I was thinking about what would be good for 600 and 1000 yard prone matches, and those big 338 bullets going slow still have very low wind drift. Sights have plenty of elevation, and you can always get an angled base, so scope elevation isn't a problem either. I was thinking a 338-08 Ackley might spit out the 300 grain SMK @ 2100 fps. What about the 338-06 Ackley? 2300 fps? Recoil would be pretty low in a heavy match rifle. Even at 2000 fps, the 300 grain SMK beats all 22 calibers at 223 velocities, and some slower 6mm's. At 2300 fps it beats all 6mm's and 22's, and would have pretty much endless barrel life. In a 15 lb gun your recoil is about 15 and 17 ft lbs, respectively. Is this idea feasible, or should I just get the standard 223 and be done with it? A little case with a big 300 grain bullet seated way out there might draw some attention!
