Decapping .375 CheyTac as separate step

[DanGuy48]

Like the title says, I've decided I want to remove the primer as a separate step, not part of the resizing. I've not seen any tool for this, off-the-shelf hand tool or die. So I've decided to just drill a hole in my bench and fit a shell holder and punch it out that way. Before I do that, I just want to check here to see if anyone knows something I missed. This cartridge is unusually fat since it's almost identical to the .505 Gibbs. Thanks in advance for any info.

I dont know what dies your using but if you could thread your de-capping rod into your bullet seating die you could achieve this with your press. Hitting a de-capping rod isnt recommended since the de-capping pin is usually carbide and can be brittle.

Hmmm, my seating die won't work but maybe I could do the next best thing and get an inexpensive neck resizing die in .408 CheyTac and use it just for decapping.

I have de-primed my .408 based wildcats both ways, and actually prefer doing it in a single step just the way you mentioned. There's nothing wrong with doing it by hand, and it will actually allow you to keep tabs on the primer pocket before taking the other steps to re-size and anneal... I do not drag the size button through the necks either...

Yall do know RCBS makes universal depriming and decapping dies, right? They offer 2 different ones. They are .22-.25 cal & .27-.45 caliber. I have both and they work like a champ. I always deprime my brass before cleaning them, as a seperate step. It is always the first step I do, then I sonic clean, then tumble & polish, then reload. I find depriming first helps clean up the primer pockets alot better.

Don't think they'll work with the .408/.505 Gibbs case...

Redding has a large Universal Decapping die for 284 to 50 caliber cases with maximum case length of 3".

Yeah, I've got one brand new one, unused, if you want it. I thought the .50 might have been BMG .50 but apparently not. The CheyTac cartridge won't fit up into it. BTW, like the screen name. LOL.

Hey, we could meet at Brewer's Alley and chew the fat. J/K

Yeah, I'm 10-15 minutes from there. How do you know Frederick, your info says you're in NJ?

I spent six months in DC back in 2006 and wandered up to Frederick a few times. Seemed like a nice place to live.

I have an arbor press that I use to push the primer out with an expanding/decapping rod from a 7RM die. I use a metal "cap" with a hole in it and I place the 375 brass on top of this. I also use this setup to decap military crimped 50s.

Have just acquired a 375 cheyTac I was interested in the results of this post. After today I can share the successful methods I have found.

I use the Ch4h FL sizer body (.408) with a die stem from RCBS in 338
Lapua and the appropriate shell holder in the Rock Chucker- -Wa-La
Removed 50 spent primers in about 5 minutes. Now I can tumble the brass without primers- before resizing

You success may vary and this advice is worth every cent you paid for it.

Mighty Armory will make a decapping die that will accommodate the Cheytac cases. Give them a shout
