Bigsmoke, This is the factory .54 barrel and I checked the touch hole today with a 3/32 transfer punch. Pretty ugly. The whole barrel needs to go back about 1/8" but thats not doable, so being as though the new barrel has the same length breech plug, I'll either have to drill the touch hole at the same angle, OR maybe it would be better to install a coned th intersecting the face of the bp or very slightly rearward of the face.
