This is a example of a modified jag I make for each rifle I shoot. The front land is about .010 smaller than the other lands. The dia. of the second land about .005 larger & the other lands are regular size. All of them are sharp & tapered back. The patch & jag have a arrowhead effect when you push it in with a patch, it pushes past the fouling & when you pull back the patching gathers on the sharp edges & grabs the fouling on the way out. It works very well, has for many years & keeps from pushing crud into the breech.
I swab down & back one smooth stroke with a liquid swabbing solution I make, and a tee shirt patch, just down & back & then load.
You can easily convert your jag on a drill press with a small 3 corner file. Use a mic & mic the lands as you go so you don't cut the jag too small.
The most repeated problem I see with people swabbing the bores between shots is they use pillow ticking or they use too tight a patch/jag combo to sway & they actually push all the cruds into the breech.
Swabbing between shots is not to clean the rifle, it is to keep the bore Consistant from shot to shot. The more consistant EVERYTHING is from shot to shot, the more accurate the load will be. You change any ingredient, be it powder, volume, lube, amount of lube, swabbing lube or amount of swabbing lube, how many strokes you swab, wetness of swabbing lube, anything you change will change the group...... Also you need to learn to adjust the swabbing lube & technique with the humidity. If you use a fairly dry swabbing lube amount on a wet day, on a dry day you will need it wetter, as the humidity that was helping you on the wet day is gone & you must compensate.
Also you must learn to read the crud you are swabbing out & look at it each time & adjust the wetness. If it gets soupy, cut the liquid back. If it swabs hard or is very dry, add more wetness.
Also attached a photo of a modified breech scraper. This is a 2 minute mod. & makes cleaning off a breechface so much easier. Be Sure you file the correct way so the scraper cuts as you turn the ramrod Righty Tighty... :wink: 2-3 twists & this lil mod will cut the fouling off the breechface in a heartbeat.
If I am shooting a long session at the range, I have a separate rod there with a jag such as this & about every 10-12 shots I scrap the breech to insure no fouling is building up there & helps keep the load consistent for groups..
