WOULD BE INTERESTED IN KNOWING HOW LONG ANYONE FEELS THEY CAN USE MANGUM BRASS, 41MAG ETC., AND STILL KEEP HUNTING ACCURACY. TO ME THIS MEANS NO BIGGER GROUPS THAN 5" AT FIFTY YARDS.

Shoot it until the necks split, you won't notice a loss of accuracy.

Just like KevinNY says, but you may check also the brass lenght if it is not too long. If it is, you must turn in into correct lenght. Nothing difficoult.

Also, nickel plated brass tends to be more brittle than un-plated brass, so nickel cases usually crack and split before plain brass cases.

The one thing to remember, the more you bell and crimp your brass, the shorter its lifespan.

TCLouis is correct,the less you work your brass the longer it will last! Shooting .38 target loads over and over and moving the brass very little it would last and last. If you are shooting jacketed bullets and using a taper crimp the brass will last a lot longer. With real hot loads I use nickled brass so after long periods of time I don't mix then with the regular hot loads. Killed 3 bear and a elk with a 44 mag. Good luck
