Oh now blame me! I can't help it if it improved my avg groups by 1/4" average, and made the barrel easier to clean! If you haven't reloaded these type of bullets before, a couple of tips:
Follow The Manufactures Instructions!
(1) I used a .243 expander on .223 cases, use something larger than .308 for the mini 30 rds, maby a tapered rod, punch or drill bit, and a hammer tap? The idea is to bell the case mouth as the abrasive is mostly in the neck area of the bullet, ya don't want ta scrape it all off when you seat your bullet. (2) Use a very fast powder, but only a few grains. I used 3 grains of H110, in my .223, but you can use 1 or 2 grns. of Bullseye etc. Adjust the grains of powder accordingly for the 7.62 mini. The idea is to fire a very slow bullet thru the barrel, but MAKE SHURE YOU USE ENOUGH SO THE BULLET WON'T BECOME LODGED. VERIFY EACH RD CLEARS BARREL BEFORE FIRING ANOTHER OR IT WILL GO BOOM!!!!!!!
(3) Seat the FINE grit bullets FIRST, working up to COURSE grit LAST. You don't want the course grit residue in your final fine grit Bullets!!!
Before you Shoot the bullets:
Follow The Manufactures Instructions!
You MUST CLEAN your bore thourghly with a good copper cleaner. ( YOU MUST HAVE A CLEAN BORE, NO COPPER!). You can feel the tight spots in your barrel by pulling a soft .22 LR bullet, and using it is a feeler, by pushing it down your barrel with a cleaning rod, and a flat jag, push rounded end of bullet thru muzzle first with jag against the flat. You can feel the tight spots. Shoot the course bullets first to (almost ) eliminate the tight spots, then move up to the medium grit bullets, and final polish with the 600 grit, or your finest grit bullets.

CLEANING: Clean and degrease (the grit is held together by greese), shoot for record with your ammo, Clean barrel ,Lite oil, slug bore. Repeat each stage of grit.
Your milage will vary, I shot 10- 220 grit bullets, 10-320 grit bullets, Then polished the bore with the 15 rds of the 600 grit. I only used 1/2 of the bullets. Ya don't want to over do it. My first 5 rd. group was .92" again the above are tips only,and not ment to replace the kit manufactures instructions. That's what I did, and those were the results.

If done properly, firelaping will not wear out your barrel, NO IT WON'T! The idea is to remove any tight spots, and polish the rough machine marks from the bore, resulting in less friction i.e a smother ride for the bullet to launch, better accuracy, less frictional heat, less fouling, easier cleaning. It works for me
