[QUOTE="CatShooter, post: 1489015, member: 7"] First belted cartridge was 1912, (375 H&H) and it was designed for the new fangled "Magazine Rifles" that Holland & Holland started making, cuz the flanged Nitro Express cases made for double rifles, would not feed reliably in Magazine rifles, and considering their use, that was a really badd problem. The forward to shoulder "headspace" on belted cartridges is STILL not critical... my 264 WM shoulders blow 0.039" (39 thou) forward on the first firing, but the belt headspace is 0.004" (4 thou). I neck size them and they last forever. [/QUOTE]
