I've owned both and prefer the 300. Better ballistics, I've shot everthing from red fox, coyotes, deer, elk, bears etc..Doesn't ruin tht animals like my 7mag did. Don't notice the kick except at the range. I shoot a Ruger M77, stainless. I love the gun, light-weight, easy to clean and whatever I point it at dies. Had a Browning Bar 7mag, that I loved too, till I got the 300.
