32rf To 22rf

How difficult is it to convert Winchester 1885 LoWall with trash bore in 32rf to 22lr? Looking for cost effective ideas. Thanks.

Drill out the shot-out barrel with a piloted drill, glue or solder in a .22LR liner, cut extractor slot, extend extractor and chamber.  You may want to cut away the bottom of the breech end of the barrel and fit a .22 extractor.  MVA, C. Sharps and other outfits should have a blank extractor for sale.

You may need to make a new link with slightly longer spacing so the .32RF firing pin rises enough to hit the rim of the .22LR, but you may get lucky and it might work fine as-is.

Doesn't sound too difficult. Should be a doable project even for someone with two left thumbs like me. Thanks.

The drilling operation is best done on a lathe.  And commercial liner drills have a pilot that's too small to guide in a .32 RF bore.  Still worth a try.

My biggest concern was aligning firing pin with smaller rim. If a different link will solve that problem everything else sounds peachy

Going from 32 to a 5/16" liner does not take much. A standard 5/16" drill bit will take the rifling out which is all you need to do. No need for a piloted drill as your only opening it up to groove diameter. I did a Frank Wesson a while back and it worked fine. Making a new link may not work as well as some think. It changes the hammer sear engagement. It's not to hard to drill a new hole in the breach, cut off the old firing pin and install a new pin in the old firing pin body. The hard part would be fitting a 22 rim fire extractor. The way they are set up the cut in the barrel hold the extractor up so the brass does not bulge on the bottom.

Yes. The centerline of the pin tip only has to move about .050 closer to the centerline of the chamber.  The diameter of the firing pin body in a Winchester is plenty to accommodate that.

Buy a good quality liner.  I once bought half a dozen cheap from Numrich.  Cheap because they were oversize on the O.D., which caused me no end of trouble.   I knew better, and did it anyway.  Embarrassed
