The load is whatever works for you. 3f will perform best. Anything over 30 grains is wasting powder. Your most accurate load will probably be in the 18 to 22 grain range. If the bore is good it should be a fantastic shooter. I picked one up a couple of years ago and haven't shot it yet but I have high expectations.
I agree. It's an in-line with very little if anything that is historical about it.
I suppose someone back in the day might have had a custom gun builder make a pistol that used the grips off of a Colt cap & ball revolver to make something like this gun but if they did, I've never heard of the pistol being discovered.
The Tingles were a well made series of pistols and traditional rifles made in the US. Initial Tingles were 40 caliber with a removable barrel to exchange a larger gauge smoothbore barrel. The pistol line was sold to Armi San Marco and they made the 44 caliber (0.433" or 0.437" ball) version. Very accurate. Mine was until the sights loosened and I haven't got the sights properly adjusted. Mine is stamped Palmetto.
The design of the Tingle includes a hammer stop so the hammer stops at the top of the cone and allows for dry fire practice. There is just enough clearance for the hammer to strike the cap but not hit the cone. My properly set up Tingle would only fire #11 magnum caps but would not fire #11s.
Apparently a popular enough design for Italian manufacturers to bootleg copies.
Mine is stamped "Hopkins & Allen" and I know that's BS
But she's a great shooter after I adjusted the design of the rear sight blade a bit
I believe it's referred to as a 'Prospector' because of the etched designs on the receiver
A bear descending a rock bluff over a guy panning for gold
And a wagon train on the opposite side
Very nifty indeed
