[QUOTE="sable tireur, post: 1660331, member: 27307"] While the bolt face is the same diameter as the standard belted magnum cartridges, the body diameters are different with the RUM body being decidedly larger in diameter. The Remington M700 action will handle the RUM cartridge ([B]Remington[/B] Ultra Magnum), it's important to pay attention to the width of the opening in between the action rails. Action rails are cut to allow the cartridge to feed from the box by the follower up into the feed ramp. But there has to be enough material left to hold the remaining cartridges down. You may need to adjust the feed ramp as well. [B].375 RUM[/B] [ATTACH=full]138992[/ATTACH] The RUM cartridges, like the WSM cartridges, require the magazine box with the triangular windows cut into them. Getting some cartridges to feed reliably is both skill and art.
