Re: 115 D -TAC encounter with a steel plate at 1 mile
I've had some requests for more info on this cartridge so I thought I would add this to the post
so here it is....
The .243WSSM Rouge is a .243 Winchester Super Short Magnum improved 37 degrees with .009 body taper. Then the necks are turned to .270 for .272 reamer,then it is throated for 115-D-TAC's.
I'm using Winchester brass but I believe Federal also offers brass. My case prep involves sorting out cases by weight and keeping everything within 1 gr., reaming inside flash hole, reaming primer pocket,turning necks and then anealing neck and shoulder
I have not messed around with many loads.
Here is the load I am using:
Federal GM 210 primer
47 grs.of reloader 22
115 D-TAC's .005 into lands
muzzle velocity 3175 fps.
reloading dies...I'm using Hornady custom dimention .243WSSM seating die and a bushing neck die made with the same reamer as the chamber was cut with and accepts Redding bushings.
As far as B.C of the bullet my program didn't have the 115 D-TAC's so I entered the B.C of the 115 Berger which is .597 and it followed all the way out to 1 mile so the B.C is at least that of what Sierra states.Visable pressure basically non-existant,primers maybe starting to flatten by the edges,but is almost unnoticable
The barrel is a Broughton 5C 1 in 7 twist and 31" in length. I believe you would see little to nothing in velocity drop at 28". The barrel is long enough to reset and rechamber twice. As far as accuracy I am consistantly shooting .330 MOA out to 600 yds. off the bi-pod (in good conditions)and have shot .330MOA out to 1040 yds. So this cartridge is showing serious promise, I just wish there was better brass available.
P.S froma 600 yd zero there is 12.5 MOA up to 1000
without God their is no hope for this country
