Hand-Lapping with Boolits?

Wanted to get a general consensus on a thought process I'm going through for potentially hand lapping a new New Vaquero I just picked up that has a SLIGHT frame crush on the bore.

I've done laps in the past by hand pouring/casting my laps onto a small bore brush, BUT, right now my furnace is in storage (haven't cast my own bullets in 10yrs) and I'm not motivated to drag it out just to do ONE revolver.

I do NOT believe in fire lapping, so that is not a suitable alternative.

THE PLAN:

Rather than pouring the laps, I'm thinking about slugging the bore with a couple of lead bullets, then drilling an undersized bolt hole through them, threading a bolt with a clamping nut through the bullet, then using that as my lap. It'd be shorter, of course, than my poured laps, and I'd have to use something with a lot of bearing surface, but such animals exist.

Any reason why it won't work just as well as a poured/cast lap?

I'd send the gun back to Ruger. If there is a big enough difference in barrel diameter, your going to ruin the lands with a lot of lapping.
Second, a lap may do more than just reduce the smaller section, it can do damage to the lands and grooves to either side.
Have Ruger look at it. The gun is defective.
