Thread: Another 375 DCM

I fire formed some brass for this today & took it to the range to form the brass to get some dies made.



It was interesting having to aim way low to hit the target with the Leupold on top of the 60 moa rail.



It has a Barnard P-Chey, Bartlein barrel, T5 Terminator Muzzle Brake in a temporary McMillan stock



Shots 10-12 with the 425 CEBs went pretty good, the customer is limited to ADI 2218, the Jamison brass isn't as tough as the Bertram.



It will be very interesting to see how it goes beyond 3.5-4.5K

In for longrange results

Yes it will be interesting, I don't expect to see any results this side of Xmas though.

Cheytac is the parent case.

I have reamers & brass for 375 Rum , standard magnum bolt face as well as 375 & 380 Terminator, Lapua mag bolt face.

Recoil gets pretty interesting in a light weight rifle.

This one is very interesting

Shit Cheytac is awesome is DCM getting better results, was thinking of using my spare P14 action but wonder if it would handle it?

The DCM is an improved Cheytac, which will be way too big for a P14 action.

Well he made it

Bloody small target to be fair 610mm square, tiny 1/2 moa....@ 4K metres



Plenty of near misses

The bullet flight time is comical

Yeah, completly nuts......

Its a sister rifle to the one I used at Tobys shoot.

Hey Greg , why not going with a shorten 50 bmg case necked down to 375 or 408? Making kind of a shorter column BR round?

Its been done a few times, the 416 Barrett is a great parent case, but having a slow enough powder & igniting it nicely is a drama with the big 50 primers.

Also you need a big/huge action & barrel for the 50 case.

Took the Sister rifle & its Sister to the range in the weekend.

Its the first time I've shot it for accuracy since last years Toby shoot, used the left over 450 grain CEB ammo, still shoots



The Sister rifle shoots pretty well to be fair with very few rounds down the tube.



Will be interesting to see what the real BC of the 361 Flatline bullet is, was hopeing to test it at distance before next weekend but haven't had the chance so next weekend it is
