Hunted all last year with my Christensen Arms Classic with their Titanium Side-Baffle break in 33 Nosler. It's nickname is The Hand of God because it will reach out and strike anything down. With that setup I can watch hits through my scope and recoil is almost non existent. I own 2 300 win mags, for big game I grab the 33 Nosler every time. If you look at ft lbs of energy the 33 Nosler carries compared to the 300 win mag its not even fair.
Load development was a breeze, highly accurate. And you won't have to run the extra step of a collet die like you do on the belted mags. 300 win mag is an excellent cartridge and has taken more than its fair share of big game, but there is no comparison to a bigger, harder hitting 338.
