I have been chronographing different powders in my .50 caliber T/C Renegade with 1:66 barrel and lead round balls. I tested Hodgdon Pyrodex RS, Hodgdon Triple Se7en FFG and Hodgdon Triple Se7en FFFG.
40g Hodgdon Triple Se7en FFFG: AV-1396 fps, ES/SD-84/31 fps
40g Hodgdon Triple Se7en FFG: AV-1322 fps, ES/SD-47/20 fps
40g Hodgdon Pyrodex RS: AV-1103 fps, ES/SD53/21 fps
60g Hodgdon Triple Se7en FFFG: AV-1690 fps, ES/SD-41/17 fps
60g Hodgdon Triple Se7en FFG: AV-1603 fps, ES/SD-99/38 fps
60g Hodgdon Pyrodex RS: AV-1281 fps, ES/SD-70/27 fps
I tested 80g of Hodgdon Pyrodex RS to see if it would come close to the velocities 60g of Hodgdon Triple Se7en FFG and FFG gave me.
80g Pyrodex RS: AV-1578 fps, ES/SD-88/33 fps
I was not expecting the Hodgdon Triple Se7en powders to be that much faster than the Pyrodex RS. Given the 100 yard groups I've fired with 60g of Triple Se7en FFFG, it makes sense when someone tells me they are loading 90g of Pyrodex RS in their .50 caliber rifles to get the best accuracy with round balls at 100 yards.--->>> https://www.muzzleloadingforum.com/t.../#post-1512422
