serious question [ruger 10-22]?

Question

I've put a Adams / Bennett barrel on my 10-22 and it shaves a little lead when it loads and if it isn't super clean it'll jam . I've been using cheap ammo I use the same ammo in a autoloading pistol with out a problem. I was thinking if I put a slight radius at the breach where it loads if that would help. other than that it shoots 1/2 groups at 50 yards 1 1/2 at 100 yards. I know there are some serious shooters out there. Help me out if you can.

Answer 1

What you are dealing with is just a very crisp sharp edge, and the really cheap ammo is usually softer lead then the copper coated ammo or the more expensive ammo.
Just de-burr it so it has no sharp edge that all.
Take a pence and super glue one of your fires 22 cases base (rim)to the pence and apply some fine lapping compound to the “rim area only” and insert it in to the chamber and using just the palms of your hand spin it back and forth slowly several times you don’t wont any of the lapping compound to get in the chamber area what so ever.
Then clean the barrel and chamber before using, you only won to dull it not reshape it.
You don’t wont a true radius to speak of just dull down the sharp exposed corner.

If you don’t feel safe doing this have a gunsmith de-burr it for you.

Hope this was of some help.

Answer 2

Lapping compound (as per D-58) or maybe the new molybdenum disulfide, possibly just touch it with wet or dry 400grit and 0000 grade steel wool. It will only take the smallest amount of abrasion. I use moly disulfide sometimes on a patch (have mine suspended in a modern oil) and run it back and forth about 20 times. The cleanup requires bore solvent and you'd need to clean it more than once, at least twice to get the black stuff out.

Answer 3

The price of the ammo is really not all that important in 22 rim fires. First try other brands of ammo. If no others will feed properly, shoot accurately, and eject consistently then try to modify the barrel.

Answer 4

Something loose in breach like your trying to push rope in to a garden hose are guid shims stillin it tighten up breach assmbly so it loads rounds straight from mag to chamber

Hold the little cocking lever move up and down side to side you will probly see excess movement or have gunsmith ck it out

Assuming new barrel spects match orig and it tight to reciver
