Loads for .41 Magnum:
(Note: These are near maximum loads, you should use 10% less to start.)
(See note on Powders below or read all about various Powders.)
Bullets are .410″ for jacketed and .411″ for lead in diameter. Due to different barrel lengths, type of bullet, seating depth, primer type and other factors, you may not get near the FPS charted. It is just a guide and the reason you should start under these charges and work up.

Discussion: Only one LEAD bullet is show above. If you want to use lead, pick one of the jacketed bullets and deduct .3 to .5 grains for a guide. Universal, Clays and HS6 are from Hodgdon and similar to Bullseye and Unique. HS6 is slowest of the group (Similar to 2400) and takes quite a bit more powder. Respectively are No.2 and No.5 from Accurate.
A bullet with a copper gas check or copper plating is best for INDOOR ranges to keep lead vapors out of the air.
