I tried out a couple MSR's in .338ARC and I've got to say they've got some serious thump!
Hodgdon Powders list loads for bullets ranging from 165gr up to 300gr.
I loaded some 300gr Burgers at subsonic and some 185gr Hornady CX at approx 1,800fps. both shot touching groups at 25yds, the plan was 100yds but the Black Flies and Deer Files were tearing my ass up, so I packed it in....besides, it was already in the 90's
