The 300 has some fairly moderate recoil. 50+ rounds is gonna leave you sore, if not bruised. It's parent case is the 375 H&H mag, which is a dangerous game cartridge. This is a cartridge that shoots 308 weight bullets at 223 velocities. It has the punch to easily take out anything in this hemisphere. Take the energy you get out of your average 308 Winchester (~2650 ft-lb) and add the energy from a 223 Remington (~1280 ft-lb); now you're right in the ballpark of where the 300 Win Mag sits on the energy scale (about 3900-4000 ft-lb).
Recoil energy on the 300 is about 30% greater than the 30-06. I've heard it ranks about even with shooting a 12 gauge pump gun with 1 oz slugs. Looking in a reloading manual shows that 300 Win Mag requires special attention to crimping and bullet selection to prevent the bullet from moving with respect to the case on rounds in the magazine when the cartridge in the chamber is fired. We usually only have to do this when it's expected that the rifle is going to move around a lot, like in semi-auto rifles or with big bruisers that have lots of recoil.
Just some food for thought. If it were me, I'd have to have a reason for 300 Win Mag. On this continent, there ain't a whole helluva lot you can't to with a 270 or a 308 that you can with a 300.
