Thanks again for all the replies.

PM, That's a great set of data I'm saving those pics for sure. Much appreciated.

Tinker, I'm just trying to get off easy with the whole sabot thing. I guess we'll have to go with the mold and do it right. It's a hefty gun, but if 9 LB barrels are typical for a 3" gun than this one isn't even close. That's a lot of extra iron. I don't know much of anything about how much a rifle should weigh based on caliber except that dbl rifles are heavy and bore rifles heavier still. All I can reference is what little experience I have shooting big bores.

You'll have to coerce the Right Honourable DT/CC about pictures as the rifle is currently residing in the Cape Neddick Gun Hospital---Dr. Trevallion , Attending. Otherwise I'll see what I can do in a month or so when I'm back in the neighborhood.

Thanks again to all for the info.

Nick
