Fire Lapping?

[kevinsmith5]

I have a new .223 H&R Ultra Varmint I am thinking of fire lapping.  It is currently reasonably accurate with factory (about 1" at 75, haven't shot much). It appears the bore gets dirty fast and after I run a dry patch through the barrel I can see little threads from the patch hung on the lands. My big question on fire lapping at this point is whether anyone here with more experience (which would be anyone with any) has any advice on the process or opinions on products. Right now I am looking at the Tubb's Final Finish Kit since it seems the most idiout proof and complete of anything I've found so far.

I firelapped a 6mm Remington. What they advertise is true. The loads that shot 1.5" are not about 0.5" and the barrel is much easier to clean (one wet patch and 3 dry patches, and it's done). I think that the bullets also fly a bit faster.
I used only half of the bullets in the kit and cleaned really well with copper solvent between shots.
However, a Handi Rifle could benefit from a washer under the barrell lug, to relieve pressure from the handguard.
And you can try different types of ammo.
It it shoots 1" at 75, you have a good Handi.

   I have done a couple and I would suggest that you are very careful with a .223.
  When I did my first .338 it took awhile to get the bore smoothed out. But it was well worth it. The first group I shot after I finished was a seven shot group with all holes overlapping! Very impressive. I did a .30 cal. that cleaned up a bit quicker and shoots a little better than it did before, but, is much easier to clean now. Then I did a .243 that I should have been more careful with!!!! The throat pushed back very fast in that one. With 100 gr. bullets I can't seat them far enough out to touch the lands if I try. The gun shoots about the same and cleans easier but, I think I put allot of extra wear into the barrel.
  It appeared to me that the smaller the bore diameter, the less course grit abrasive you need to use. IMHO.
