T/C Omega ?
 

Should I float the barrel on my Omega 50cal, or is that just for centerfires?

my omega shoots just fine without any changes. Unless you're having problems at the range I don't see where the need would be to.

The Omega barrel should be free floated when you got it. Have you done the Dollar bill test this is what I'm talking about Gunsmithing - How to Free Float a Rifle Barrel Presented by Larry Potterfield of MidwayUSA - YouTube You will only be able to go back to the 1st lug then it should stop. If you have no resistance till that point you should be good. I do this every time I remove the stock & reassemble. Like HM said if it's not effecting the gun down range I would not worry about it.:thumbup:

You can actually use some shims cut from an aluminum pop can or thick plastic. If its not moving around or anything, i think you'd be fine.

Synthetic stock however could benefit from using accra glass and bedding the lugs.
