[QUOTE="44-40, post: 2848395, member: 126985"] I can get 3 down in the mag and one in the chamber in 350 mag but the 300 WSM has a slightly larger dia body at .555" vs .532" for the belt. That could be fixed with a .060 Spacer. I modified the magazine, by reforming it, thinning metal front and back and extending it mostly forward, not much room going back, because of the trigger housing, then mill a small notch, & polish feed ramp...it requires a little gunsmithing, and metal work, use all available space. I usually modify the bolt stop, but don't remember if I did on the model 7 ...Feeds great. Adjusted the Remington trigger to 2 lbs. Use whatever action ya like, or are comfortable with...I had a model 7 in a caliber I like, so I improved upon it, at no cost but my time. I am a retired machinist with precision metal lathes and a Bridgeport mill...so it's a little easier for me. Most every rifle I own has some sort of personal modification done. The 4.020" cartridges for the Rem 300 RUM action, which was a little more involved, you really should have a milling machine for milling the rear bridge, with a sharp carbide endmill, with the action indicated in to follow orginial factory lines, and radius. It makes a big difference in its performance with 250 Atips, 2985 fps from a 26" barrel. If ya want more performance, better functionality, or beauty, modify it to your tastes. [/QUOTE]
