Did ya clean all the copper out ???
How are you cleaning the lead out ???
Can ya push a bullet thru the throats ????
Is the barrel constricted where it screws into the frame ???
Last but not least do ya have another powder to try ? as I have bullets when switched to BE they lead ( I feel BE is so sooty it dries the lube in the bore)
Here`s how I delead a barrel & cyl. After an unsuccesful load It works so well I put the Lewis kit away !
Choreboy copper (all copper) pot scrubber wrapped around a brush after soaking with Ed`s Red
Chronograph ???
You may want to post this in the bullet casting section also, as there are some that shoot lead exclusively & have waded thru alot to get where they are now , me included
