Now this is more like it.
The reference to dram equivalent says it all.

On another forum I got howled down & made to appear as a dangerous idiot for claiming 1250 fps with 7/8 oz of shot is easily achievable from 12g black powder cartridges, or even a muzzle loader.

Their opinion was that after 1000 fps the pressure was too high & you start to push chit uphill with a pointy stick.

Just listen for when the report starts to go from whoomph to crack.
O.M
