Hi Guys,

I'm going to have a .375 Cheytac built and I'm told chambering in .375 DCM (.375 CT Improved) is the way to go.

Can anyone here please tell me what the chambering difference is between .375 Cheytac and .375 DCM?

What advantages will I get from chambering in .375 DCM?
Does it offer larger case capacity for more powder?

Any other info would be greatly appreciated.

Thanks.

Tagging in, I'm in the same boat and hope someone with some experience with these cartridges can shed some light
 
who around here has a 375 dcm reamer. I know from what I have read if you are going to go 408 based anything it is worth improving it.
 
From what I've gathered so far, finding the DCM reamer is not going to be
easy. But, I was told that the .375 Snipetac would be very close to the DCM
chambering. Giving one the "improved CT" chamber.

How much of an improvement is yet to be determined by myself. I don't know if this
is really something that needs to be pursued for my build. One thing is getting a
custom die set for an "improved CT" chamber would also be challenging from what
I understand.

Having to fire form 5 cases, neck size only (2X) and then send them in after the last time firing to have a custom resizing die made. You'd have to have at least a neck sizing die and a seater die just to get started to make the custom die set as I see it.

Still weighing all the factors and seeking more info before I make a decision.

Do you know the exact differences in the DCM and the Snipetac?
 
the dcm, snipetac, and allen magnum are all about the same I think you are only talking 50 or 100 fps max from fastest to slowest. you can't really improve much beyond these and still have good extraction.
 
I have built a few straight 375 Chey Tac rifles and they are a pleasure. Meaning readily available factory brass, dies, bullets or ammo if you want it. Forming brass will be expensive quick with this big of cartridge. It is also plenty powerful enough to challenge any shooter at distance. 100 to 200 feet per second would be very hard to detect shooting side by side.

I have a new one in process. I use almost exclusively Bartlein barrels whenever I get to pick what to use. If we all ordered barrels from Bartlein at the same time they might be convinced to make some .375 barrels. Right now they refuse, stating there is not enough demand. Brian actually said if the 338 won't do it to call in an air strike. I told him, this is the air strike, and he said no really, call in an airstrike. We don't have business shooting as far as a 375 can shoot. When someone wants to be, "The man" this or our 338 CT Max is what we recommend. After super max improving the 338 Chey Tac the 375 Chey Tac is still more fun to own. It hit's noticeably harder.
 
If Rockcreek can't come up with me a barrel in the next few months I'd be in on a group buy for a Bartlin gain twist in 375.
 
Kiwi Greg is a member here he has built a few of these I'm pretty sure

there is already a group buy that I think would still accept the orders the more guys we can get the better chance of getting these barrels made.
