Hello,
I've conducted chrono testing of my 8", pietta 1858 Remington and plan to do further research comparing it to my new 5,5" I picked up recently. I will post new results as they go, though it may take me some time to organise another chrono trip.
34 gr FFFg Schuetzen Black Powder
220gr .456 Kaido pure lead flat-nosed Bullet
1# 860 fps
2# 884 fps
3# 839 fps
4# 878 fps
5# 893 fps
6# 882 fps
avg velocity: 872 fps
avg energy: 372 ft-lbf
Similar to: .44 spl, standard pressure .45 ACP, 9mm
Notice: 34 grs of real black powder is as much as it will go into pietta 1858 chamber with flat-nosed 220gr Kaido bullet. Flat nosed bullets give best weight to volume ratio thus maximizing performance. I think stronger powders like Swiss or Old Eynsford could allow energies in excess of 450 ft.lbf similar to .357 through a 3" barrel.
I recorded the very last shot from my test and you can watch it here:
Recoil was significant for a black powder revolver but still pleasurable and controllable.
I did also a projectile comparison with a roundball and same powder charge:
34 gr FFFg Schuetzen Black Powder
143 grain .454 lead roundball
1# 964fps
2# 984fps
3# 980 fps
4# 967 fps
avg velocity: 973 fps
avg energy: 301 ft-lbf
Similar to: .38 spl +P
Recoil was significantly less.
Here's my test gun, 8" pietta 1858:
New gun to test, 5'5" sheriff another pietta 1858 to keep things consistent:
I hope you guys find these resources helpful.
Cheers,
Mike.
