After learning a lesson about the need to lube bullets I took my Witworth back to the range with one goal; get it to shoot with no malfunctions.
I shot 20 shots of 60 grains of 3FFF under the 580 gr. hexagonal bullets Pedroselli sells. I ran a cleaning brush down the bore after each shot and lubed the bullets. I did not use any kind of a wad / spacer, etc between the powder and bullet. I have 1.5F and 2F powder I know "should" be better, but for now I just want everything to function and smell some black powder
Couple questions:
Do bullet weight matter as far as powder charges go much? Obviously with smokeless powder it does greatly. In other words if I find a load with a 480 gr. bullet do I need to adjust the powder charge if I step up to a 550 grain?
What kind of velocity can I expect to max out at? I assume my 580 gr. bullet should get to around 1350 fps? I did run 70 grains of 3FFF for the last shot and it went 1110 FPS
The above 60 grains of 3FFF and the 580 gr. projectile had almost no recoil and averaged 1000 fps.
