[QUOTE="Tyler Kemp, post: 216210, member: 6290"] This would be a switch barrel rig, with another barrel in 338 Edge for long range hunting. (and different bolt head) 2400 fps would raise recoil above 20 ft lbs. I could always do stuff to lower recoil, such as mercury recoil reducers, a gra-coil buttpad, but I'm not sure how fun it would be too shoot 88 rounds through in prone. To varminator, I was at a 600 yard match on Saturday and a guy was complaining about his 7mm-08 hurting him, but then others were shooting M1 Garands which aren't near as heavy as a match rifle and they shot very well. I heard people saying muzzle blast bothered them more than the recoil. But then again, it is about 15 lbs recoil, 50% than a 308 in the same weight gun. Here's some ballistics in a 10 MPH wind 338 300g SMK @ 2000 fps: 600 yards 25.6 MOA drop (doesn't really matter), 4.5 MOA windage 223 80g SMK @ 2850: 600 yards 14.4 Moa drop, 5.5 MOA windage (that's hot 223 load!) 243 107g SMK @ 2850: 600 yards 13 MOA drop, 4.1 MOA windage (it wins...so far) 338 300g SMK @ 2000fps: 1000 yards 55.7 MOA drop, 8.1 MOA windage 223 80g SMK @ 2850: 1000 yards 37.7 MOA drop, 11.4 MOA windage 243 107g SMK @ 2850: 1000 yards 30.9 MOA drop, 8.1 MOA windage (dangit!) But shoot that bullet a bit faster from a 338-06 Ackley and it wins by a good bit. The new Berger 338's have a BC a fair bit higher than the SMK's I hear... [/QUOTE]
