Hello all,
I have a 0.45 Philadelphia derringer, with a 2.5" barrel. I"m looking for the most potent load. With longer barrels, the heavier the load, the faster the bullet. Simple.
However, in this short barrel, the powder thakes a significant part of the barrel length. So heavier load means shorter barrel.
Can you provide info or ideas on getting the best load?
Also - what about using 4Fg instead the regular 3Fg? Would it be safe?
I dont have access to chronograph, so cant simply experiment.
One more: how do I measure barrel length? is it the Inside bore length? The total outside length? other?
Thanks,
