Jon,

If you peruse the prior posts on this site, you'll find several discussions in detail about fire lapping. Also, highly recommend ordering the "Beartooth Technical Manual" that covers fire lapping in detail as well as a number of other items of interest for cast bullet shooters.

An additional source is an article in "Guns" magazine, August, 2001 titled "Firelapping for Accuracy". Their results with a .223 Remington 700 was an improvement from 1.237" (five 5-shot groups at 100 yds.) to 0.758.

I can only vouch for fire lapping from a single experience, but that experience was excellent. It did remove the barrel into receiver constriction and the barrel has noticeably less tool marks. I'm leaving this morning to test the accuracy improvement.

Jon,

Apologize for not being more specific -- didn't mean to imply that the firelapping data would necessarily be in just the "General Discussion" category. One post you may find interesting is located in the "Handloading Procedures" category and is on the second page, entitled "Handlapping versus Firelapping".  

Also, go back to the Beartooth homepage and select option "Bullet Selection". Then select either "Lapping Bullets" option or "Lapping Supplies" option and you'll see the material Beartooth offers you for "making your own".

If you don't want to make your own, the "NECONOS.COM" web site offers you bullets already impregnated. You can also order a jacketted (not lead) kit from Cabela's that is part number 21-4206 "Final Finish Bore Polish System".

But as before, I'd still recommend a copy of the Beartooth Technical Guide -- and the NECO web site also gives some information.  And the article I referenced in the "Guns" magazine used the NECO bullets for their firelapping.
