Ask 50 rimfire shooters and you'll most likely get 51 answers. I think using a boreguide, one piece rod and going slow might be common agreement. But every rifle is different. Using a borescope I have determined that like barrels need different amounts of cleaning. Cleaning will vary depending on brand of ammo used and how many rounds a barrel has through it. Usually they need more cleaning when new. No matter which of the above methods, rods solutions used, you need to shoot a clean barrel to see how many rounds are needed for it to settle down and reach it's peak accuracy and then keep shooting to determine how many rounds you can shoot before accuracy starts to deteriorate. To me a Dewey rod is just fine. Price is reasonable compared to other quality rods. I prefer the coated rod because I am not convinced trapping a hard particle between a uncoated rod and the barrel is a good thing. Polish the ferrule where the jag and the rod connect. I also use two rods when I use a brush so I don't have to switch between jag and brush. If you use a brush Shooters Choice Lead remover works well. If you don't want to use a brush you will find many of these solvents don't work well without a brush. Rich
PS. Also different solvents take more or less rounds to get a layer of lube in the barrel. I suspect some hinder lube from sticking in the barrel making it necessary to shoot more rounds before the barrel settles down. You want a cleaning method that takes the fewest rounds for your gun to settle down and shoot its best.
