Have never been without a 41 Mag since "76" It was the cartridge that prompted me to purchase reloading equipment.That has developed into loading 27 different cartridges.
I am a bullet caster as well I only did big bullets for big buffalo rifles now I have 2 custom 41 Mag molds.Never enjoyed my revolvers more.The .41 Mag is a splendid cartridge.When the big "hoard" was occuring .41 Mag componets were available when you could not smell a componet for .357 or .44 Mag.
It is worthy enough that S&W currently catalogs 3 configurations of the cartridge in the Mdl.57 Classic and Mdl. 58 and the Mdl. 657.The .41 Mag is the only reason I have bought S&W revolvers because Colt never chambered a revolver in .41 Mag,shame on them!
