jag sizes

Help! I need someone with a micrometer to tell me the jag sizes of a 12 ga., 10 ga., a brown bess and a .69 cal Charleville musket. Thanks in advance, Dread

I would think the jag size would be the same as, or close to the roundball's diameter of the gun...

After all, you will have patching material on both sides of the jag, just like a roundball is patched...

My .75 has a .720 jag, so .015 cleaning patch on both sides of the radius brings it up to .750 diameter...

.015 + .720 + .015 = .750

Well Dread, i normally go to the store and buy one that says .12 ga, .10 ga., .69 cal. etc. Works for me. :: :: And why doesn't a great gun builder like yourself have a mic in the first place? HUH HUH :hmm:

I don't presently have any jags that large but after miking .45, .50, and .54 they seem to run .025-.030" under the stated bore size, hope that helps. ::

Just a wee hint. Try the next size smaller jag, especially for wiping. The patching/cleaning material will try to rollup at the top edge of the jag and will do a better job of getting soft fouling to ride up and notdrop back down past the patched jag. This won't work if the next size smaller jag is a lot smaller in diameter...like a .69 in a .75, etc.

I'd say you is right. I make my jags about .030 under bore size. Sometimes a feller will want one a little smaller cause they're using extra thick patches. The ones for chambered barrels are a real pill to turn. Those .75 jags are big enough to use as a weapon themselves. :crackup:
