Keep an eye peeled for fingernail polish sales. Since acetone is usually the release agent for these, they weather things like Mineral Spirits & Hoppes with ease.It would be really nice if jags and other rod ends came with a caliber label inscribed on them. ...
I bought a $3 Plano lure box that has 6 sections and used a marker to label each for the caliber. Simple and cheap, I can keep brushes, jags, etc. all in one section.It would be really nice if jags and other rod ends came with a caliber label inscribed on them. There's no way to tell what caliber a piece is for unless you keep it in the box it comes in. Do any companies make brass jags marked by caliber?
Some bronze bore brushes will be oversize. If you start a fat one into the rifle bore, its nearly impossible to pull it back out. The brush has to be pushed to the end of the muzzle. This may bend a steel coated cleaning rod.
I now measure the diameter before i use it. A 243 brush should not be larger that a few thousandths. The nylon brush is more forgiving, but may be oversize also.
poor quality control
Necessity. Copper-bronze brushes erode from contact from copper solvent cleaners. Made oversize, there is more use out ofthem until they shrink down to less than bore diameter.I don't understand why brushes are made oversized
Sure there is; calipers. Diameter +(2x) patch thickness should be slightly more than actual groove diameter. Some of us old guys 'eyeball it', and the method I mostly use is to keep the jag on the rod used for that caliber, because you'll run the jag down the bore before the brush anyway, and reattach it to store when done.There's no way to tell what caliber a piece is for unless you keep it in the box it comes in.
