I feel rather humbled by 9.3 as the only thing I've ever used my Trapper for is to punch holes in paper. Being a keen handloader I've tried everything in it from a round ball to a sized down Lee 45/70 bullet weighing 340 grs. They all shoot amazingly well although my favourite is a 185 gr obsolete Lyman bullet for the 45 ACP (452389) over 11 grs of Unique which shoots tiny groups. The hottest I've gone is a Saeco 300 gr SWC over 21 grs of H110 but that one is hard on the gun.

In my Model 25 I used to shoot an old 240 gr Lee full WC over Green Dot and shot some good scores with it. The WC bullet took up a lot of the case capacity and it shot well at 800 fps over moderate loads.
