Man this is a rampant rumor..

It's on the books for consideration next year... it will allow the use of straight walled pistol cartridges in a rifle.. like .357, .44mag, ect.. I don't think all of the particulars have been completely worked out... but according to the COs that I've talked to.. it's pretty much a done deal.

As for flatlanders... these cartridges have about the sameor less rangethan a rifled slug gun.. and less than a modern muzzleloader.
