| I'm not sure. I have a 7mm Int-R, which is the 30-30 necked down to 7mm, and the case blown out, I can't remember the shoulder angle. 140 gr bullets at 2200 fps out of a 14" Contender. If you use 375 Win brass, I'm told you can get another 100 fps, but I've never tried it. I don't know about case capacity on this one (I'm not at home, so I can't just check it). The 7-30 Waters is supposed to be good for another 100 fps yet, as I don't own one, I don't know for sure. FWIW - Dan |

| Looking at a case diagram, the 7-30 waters has a rim to shoulder base lenglth of 1.586" and shoulder diam. of .399" with a slightly steeper shoulder. The 30-30 has a rim to shoulder base of 1.441" and shoulder diam. of .401" I would think the 30-30AI has just as much capacity with that blown out and moved forward shoulder as the 7mm waters. Anyway, the .30-30AI is said to give 200 to 300 ft/sec more velocity at standard .30-30 pressures. |
