I have a 15" MGM barrel, the Lee dies were the real only issue I had getting started Lee took care of it, brass is not impossible to find, I did find annealing a challenge at first but with my induction annealer and jig it is easy enough, Load data is sparse, Loading is not bad, Same ballistics as a 22 Hornet with out the fragileness of hornet brass, Being that it is a 15" barrel and rather awkward to carry and hunt with I am thinking of either having a barrel extension to make it a legal rifle barrel or cutting it to a more comfortable pistol length weight. It shoots every bit as accurately as any other 22 barrel I have, And it just looks cute too. LOL
