Fire Lapping

After reading "Thread Choke is Killing Me", thought I'd post this. And as always, I'm no expert but this worked for me.

I purchased a kit from Beartooth Bullets. It came with lapping compound & a couple steel plates to roll the bullets between.

I cast some very soft 7 BHN bullets to use. These bullets were about .453 raw.

I loaded them over 2.5 grains of Promo.

And seated the bullet on top the powder charge in unsized cases.

At the range I would fire six & wipe the barrel using my standard jag & paper towels for a patch after soaking the barrel & cylinder with WD-40. All this is cheap stuff & worked great for cleaning between strings of fire. I fired 18 rounds total.

The sixgun was my Liberty Ruger. The 45 Colts cylinder throats measure .454.

The 18 rounds removed the choke & the little leading I was getting was eliminated. Notice while the choke as gone the tool marks in the barrel remain. There is also a spot in the barrel that's been there since 1977 when I purchase the gun.

What is the reason to seat the bullets so deeply? Never done any firelapping. Thanks for sharing.
