I decided to chronograph some loads the other day just for my own information.
All I have currently is Pyrodex P so I set my measure for 17grains loaded 5 chambers with it and a .454 ball some cous-cous for filler (can't get cream of wheat over here!) and a wonderwad lit by a Rem No.10 cap. The average speed for that load was 596 fps for a slightly measly 110 foot lbs energy . The difference between fastest and slowest was only 24 fps which I thought was amazingly consistent!
The next load was double that i.e. 34 grains didn't use filler as wasn't needed now. The average for that load was 945fps for 278 foot lbs energy. ES was also low at about 35 fps.
The last load was triple that i.e. 51 grains minus the wad but a little grease instead. The average for that load was 1171fps for 426 foot lbs energy. Felt like a proper load with nice resounding BOOM!
Anyway just thought I'd stick it up here for information purposes.
Always heard that you can fill the cylinder to the top on these with BP or Pyrodex and be safe but is it skating on the edge or absolutely safe,????
P.S. The first two loads are always very accurate putting 5 into less than a couple of inches of a rest at 25 yards. Generally I just stick with the 34grain load. I haven't got round to benching the 51 grain load but offhand it seems ok but certainly not nearly as tight as the others.
The 1858 is a Uberti Stainless Target model with 8" barrel.
