I have a question on Cryogenic treatment to barrels?

I have been reading about this, I fine lots of Pro's and Con's on this subject.

1. Do I gain anything buy doing this to my barrels and actions?

2. Is there a performance increase in velocity in a treated barrel vs a no treated action and barrel?

3. The community around cryogenic treatments is positive about this, for cleaning is easier on the shooter and barrel. Can improve on the life of the barrel are for rounds down range, tighter group sizes from it.

I am sure that I have more questions on this subject, this may have been done here already. I have been bitten by the Savage bug, and have acquired 20 some different configurations, needing help on this as I have some new unfired barrels.

Thanks for all who are helping me out on this ahead of time.

Shoot straight, be safe.
