Cheytac or sniptac for R8

Post by sav338 » Wed Jun 15, 2016 4:13 am

This is from the right field and might be asking too much from a light rife but.
Has anyone built a 375 cheytac or 338 sniptac barrel for the R8 platform ?
Will the action cope or just come apart ?
And then the issue of a bolt head.
Cheers
:D :shock: :lol:

Doubt it, but with a lapua theres not much more you need.

A lapua bored out to 338/378 wby would be a mean tacticool that stupid state governments won't ban.

Both the 375 cheytac & 338 snipetac are built off a 408 Cheyenne Tactical ( cheytac) action . The Parent case is a 505 Gibbs which is a different case to the 500 Jeffery. If both the cheytac & snipetac had been built off the 500 Jeffery it could be a different story. But the pure grunt of the 375 cheytac would really belt the sh#t out of lite R8. Would most likely let someone I didn't like shoot a few times first I think.

I see that Thomas Haughland has a custom barrel on one of his spent 6.5x284 barrel receivers. Albeit, it's a .22 cal. So someone is doing machine work that has made this proposition successful.
At the end of the day the action on the R8 is capable of handling a minimum 68,000 + psi... I believe they're proof tested well beyond 100k psi..?
Unless you exceed that by some massive margin I couldn't see why the Action couldn't handle the pressure of a Cheytac.

Bolt thrust might be an issue given the volume of gas that those case powder caoacity's could produce and the extended duration of peak chamber pressure might flog the action a little! It'd probably need a brake too... A BIG one!
She'd be a violent recoiler in a light hunting package!

I agree with deerhunter338mag... Have a "friend" pull the trigger first and stand back... Way back haha!

A local lad over my way is playing with a .375ct improved, you can see his vids on YouTube, big case!

There's a guy in NZ that's making 338 Edge barrels out of 375 h/h barrels for the R93. I sold my 375 H/H barrel if I didn't I would seriously look in to that.

Yeah it's not that hard it's done by Hardy engineering. You can use any cal as a donor. They just cut the old barrel off an existing receiver, thread the receiver and barrel and screw it together. Pretty simple really. They have done plenty of them over the years. Also means you can unscrew barrel when shot out. You don't specially need a magnum type barrel as a donor, but it's a good idea as its already got the MA stamped on it.

Mate is doing a 280ia and the same guy that's got the edge has a 260 REM also.

It's a sacrifice I would say as I have never heard of a Blaser shot out
Your looking at around $1700NZD to get it done as well. That's blued and they make there own barrels for them. If it's a cal you really want and they don't make it, well it worth it.

Oh right, so basically the doner gets turned into just a barrel adapter, like you can get for the Sauers?

There was me wondering how the hell they did a "reverse re-bore" and shrink the hole down! :)

That's it Jeff. And when you think about it, you can still make it into a switch barrel set up as well. Just have a few barrels made in wild cat cals and get yourself the barrel jig to remove and install different barrels.

I only know of it been done on the R93 but wouldn't be hard to do the same thing on the R8 as well. Your 338lap barrel could be 338lap, 338lap imp and 375 sledgehammer.

It's endless what you can do I guess, it's just only money :lol:
