As a good friend at Williams Gunsight told me, "if you are changing a Barrel. its very important if you are shooting for accuracy, get your Action Blue Printed"If you find a Gunsmith who runs a buisness and tells you he could do the job for $50.00, RUN! get the hell away from this guy, there is so much work to get it right there is no Smith in there right mind could do this job for that price. you need to have the most accuracy that you can get..even one thousandths of an inch, can throw you off target at long range..it may be on at 100yards, but when you shoot to 500yards you will see the difference. You will be way off. There are many reputable Gun Smiths that will read this post, please enclude your opinions. Keith.
