my remington 7400 30-06 has a detachable magazine and i like it alot the magazine is always in the gun when i get to the woods i pop it out and load it then toss it back in and when im leaving drop it out remove the ammo and put the mag. back in never had a single rattle its my first semi auto rifle and im very happy and its much easier to load and unload over my marlin 336w 30-30 you have to basiclly chamber every round to unload that thing and with the exposed hammer it worried me sometimes even with the safety on so im happy with the magazine on the 30-06
