Does runing a brush from bore to breech affect a guns accuracy?

You should avoid aluminum rods whenever possible because the soft metal will become embeded with grit that can then act like sandpaper in your bore.

Plastic coated rods (I don't think they make many anymore) will do the same.

Coated rods are OK because the coating is not soft.
Also best to spend the extra few dollars for a 1 piece rod. Why cheapskate the extra $5 or $10 when your running it down the barrel of and expensive gun.

When buying a cleaning jag make sure it has a "lip" that is as big or bigger than the rod this will keep the sharp edge of the rod from contacting the chamber/throat when cleaning from the breech. Not all brushes and jags are made this way.

The important thing is to choose the cleaning method/materials that will cause the least damage.

Rule #1: Always clean from the chamber end if possible.
Rule #2: Use a means to center the rod in the bore, such as a chamber guide.
Rule#3: Don't drag dirty patches back & forth; push the patch through and let it drop off.
Rule #4: If you must clean from the muzzle, use a brass muzzle guard.

Thanks Buzzdraw.

Those are good and concise rules.

There are a few kazillion Mosins out there that have been counterbored (or should be) as a result of cleaning from the muzzle end with steel cleaning rods. If you've got a Mosin that shoots poorly, a counterbore (or, less expensive, a recrown) may be your solution.
