Figure choke from pellet count ?

[OH Osthaus]

Thanks Chuck

now that I have the load on a letter, i will be interesting to see if I can duplicate the results. black powder fiber wads an all

great chart
interesting that the powder charge changes with the barrel length and weight of the gun - for 10 gauges 9 1/2 lb is the break point and its lists 30 and 32 inch appropriate loads.

i can understand the charge and recoil, not sure if 2 inches of tube after 30" will make much velocity difference. but great data
