I received my Pedersoli Sharps Berdan back from Charlie Hahn after having him do his complete job modification, the solid breech block and o-ring fix. Charlies work is outstanding. 40 rounds through the rifle and no freeze up of the breech block. Another plus was the forearm wasn't full of blackpowder fowling. With the original Pedersoli type breech block, the fowling blew up and under the forearm making it black inside. With the Hahn mod, I couldn't find any bp fowling in the forearm. Thanks again Charlie!
I did some chronographing with a few loads. The bullet is a Rapine ringtail, cast 1 part lead and 1 part wheelweight, weighing 471 grains, lubed with Len's Lube, Charlie' tube 1.5" and RWS caps, 3 shot average, @ 15 feet, Pact Chronograph, 52 degrees.
50 gr. Goex 2fg.= 870 fps. Extreme spread=36fps
60 gr. Goex 2fg.= 955fps. Exteme spread= 11fps
3 shot groups @ 50 yards are 1 inch and sometimes just one hole. At 100 yards the rifle will put 3 shots into 2 inches off a bench. This is with 50 grains of 2fg.
The trajectory is + 5 high at 50 yards to hit dead on at 100 yards.
I made a shim that I can place under the rear sight where it pivots to put the rifle dead on at 100 yards. When I remove the shim, the rifle is zeroed +2 inches high at 50 yards. Works well, and no permanent modification to the sights. That way I can use the rifle deer hunting as well as skirmishing in 2014 when I join up.
