Mine has the buckhorn sight, which while authentic I don't really care for. I want to modify it or replace it with a flat topped rear sight, possibly a ladder type. I'm also looking into replacing the front sight with a bead that would be more visible in the woods, because I'd like to take it deer hunting.
Last night I loaded up 50 rounds of .44 WCF with 2.2cc of Goex 3Fg. The previous night I'd loaded 50 with 35 grains by volume of Swiss 3Fg. (2.2cc is about 35 grains by volume of BP. It's a lot faster to scoop the powder out of a bowl using a 2.2cc Lee dipper than by pouring each charge into a measure.)
The bullets are 200 grain RNFP from cowboybullets.com, from a 100 round sample pack (they actually sent me 105). I'm hoping they carry enough lube to prevent fouling out towards the muzzle.
BTW, where did you get the load data for Unique? That seems to be a little warmer than current data that I've been able to find.
