the key to sustained fire with a BP arm is keeping the fouling soft. The lube must mix with the fouling and keep the residue from forming a crust. Natural products seem to do this best but petro based will also work to some extent. Bees wax and pure tallow ( mutton, beef, bear) work best in that order. You can soften the lube with olive oil and other natural oils also.
The bullet you select must have a proper amount of grease grooves and or wiping groves to assist in the delivery of the lube and removal of the fouling. most of the bullets that are used in thee arms are rather short with multiple grooves to carry grease/lube. My favorite is a 509 Eley ( a very old Ideal mold) for small bored barrels and Lyman 515139 for the rest.
one other item to check would be the Nipple or cone. Just a small amount of wear can have a huge impact on accuracy. the top strap screw is also key to the overall function as well as the but screw that attaches to the frame.
attention to all of these should allow you to get back in the 10 ring.
