I purchased a new/refurb Wingmaster recently and it's giving me some troubles with extracting that aluminum hulled crap Winchester makes. It has little trouble with the brass hulled shells, and has fired numerous 3" Magnum bird loads without a hiccup, but it stumbled in the 2-3/4" Winchester target loads. Anyone know someone in the Calgary area that could do a chamber polish for me? Normally I would tackle something like this myself, but a curious lack of jobs in the Machining industry has left me without access to any of the equipment I would want to use.

If it's worth it I will send out, but If i'm sending out I might as well get work like back-boring or chamber forcing cone extending done.
 
Does a 12ga mop fill the chamber? If so, slap some mag wheel polish on it and spin it slowly in a hand drill. If not, find something that does fit.
 
Sandpaper is for wood and wheel polish is wheel polish.

Make a dowel to fit in your hand drill and long enough to reach at least the first half of the chamber. saw a split in the end of the dowel for 3/4's of an inch. Buy some 180 grit wet/dry abrasive. Make 3/4 inch wide strips... insert in dowel and wrap around, over lapping until chamber diameter is achieved. Spin in and out of the chamber keeping the cross hatch working. Work at it for a few minutes mostly at the back... Clean and test.
 
12 gauge bore brush (the brass ones) thread it onto a peice of cleaning rod wrap the brush in some fine steel or brass wool throw some oil on it and spin it in a drill.
Boom done

That will clean a chamber very well... but polishing involves removing a slight amount of steel to smooth out the ridges in the chamber that are causing the cheap ammo to flow into and catch...
 
I use a 12ga cotton mop/swab, wrap a large cleaning patch over it and smear some Fitz polish on the patch. Attach to a drill and let 'er rip for a few mins.

SO, what you're saying is that this will clean a chamber very well... but polishing involves removing a slight amount of steel to smooth out the ridges in the chamber that are causing the cheap ammo to flow into and catch... ? lol

Basically yes. That has been my experience. When it comes to a rough chamber and soft brass I have found making it shinier doesn't work as well as making it smoother... smooth out the ridges by removing very little steel from the 'high' spots, making it more even and no place for soft brass to flow into and hang up.
 
I second with guntech with the polishing vs squeaky clean, have to remove the rough edges in order for it to be a proper polish. I do question the grit though, would it be better to start with 400 wet and spend a little more time with it? Or just play it by how rough it is to begin with?

I thought about doing the same thing after this past weekend. GF and I were out shooting skeet and we both had the same problem cycling target loads, I was using an 870 and she has a Mossberg; same problem with both guns. It was usually the second or third shell jamming. She was cursing like a sailor and that alone made it comical enough for me to not get frustrated when mine wouldn't cycle properly.
 
I used 400 oiled "emery cloth" (not sandpaper...) with oil, wrapped around my finger with even coverage similar to honing. Finished with some 800 after cleaning.

I'm sure someone will crap on that but it worked for me

I've done the same thing only I used fine lapping compound. Slightly more abrasive than just the steel wool but not enough to cause damage to the chamber. Lapping compounds come in different grits so you determine how aggressive you want to get.
 
So I found a possible solution, try Federal Ammo for target rounds, none of the same problems and the Winchester loads. I heard challenger work well and they're Canadian made.
