I talked further with my buddy who has the Pedersali that he opened up to 45-110. He told me that that the guy who did his smith work had done four others and all of them shot fine after rechambering. I guess that would speak well of there regulating methods wouldn't you say. The smith told him before doing the job that it was a crap shoot and if it didn't work than you were screwed because as stated earlier they are hot brazed. He gave me his load recipe's, but I forgot to bring them in today. He also said that the price of the new ones now are up to 4 grand. That would seem a little cost prohibitive to me for what your going to end up with don't you think. When he bought his back 2-3 years ago, they were well under $2,000.
