Anybody have any hands on experience with the ill fated 10mm Magnum cartridge that was offered briefly in the AMT AutoMag? I'm in the mood for a new Contender Carbine barrel and was checking Bullberry's caliber list and saw the 10mm Mag was offered. Humm, that might make an interesting toy. It's a dead duck commercially but Starline still offers brass so somebody must be shooting it in something. From what I recall, the cartridge offered impressive velocity from a handgun so it really ought to shine from a carbine length tube. Anybody played with the cartridge? Who makes dies? Huntington doesn't list them although I'm sure they'll do them on special order. Thoughts?
