Talk of best type of cartridge for breaking/running in the 1919, what combination do people think is best.
MV/FPS Speed ( range from to ?) Powder grms ? Shot/lead size ?
Is it better to have a high MV/FPS and large Shot size than a high grms ? for example...
(i.e. 1450 fps, No.7.5 Shot, 27grms....or 1350 pfs No.4 Shot, 32grms ).
I read somewhere ?, its better to have a heavy lead load to compress the gases to work the gas system.
What is considered a "heavy lead" load ?
