Bringing this interesting thread up again.

I many of you know I have a Rigby Shot & Ball gun which seems to have sqeezebore or chokebored barrels where the barrelwalls seems to have 3 "grooves". The barrel dia starts out with aprox. .743" and ends up in .735. I have tried with Blue dot powder and a .735" roundball. That combination could make anyone make a run after the balls as they came out of the barrels. Some actually landed down on my feet more or less..:LOL

I have a .750" roundball mold actually. Would it be safe to fire softlead balls of that caliber in such a gun taking I use FFg Blackpowder perhaps?. I have thought of ordering a .744" RB mold but just wondered if it were safe enough to fire soft .750" RB in my gun.




I think you are on the right track. I'd try Unique and/or Blue Dot though. The round balls weigh a bit less, but Unique loads for the slightly heavier Fosbery Slugs are well published. A good place to start. Some lube would be good, might have to add some tin to keep the leading down too? If you have a .750 mould and a .743 groove diameter, why not make (have made) a simple sizer or two?

What are you using for a gas seal? Sherman Bell uses a nitro card with thick cork. We can't even get the thick cork here, but I think you could order directly from http://www.siarm.com/index.php
