I just got my small action mauser put together with a short chambered barrel. I am about to rent a reamer and would like to hear some advice from someone who has done this before. I think my son will like his christmas present.
OK, first, use lots and lots of oil, second go very slow, cut a couple of turns in, then clean and use the GO gage until the bolt will just close on it. Remember to remove the extractor from the bolt for these tests.
Just remember you can always take it out, but it is very hard to put metal back in!
Be very cleanly.. If any metal shavings remain in the chamber a head space check will be bogus and inserting a reamer with metal shavings can lead to a damaged chamber.. When the reamer is removed, clean and clean the chamber too. Also as I'm sure you've heard... NEVER EVER turn a reamer backward!!!!EVER!. Also I prefer to do this with the barreled action vertical. No side pressure is exerted on the reamer...
What caliber is the youngster getting this Xmas?? I built my lovely daughter a 280 on her 16th Xmas. She's 25 now and had to shoot a deer the second time this year.. Actually the doe was down but paralyzed and she simply put it out of it's pain.. Her boyfriend killed a real monster..likely over 200 inches gross and very old. He had a lot of character points (dagger,spurs, etc) but will be scored most likely as a main frame 10 point.,.
