44 Mag in 444....no way!

Shooting a 44Mag bullet in a 444Marlin is a definite mistake. The casehead specs are different, .457" vs .471". The diameter of the 444 just ahead of the rim is larger than the 44 Mag and the 44 Mag case will either swell to fill the space or rupture. There is no support around the case and the results are always bad; the hotter the load, the worse the results. If you're not concerned about high pressure gas at 36kpsi blasting past the ruptured case and thru the firing pin channel and breech at you, take your chances.
