Finally took it out to the range yesterday, shoots great with a couple minor issues. Cleaning rod won't screw in properly so it walks out while shooting, and the bolt is tough to close on a loaded chamber. Anyone have ideas how to improve the bolt issue?
Get some compressed air into the slot that holds the cleaning rod. The nut inside probably has dirt in it or is a little rusty. Putting some oil on the threads of the rod and applying pressure while screwing it also helps.
Bolt issue can be a lot of things, here are the remedies that I'm aware of:
1) Clean the bolt in hot soapy water while disassembled to get any gunk out.
2) Clean the chamber really well, get a 20ga bore brush in there with some solvent and toothpaste to polish (mild abrasive, just plain white toothpaste).
3) Make sure the magazine isn't sitting too high up, if the stock is compressed or improperly inletted this can happen, shim the tang and recoil lug and shim under the magazine.
4) Very, very slightly polish the extractor where it slides over the rim.
5) Very, very slightly polish the extractor edge where it clamps onto the rim.
6) Check under the bolt at the rear for scuff marks, this may be an indication that the bolt is riding over and being interfered with by the interrupter / ejector assembly.
7) The inside edges of the bolt face, where the outside of the case rim would sit, a very, very slight polishing here,
do not polish the bolt face itself.
8) Polish the bolt where the cocking piece and bolt body meet and turn.
P.S.
For the love of God please do not sand the stock, if you want to refinish it then restore it, strip with denatured alcohol and apply shellac.
