For many years I shot REAL conicals out of my .54 caliber Renegades, and we practiced all year. I think I only bore brushed them twice a year. The lube on the conical helps to protect the lead from melting and also helps in the rotation of the conical in the trip up the bore.

When you clean your rifle between shootings, you will see small dull gray flecks of metal on your patch. That is lead. That means you might want to bore brush the barrel with some solvent. Other then that I just give them a hot water bath like normal, then a solvent patch or two, then an alcoholpatch to help dry them, some dry patches and finally an oil patch to protect them. I have four Renegades and they are all good shooters BUT one of them, I have never found a conical that will shoot well out of it. But it does shoot roundball excellent. So that's good enough for me.
