Right, the real difference is the shorter COAL which slightly changes the load data.
My 20� 356 will push the 200-grain bullets above 2,350 fprs using Alliant Reloder 10.
The 22� Savage 99 will beat that by 100 fps or a bit more due to the longer COAL and barrel..
The Marlin 356 will cycle and extract the rimless 358 loaded to a COAL of 2.550�. There was an article and a lot of �to-do� about a Jim Carmichael article on the 356 Rimless a few years ago - the 35 Remington re-chambered to 358 Winchester and loaded as the 356.
The Winchester Model 94AE has trouble with rimless cartridges as the cartridge stop is a bit low. With two or more cartridges in the magazine tube the second cartridge will jump the cartridge stop and come under the lifter tying up the action. The cartridge stop could be re-worked but there is no need. If the 356 brass supply ever dries up it can be formed from 444 Marlin with no difficulty.
