The 6mm PPC and 300 Whisper are 2 cartridges based on the 7.62x39 with a blown shoulder. ASI in CO offer custom barrels for the Mini 30. The 6mm is supposed to have comparable ballistics to the 243 Winchester.
Magnum Mini?
Is it possible to ream the chamber of the Mini-30 to a more powerful .308 cartridge? I Know that the magazine length and head diameter are the limiting factors so I was specifically thinking in terms of a 7.62x39 improved for possibly 200 or so more fps. Anyone ever heard of this being attempted?

Check out www.quarterbore.com for info on the 300 Whisper. It was developed for silenced guns but can be loaded with light bullets for higher velocity. It can be chambered in rifles with exsisting 223 barrels.
Another thought is to use Cor-Bon ammo in 7.62x39. It is hotter than standard ammo.
