I have been reading old posts about the AR chamberings. I am interested in chambering a M70 Stainless in either .375 or .416 AR. Who has the reamers? Also, what makes the .375 different from the .375 Dakota? Are dies available or do they have to be custom made?

We have the 416, 458, and 470 AR. The 375 is a next year deliverable, if there's enough interest and advantage to the round vs the dakota. SO, the 375 isn't there to compare to the dakotas.

Since this is from R.U.M. cases, the case price is cheap.

CH4D has already made my 470 AR dies, and will make the others. I am sending fireformed cases for exact to case "realized" to drawings.

Please contact me in PM for the gunsmith. Of course the gunsmithing charges will vary on the work desired. Stainless is no issue at all.

The 416, with a 26" barrel, can easily hit 2500 with a 400gr bullet as the case is larger than the 416 rem in capacity.

The overall rounds are 3.35" long, and fit in standard 338 winmag length actions with ease.
