I've never shot them in anything so I have zero knowledge about them . Do they require any type of lube using real black powder ? Do they leave plastic fouling in the bore ? How many shots usually before the get hard loading or is that a non issue since their plastic ?
I was mentally toying with the idea of trying some with my Lee 200 gr fn 45 bullets just to see what happens in my shallow groove 56 twist flintlock , yeah I know it's a RB barrel but last year I shot some with a heavy double patch and they were stable at 50 yds accuracy was only so so thought maybe a sabot with that same short bullet may do better , not trying to replace a RB just want to try it out to see what happens accuracy wise .
