What Iāve noticed is after waxing the first shot is always back on POA / POI and you donāt have to send 20 or so down the pipe to season it and get your accuracy back. Itās pretty amazing.
True, this is a topic we were discussing here not too long ago.
Here are a couple of examples. First is a .22 cal QB79 HPA conversion fitted with a choked LW barrel. This barrel isn't too bad after a cleaning. It normally needs about 10 pellets through it for the POI to stabilize. With wax applied, it groups straight away. This is the first 5 pellets at 30 yards:
If it weren't for that cantankerous little guy to the left, it would have been right around MoA. No hard feelings, they're Daisy pellets after all.
Up next is a .177, also a choked LW. This is a barrel I thought I had damaged somehow the first time I cleaned it. Pellets were going all over the place and then it finally started settling down after 30 pellets were through it. I've repeated it twice more so I know it's not a fluke.
Here it is today after a clean and wax. It falls in line with less than 5 pellets:
Yes, it made a sub-MoA group with wadcutters at 30 yards. No, I can't do that every time
If you want to try it, get the bore good and clean and then follow up with a suitable degreasing solvent. For the cleaning step, use whatever you like--Hoppes 9, Ballistol, WD-40, Kroil, Goo Gone, etc. They're all capable of getting a barrel clean in fairly short order unless it has been neglected. Then degrease with either acetone, alcohol, or mineral spirits. Use acetone for its excellent degreasing properties and fast evaporation but don't let it get on any O-rings. I'd say alcohol is second best but once again don't get it on your O-rings. Or if there's an O-ring involved that you can't (or don't want to) remove, use mineral spirits. I've used all 3 in different situations.
For the wax, I've used fancypants One Grand Blitz Wax (caranuba) and good old Johnson's Paste Wax at different times and the results appear to be the same. I use a pullthrough cotton patch 5 - 10 times to apply the wax, putting a little more on for each pull to ensure there's enough to coat the full length of the barrel. This topic was being discussed on another forum a while back and Scott (motorhead) recommends a mop and a back-and-forth scrubbing action so you may want to follow his advice instead. That's my preference too when I can work it from the breech end (e.g. a breakbarrel or a PCP barrel before installation) but my policy is don't put a cleaning rod into the muzzle if it can be helped so patches it is most of the time.
When done, just leave it to dry fully and then get to shooting. No need to run a patch through to buff it out. The first pellet clears it from everywhere except the microscopic pores.
Another helpful point Scott made was that it isn't necessary to start over when the next cleaning is due, just run a couple of snug-fitting dry patches through and accuracy will return. I can attest to it as well. I think he said he cleans just once at the beginning of field target season and occasional dry patches are all that's needed to make it through the season. I'm sure he's done the J-B treatment to the bore so I wouldn't count on that kind of longevity as a general rule but it should give some indication as to the benefit of this step.
