I would pick the bergara. I've put together a couple different bergaras including a 7RM ridge on a chassis for myself.
Nothing but good luck. Smooth setups, easy to find a load for. I also like that the 7PRC in bergara carbon barrels seem like they are all 22". That would be a great combo with...

I have a Sirui Am-284, I was happy with it for binos and light rifle work.
I did not like how short it was. I installed a riser on it, and it just made it too funky to carry. when I bought my Leofoto with the 55mm head, I was quite surprised how much difference the leg diameter made for...

My plinking rig that I use weighs about 14.5lbs in 22-250AI. My hunting 6.5CM is right at 12lbs. the 6CM shorty is right at 10lbs. My 6.5PRC comes in at 13.5 lbs.
