I have a 338 win mag in Remy 700 sitting in the corner that is collecting dust. I know these are not speed demons, but what would happen with a 300 grain Berger at like 2400 FPS? I ran the numbers quick, and it looks like the same energy at 1000 as my 300RUM with 210's. Anyone try this before? Results? Besides have to dial a few more MOA, can anyone think of any issues I may have? Any expansion issues at the low velocities with the 300 Bergers? This is being built as a hunting rifle, light enough to pack to 10,000 ft. I ordered an HS Precision for it that should be here next week, and will probably do a 20 MOA Rail. I figure if I dont like it, a new tube in 338 Edge would fit nicely.
