Standard 375 Cheytac vs Snipetac

[Coercionist]

I have decided that I want to build a Cheytac sized rifle on a repeating action. For chamberings I was at one point looking at 37XC however, I want to shoot the heavier mono bullets from cutting edge and such so I want the extra power of the Cheytac case. My question is how much of a difference does improving the standard cheytac to a Snipetac actually give? It looks like it is a standard improvement via taking away some body taper and improving the shoulders to 35°. Besides adding velocity, would the Snipetac also help brass life since it would help stop case growth? and I've seen one of the reasons for the Snipetac is to shoot slightly higher than average cheytac loads but since it is an improved chamberings you would not have to push the brass as hard therefore increasing brass life with hot loads, but I could not find much load data comparing the two chamberings.

Overall I need a overview between 375 cheytac and Snipetac in order to see if improving The standard case would add a sufficient amount of velocity and possibly brass life.

An added benefit to the Snipetac is I would also like for this rifle to be a switch barrel rig, and therefore I could have another shorter barrel chambered in 338 Snipetac for closer ranges and cheaper bullets (besides I like the idea of throwing 300 grain OTM at the speed of light).

If you are serious about a switch barrel Snipetac in the near future send me a PM. I have an Long Rifles Inc built repeater, has a large switch barrel lug for fast barrel changes.

As of now I'm just looking into the logistics of it. And I also suffer from my chronic condition called left-handed syndrome. How do your forming loads cheytac loads compare to your full power Snipetac loads? Do you just have the 375 or also the 338?

I'm a lefty too, if a rifle is mostly fired prone (or at least not standing for hunting) I usually run a right bolt.
My forming loads are with a 350 Matchking at 2850 fps.
.375 only, that's why I built a 33XC.

Here are the logistics of it:
1. Expensive to build and shoot
2. Potential for extremely long wait times for build parts
3. Potentially long wait times for a quality builder to complete
4. Shortage of components, and goes through them fast (powder @ 150 grains per trigger pull)

Yeah That's to be expected. You can have fun without paying for it. Would you mind sharing your formed Snipetac load and barrel length?
