I was afraid to sand near my lettering as well. The JM stamping was very shallow to begin with so I hardly sanded that ares. Usually I submerge my barrel in vinegar for a few days but I couldn't get me recovered pin out so I refinished the barrel attached to it. I sanded very little and lightly with 400 grit. Brownell's told me to try wetting 0000 steel wool with Oxpho blue and rub it in wet to try and get a darker finish. I don't think it got it any darker but was worth a try. If anything I think it made it lighter and removed some bluing so I applied a few more coats the normal way after wards. I will tape off the barrel before I start sanding and painting the receiver. If it's not a shooter luckily I have a few other 22's I'm my arsenal that are tac drivers. Just funnier to shoot the stuff to me. I haven't owned a 22 rifle in decades...just pistols. I have a bunch I've acquired in the last couple years. A cz452 ultralux super exclusive, Anchutz Woodchucker, Remington speedmaster, Winchester 1902 boys rifle(I just sold), a 6mm flobert, a ruger American 22 wmr (my favorite)? and the two above. Forgot I bought one of the H&K mp5 clones but never shot and sold it off a few years back. I just like the hunting rifle configurations. Seems like the 22 wmr normally gets picked in the first line draft every time.
