Is there alot of leading in the barrels when shooting conicals?
And what do you guys use to clean it out with?
And one last question do you guys use jb paste as well in sidelock barrels to help the breakin period

no theres not a lot of leading. Depending on the powder i shoot, i use birchwood casey 2 in 1 bore scrubber to clean the lead/copper fouling out. If i use pyrodex, t7 or american pioneer i clean with water and dry, follow up with the bore scrubber and let it do its job.

I normally do jb bore my barrels now and depending on what they look like when they arrive i can do as many as 200 strokes to smooth one out. The great plains rifle i built for someone got 200 strokes to take out the sharp rifling those italian rifles come with.

I shoot a White Rifle and put hundreds of conicals through the gun, and you'd hardly notice any lead build up. All you need is a good solvent that removes lead and a brush and scrub the bore if you suspect leading.

When leading happens it's important that it be removed ASAP. Rust can take hold under the lead.

One more advantage to shooting a PRB. No leading at all.

A good lube on the conicals your shooting helps prevent any leading problems.i shoot conicals all the time in my Wolverine and clean it with Birchwood casey bore scrubber. it always looks like new when i am done cleaning.the lubes used by No Excuse and bullshop are top notch lubes.

There are two ways of looking at your JB question. Basically if you use JB you are doing a process called "lapping" the barrel. Barrel material and quality of barrel machining is one of the differences between less expensive rifles and higher end rifles. And some mfrs. hand lap their barrels before they ship them, and some don't. Now in the MZ business most do not hand lap the barrel.

There are two schools of thought. The first is that all barrels should be hand lapped before being shot. And the second is that a barrel should not be lapped unless it needs to be(rough barrel, patch tearing, or bad leading problems with properly sized bullets).

Personally I lap most barrels unless it is a high quality barrel. Again this is not the type of barrel you are liable to run into in an MZ.

Lapping a barrel will smooth it out and will usually leave less leading in the barrel. Again as long as you have properly sized bullets. Bad sizing of your bullet will cause more leading than anything else. I even like to use tooth paste after I use JB for a real final polish. Since toth paste is also an abrasive, but not as abrasive as JB.

For lead removal that is simple. Just buy any good commercial lead remover. Tom.
