Does the feed ramp of my SA R700 receiver need to be relieved to use the extra length available in the Seekins DBM 308 magazines?
I have an incoming trade that I am hoping to use the extra length on to get the most out of my 7-08 with 162 Amax's adn may as well relieve that area now while the stock's off if anyone knows how much needs to come off.......
