30-6 Posted March 6, 2012 Report Share Posted March 6, 2012 I have never used a bore guide as i have never needed to clean a powder burning rifle. Now i want to start a cleaning programme. I have two rifles ( CZ styles in .22 lr and .17hmr ), so both are identical apart from calibre. I know i need different size rods and paraphanalia, but do i need different size bore guides ? Does a bore guide only go up to the breech face or does it enter the chamber, and so make it calibre specific ? Quote Link to comment Share on other sites More sharing options...
henry d Posted March 6, 2012 Report Share Posted March 6, 2012 Personal preference but I don`t clean the .22lr and I don`t have a 17. Quote Link to comment Share on other sites More sharing options...
coyotemaster Posted March 7, 2012 Report Share Posted March 7, 2012 I use the same guide for my .17s and .22s (different rods obviously)--most bore guides are tapered and fit into the rear of the chamber ideally sealing out the leakage of cleaning fluid. Mine are made by Stoney Point but there are others that are better. Some come equipped with o-rings to seal, but I think they are pretty caliber specific. I do applaud your using a guide it eliminates some wear on the sensitive throat area of your barrel. Quote Link to comment Share on other sites More sharing options...
Blunderbuss Posted March 7, 2012 Report Share Posted March 7, 2012 (edited) I very rarely clean the barrel in my .22 and accuracy goes right off and takes a lot of rounds to recover if I do. I could probably get away with never doing it, but I feel neglectful if i don't every now and then, but immediately regret it when I sucumb to the cleaning urge. The .17 does respond well to a clean though, a couple of pull throughs with a bore snake every 50 rounds or so and a proper rodding through about every couple of hundred rounds. For me, the .17 is the opposite of the .22 in that accuracy noticably tails off if you don't clean it, and immediately (or after one or two fouling shots) improves when you do. Probably because the bullet is copper jacketed like a centrefire bullet and is doing more than twice the MV of the .22 so copper fouling builds up. I use a proper copper solvent when I clean mine, and I have to run a lot of patches through before they come out clean. If you are a cheapskate like me, an acceptable bore guide for a CZ rimfire is a 20 bore empty with the primer punched out.
