Thinking about doing a long thought of 458 Winchester project. Re-barrel a Mark II 300 Winchester to 458 Winchester. Use the 416 Ruger barrel contour at a 22" length. Prospect donor rifle seems to feed the 458's fine.
That'll work LDM, i was wondering what kind of a 500 yard all game killer we could come up with if i could talk JWP into letting JES 458 bore his CZ 416 Rigby, talk about an ass kicker 450 Rigby Magnum with 404gr Hammers at 2950 fps and COL of 3.650 inch LOL!
