I have the .001 oversize hinge pin, the stronger hammer spring and the lockup springs from Bellm. On the guns with wooden stocks and forearms make sure the ears of the forearm are not touching the front of the receiver. It the forearm ears are contacting the receiver accuracy can go to pot.
My Encore is not picky about loads at all. It shoots the 200 grain SST, the 250 grain SST, the 240 grain .430 XTP and the 350 grain FPB really well. By varying the powder charge i can make that gun shoot the 200 grain SST, the 250 grain SST and the 350 grain FPB to the same point of aim out to 75 yards. After that the FPB starts to drop. The 200 grain SST and the 250 grain SST will go to the same point of aim to well past 100 yards.
