Ive got a 300wm Hart s/s barrel in remington sendero contour, 1 in 10 twist and a holland qd muzzle brake
on it. Ive got 87 rounds through the barrel and am not real fond of the cartridge. I wanted a 7mm but my gunsmith talked me into a 300 wm. Just not what I wanted so I am going to do what I origanally wanted.
