You don't say what kind of conicals you are using. if you are using modern pistol bullets with a plastic sabot, they seldom shoot well in a rifle with a rate of twist of 1:48. That twist rate is too slow to stabilize them well. For a conical, you need something like the T/C Maxiball or T/C Maxihunter. It will usually shoot the Lee R.E.A.L. bullet pretty well but the modern plastic stuff is best shot in one of those infernal inline devices with the plastic stock and high powered scope. YUK!!!!!
You don't really need any lube on fiber wads, they are bestg used dry. Let me suggest using leather OP wads lubed with something like Ballistol. I buy scraps of 5 to 6 oz. leather for pennys. I bought a set of hollow punches from Harbor Freight for next to nothing. I use a half inch punch to make my leather wads. I place them into a jar and pour Ballistol on them and let them sit for a couple days to soak up as much Ballistol as they will. I then remove them from the jar and use rags to pat them as dry as I can. I load one of these wads on top of my powder and then load my PBR on top. it sure improved my shot to shoot consistancy and consequently my accuracy. My patch lube is also straight Ballistol. I put the pre-cut patches in a jar and dampen them with straight Ballistol. I take a stack of the patches and squeeze oout as much Ballistol as I can. They should just be damp ,not dripping wet. With the leather OP waqds and Ballistol patches, I can shoot all day without having to wipe the bore. It is amazing. :thumbsup:
