I pull the barrel out once or twice a year or if it gets really wet on a hunt. Use a punch smaller than the pins by just a tad. Make sure the end of the punch is flat, not rounded, or you’ll slip and mar the wood. Punch the pins just enough that you can grab them from the other side and pull them out, even if you have to use pliers. Pop the breech end out first being VERY careful working the rest out if it’s tight and your stock is slim. Clean up under the barrel, dry it, wax, and reinstall, carefully. Oil the pins lightly before you put them back in. Treat it like it’s a gold pocket watch and not a fence post and you’ll be fine.
