Doc is less reluctant to recommend the wildcat than I am. smile ...but we both like it best.

It isn't hard to do. below are COW formed Mahburn cases, recently made.

Recipe for COW: CCI large pistol primer.13 gr Alliant Bullseye. Fill to base of neck with RCBS dried corn husk tumbling media. Top off with a wad of tissue.

OR

Form and charge with 65-IMR4350-139 Hornady (or some other favorite 140 gr bullet works for other folks). This is a below max pressure load that is no toy and will show 3150 fps or so. You could easily hunt with this stuff.
