For mostly sub 200 yards I'd take the lower recoil of the 130s over the higher BC of the 147s. Prepare for substantial damage from either of them at those distances.
I don't know what brand, its what I grabbed laying around my buddy's shop. I'm sure any of the 3M style 1/8" thick will do. Its been to swampy Alaska, PNW in winter, frozen/ deep snow, and 100F+ and been fine through all that thus far.
lighty used Spartan Pro Hunt Long bipod. Comes with standard rifle adapter and all mounting parts, plus an additional standard rifle adapter and mounting hardware for use with multiple rifles.
$240 shipped.
It seems to already be far better than my A-bolt, but we will see given time and lots of use. I've had so many issues with that rifle, it's hard to even look at a Browning.
Random question as I don't know much about gunsmithing/chambering: can a freebore reamer be used through the action without removing the barrel? Curious if extending freebore is an involved activity or simple.
