Just wondering what you guys think about this subject. I was contemplating this for my SBHH but don't know much about it.

Thanks,
Erick

Personally, I've not seen the need for it. This does not however, mean I am opposed to fire lapping a barrel. If you choose to do so, I would go with John Linebaugh's suggestion and swab some of the compund inside the forcing cone of the revolver and not coat the bullet. He has told me that coating the bullet does a wonderful job of spreading abrasive compund all inside the workings of the revolver.

I would recommend that if you have not shot your SBHH much; to go put at least a couple hundred rounds through it and see how it settles in before you firelap the barrel.

When you prepair a bullet for lapping you should roll the bullet between two pieces of steel to charge the bullet as you would a lap. You don't want a bunch of excess diamond compound in your gun. I would only do this with a bore that you feel is excessivly rough and causing leading problems. If you have a good bore you wont accomplish much. If your bore is rough it can work wonders. I did this to a SS Super Redhawk and cut my groups in half. You can buy pre-charged bullets for fire laping but I don't remember who sells them. Probably Brownells or Midway. This would be the easiest way to go if you don't know much about laping and laping compounds. You need a very fine diamond laping compound to do this. Too course of abrasive and you'll ruin yor bore. Also your load should only push the bullet to a couple hundred FPS, just enough to make sure it leaves the barrel. You don't want to push it any faster than you have to. Hope this helps. KN

I have the old lapping kit that veral use to sell and i think he does again. I have had good luck with lapping bores. If you want an easy way Beartooth bullets sells ready to go lapping bullets.

I'm sure Veral at LBT sells the compound. I've used it and had good results. I also recommend his book. The man has forgotten more about cast bullets than I'll ever know.

That said, by all means shoot the gun a few hundred rounds before deciding whether or not you need to do this. It is a bit messy.
