The sabots I've been shooting are, Hornady 158gr JHP/XTP and TC
Break-a-way 180gr JHP. The TC's seem to load a little better than
the Hornadys. I've bought some Ball-ets, but haven't had a chance
to try them out yet. Just got'em in a few days ago. I've tried round
balls, but I think the patches I have are to thick. The starter scores
the ball when tring to drive it in the bore.

I bought the gun back in 1989 or 1990, and probably shot around
175 loads altogetherthrough it. The powder I've been shooting is
as old as the gun. (Pyrodex RS and Pyrodex P) But it's been sealed
and stored in my gun cabinet over the years. Haven't had any misfires
with it, but I kinda wandered if there may be pressure changes due to
the old powder. I don't know if powder gets less potent with age or not.
Looks ok and smells ok, but sometimes has small clumps in it. I can barely
touch it with my finger and it will crumble apart.

I should have mention this earlier in the post, but I just thought of it as I
was reading your reply. I was cleaning the gun a few years back with one
of those aluminum cleaning rods and nylon brush. Well, the brush hit bottom
and stuck the rod pulled apart halfway down the barrel. After about 2 weeks
of working with a nylon string with a loop and slip knot I finally with drew
the rod. Needless to say the bore had rusted. I got back on it with a bronze
brush and ramrod and give it a good scrubbing. The accuracy varied a
little then, but seemed to comeback after a few shots and cleanings.

I really appreciate the bore light tip, I'm going to trythat out tonight.
