I need help finding a load for my 41 Mag Blackhawk shooting a 275 gr. Mt Baldy Keith style bullet. It does not have a gas check and I would like something not too stout so my son will be able to shoot it also, so I need to keep the velocity reasonable. Also Santa is out of cash so I need to use the powders on hand so here are the choices: H110, H4227, Titegroup, and Trail Boss. Suggestions?
