put the link so you could see whole thread.

Sure, put a link. There are group buys here once in a while.

If the case head is larger than the .500 S&W, then it's larger than the JRH, too. So I'm afraid I don't have any further ideas.....

Would a .500 Linebaugh clean up the chamber?

According to Ammoguide, the .50 AE is .543" above the extractor groove. The .50 Alaskan is .548" above the rim. Starline suspended production but Buffalo Arms still has brass.

Here is the link for the GB for 502-440-SWC http://castboolits.gunloads.com/showthread.php?t=101236 .

Yes, 500 JRH has same head dia as 500S&W. As for 500 Linebaugh http://en.wikipedia.org/wiki/.500_Linebaugh , it will clear but this is .510 groove cartridge, not .500 as 50 AE.

Regarding 50 Alakan http://en.wikipedia.org/wiki/.50_Alaskan , same .510 groove dia but since this case is 2.100 long, there is a chance that when shortened on 1,285 length it will have bit more case thickness to fit .500 bullet. However, since it’s not regular product, I am reluctant to go this way, and brass from Buffalo Arms is $1.19 EACH.

Another solution is to see what is brass thickness on 348 Winchester when cut on 1.285 length.

Will see first what will happened with that deal. Thanks to all, Onty.

Here is a 50AE Rimmed based on a 500 S&W. It looks like they fudged some of the dimensions though.

Here is the 500 S&W

Last but not least the 50 Alaskan. If you want to trim all that brass.

Although in my opinion you'd be better off just going to 500 Linebaugh and chamber it to 1.285". Just for the sake of ease of finding and prepping brass.

I wish 500 Linebaugh can be used, however, this cartridge has .510 bullet dia.

50 AE is .500, that is the problem.

Right, but doesn't the .500 Linebaugh require inside neck reaming? What would happen if you didn't ream the necks, could they hold a .500 bullet then?

I suppose even if that worked, then you'd need a reamer with a custom .500 neck. So that's probably not easy or practical....

It all depends on how much money you want to spend. If you get a reamer ground to your spec then it rather simple. Have the reamer ground so that the neck is the same as the 50AE for .500" bullets and an overall length of 1.285". Simply cut the 500 Linebaugh brass down to 1.285" then run it through your 50AE sizing die. It would be about like using a small base sizing die for pistol cartridges. Or just have a sizing die made for the cartridge.

Of course you could just buy some 500 linebaugh brass and do some experimenting. Cut a few pieces down to size, size them and run through an expander and seat a bullet. Then you can checking dimensions and see what you need to do.
