prof242 - make sure you shorten the tubes to behind the chokes for best shooting with RB's. Also, you'll find jeff Tanner in the UK will make any size you want. I'd go for a round ball mould same size as the bore. This will produce a hard ball a couple thou undersized. Wheel Weight alloy is all that necessary - nothing harder than that is needed for anything you'll be shooting with that gun - in N.A. or Africa for that matter.

Once the gun is aquired, shortened and sighted, the gun begins.

I just tested some pure lead, 1,600fps SR4756 loads in my Mossy 835 pump and cut a 1" hole for 3 shots. It does have iron sights and a rifled barrel. Next testing will be at 50, 75 and 100 yards - later this fall. 10 day rendezvous is coming up shortly.
