.375 Cheytac or .375 Snipetac

[critterskinner]

Which is better ballistic wise?

I heard some rumblings that cheytac`might be going out of business???
Don't know how true that is.

Even if Cheytac did go bellyup components would still be available through Jamison and other sources.

IMO,The extra FPS gained isn't worth the hassle of fire forming.

Not that I know much about either, but what I see I really love the 375 snipetac, maybe one of these days one will grace my gun room. If I were to win the lottery I am sure I would be on the FBI's most watched list for all the firearm power I would have.

There is not much gain in velocity between the standard case and the improved case, but there is much to gain in terms of efficiency, that far outweigh the "hassle" of fireforming if you start with the standard .375 or the .408 case.

I'm curious how so? No disrespect,just wondering.I only say this because I have a regular 375CT.The problem I find with the cartridge is the lack of suitable modern powders giving proper load density to achieve proper "efficiency".Even a max load of Retumbo (134 grains) behind a 350 Jamison is 1/4" below the shoulder.I'm assuming load density would be a worse problem on the improved case. Maybe I'm wrong?

I've had slight hangfires with R-25 which I feel is too fast of a powder for the 375CT and have had hangfires with some of the really slow 50 BMG powders.No problems with Retumbo,US-869(very temp sensitive),AA8700 which is no longer available.I think the 375CT case is already on the very edge of what a large rifle magnum primer will reliably ignite as is,let alone an improved version.

I enjoy wildcat and/or AI type cartridges myself.Of course the other cartridges are standard sized,6mmART40,30-375R,6x47L and others I've owned over the years.With them it's no problem finding the perfect powder and yes they are very efficient.


Thanks,

No disrespect taken at all...
Shot the .375-.408 quite a bit until I settled on the .338-.408. All my rifles are chambered for the improved cases. I never had an issue with load density in the .375. Retumbo was my powder of choice with the 350 SMK and the 215's. Never had any issues with hang fires with either the Retumbo or H50BMG. Most rifles were single digit ES.
Powder of choice with the .338-.408 improved case is H50BMG. I can fill the case with more powder and pick up the velocity, at the cost of accuracy. Personally, I have not had any issues with load density in either case.
