Well I didn't order a THM, but I do have a Volquartsen stainless match barrel on the way. I cleaned the factory stainless barrel with my Outers metal cleaning rod and some patches soaked in CLP, then some dry patches.
I don't have a brush for a .22LR yet, so that's why I asked. I use the bronze on my USP's (and my old Glock), and I don't see why there would be a problem there. I suppose I could use nylon though, since I only shoot factory jacketed ammo.
I need to buy some quality rods and brushes, and some sort of compartmentalized box to keep all my cleaning junk, manuals, and bottles of lube/MPro7 in. Tackle boxes are normally too small to hold the MPro7 bottles, but my little CLP dropper would fit fine.
I know about Rimfire Central, but the site loads so painfully slow for me that I don't bother on a regular basis. That's odd, too, because I am on a dual T3 school connection.
