I currently have a tax credit in 6.5 chopped to an 18" barrel running a uni mount rather than the tax rail.

My local place has a bergara 6.5 ridge he got in on trade and we have talked about doing a swap (i would get cash in the end)

What are your thoughts?

I haven't done much prs with the Tikka since the chop and I would almost feel better of having the fps from the 22" bergara.

I would mostly be doing hunting with a little bit of plinking.

Enjoy, and do the prs, and hunting to the best of your ability.
My opinion is less than useless.
Pro tip. Do not jump from heights that might injure yer feet.

Screw a silencer on the Tikka and go hunting.
