Sorry, don't own a 300 mag Ruger, but do own a Hawkeye 257 Roberts. Nice rifle and pretty much agree with R-bolt's post. I don't hunt, just shoot paper so getting a decent group out of a rifle is my goal. Lightened the trigger pull in mine and free floated the barrel, which helped its accuracy. While it doesn't match accuracy of my old Ruger 77 tang safety rifle, I sure wouldn't hesitate using it for hunting.
