in my '98 Mauser has a sort of rough chamber. instead of taking to my gunsmith to put on a lathe, i'm going to take a drill and a slotted dowel and i'll put a piece of Scotch Bright on it. if that don't work, then i'll try 320 grit. then if all else fails, to the gunsmith i go.
there is a small vertical elongation, or like hair like, in the chamber. oh, i took '06 brass and i reformed it to 8x57. i fired the 8x57 and it got stuck in the barrel. i had to take a rubber mallet to the bolt action to turn it. then a cleaning rod to take the bolt and brass out. i looked at the brass and i found the scratch mark. using my calipers, i found out that i should turned the outside of the neck. it was .003 to .004" above the neck dia. so i got the Forster neck turner out and turned the cases.
i shot the 8x57 again and they cycled perfectly, but i seen the case was scratched, again. the first thing i did was to clean it again and this was time i noticed a "hair like" elongation. i took the bolt out and i put on a brass brush (444 Marlin brush) on the pistol cleaning rod and i spent about 3 hours using Kroil on the brass brush and the chamber. i got most of it off, but i can still see it and it still does scratched the brass (3rd shot). so i decided on the electric drill, slotted dowel, scotch brite and 320 grit.
someday i get this 8x57 shooting again.
