I've been having fits with my GM ball barrel. Poor accuracy and inconsistency mainly. The other day I closed the frizzen poured powder and rammed a ball and to my surprise I didnt need to prime! Opening the frizzen revealed a pan FULL if Swiss 3f! I wonder how much powder I've been blowing out of the vent all this time? 5gr here 10 there...I'm using T/C liners and the hole is rather large even though its stainless and has 250 rounds through it.Ignition is centerfire quick. No click boom , just BOOM. Got to work on it I guess.Ah , the beauty of tradition !!! If it was easy would it be worth it?
