fire (pressure) lapping
« on: March 03, 2004, 03:46:21 AM »
Got a fire lapping kit coming (had $$ and nothing to spend it on :grin: ).

When I was slugging my Rugerette 32 barrels (didn't know if they were .311 or .313--turns out .311 works fine) the slug came out all rough.  I was truly amazed at how rough it was!

So decided to try fire lapping (at CAS ranges this is not necessary).  I don't know how to do this so it would be something new to learn.

The short version is you fire jacketed or very hard cast bullets through the gun.  They are impregnated with finer and finer grit.  Think it goes from 220, 400, 800? and 1200.  Fire 6, clean, slug to check roughness and then go  to next finer grit.  I have pure Pb (lead)  plus tin an antimony so I can cast my own so I can do this on the cheap ($67).  The amount of grit should do about 10-12 revolvers, give or take.  I've got 6 revolvers plus two lever actions so I should be set ('course I've said those words before and have been badly mistaken :eek: )

Will keep you posted on process.
