Went over to our farm this morning to shoot the .300 Win Mag to see how it does. Its a remington 770( yes I know its a cheap remington, but I like it, and for what I paid for the rifle it does all I need it to do without spending a ton of money) This is my first magnum caliber rifle and yes it kicks like a mule and yes it was fun to shoot,lol. Me and my brother made a 250yd range to shoot on. I will say the limiting factor to my rifle is by far the scope. Its a crappy one that came with the rifle. The reasoning by not such tight groups. But all in all, for the first time shooting this rifle im pretty pleased with it. I used Winchester 150gr Power-Point. But did have a few tight groups noted by the arrows. I just need some more practice and a better scope.
