I have a 09 Argentine mauser custom, In 7x57Ackley improved. I am on the 3rd firing of my brass and have noticed there is a ring in the chamber where the shoulder is. Did not see until the last firing. Looks like the reamer could have chipped and cut the grove. It does not affect anything, just looks bad and may have to push the shoulder back now.

This gun is important to me and kinda special, this rifle was the last gun John van Patten build before he died. John was a Pennsylvania. Gunsmith he was a student of p.o Ackley at the collage. Then later on was this shop Forman. John also had many machines that were from when he worked for ackley. John at one time was one of the only guys in the USA reboring barrel. If you look in the back of some old gun books you see him referenced there.

The reamer used for this gun was a reamer Ackley made him self. John built this for my 12th birth day, my dad was friends with him. About a month after picking the rifle up John passed away.

So my question is should I just have the barrel set back one thread. I'd prefer this the barrel has John's name on it. Or just get it rebarreled.

I believe the reamer was a tight neck this one is about .312 so I have to outside then the brass. I no longer have the tool. This does not leave much brass. And most factory 7x57 won't chamber.

Like to ask what would you do. By the way the rifle is a 1/4 moa rifle. 24 inche Douglas air gauge think it's a #2.
Thanks troy. DSCN0135.jpg IMG_20180703_184817.jpg IMG_20180719_222622.jpg DSCN0075.jpg sorry for the bad photos. I will see if I can take better one's. Also you can see the difference from the luepold and Talley base/rings.

I try to never fix anything that is not broken. If a rifle shoots that well, but mars the brass, so what. Is the brass in danger of separating? Is it showing any pressure signs ? You must know how seldom one finds a rifle that is capable of this sort of accuracy. I would write it off to the rifles unique signature. I doubt many will agree with me, but this is why we have an open forum. :thumbsup:

Ya it shoots good, the only problem I have is neck thickness. They will chamber but after firing the necks are right in the chamber making extraction very hard. Turning the necks to about .310 will solve that problem. It I don't have the Turner anymore. It does not seem to hurt the brass just makes them ugly.

I do need to get a AI full length die. I just use my normal 7x57 neck die. A fellow on the high road forum said I could buy his old set but money I tight right now.
