hey so not worrying about money what would be the best air gun and scope for killing anything up to a squirel or bigger
Not worried about money?? A Quackenbush custom.
Off the shelf, though, maybe one of the big (9mm - .50 cal) Korean PCP rifles.
I have one that I have posted about before that shoots the same slugs (185-200 grains) that I use in my .45 Auto. It shoots bullets at .457 more accurately, though. Energy-wise. it is about triple even the most powerful .22 air rifle. More power than a .22 rimfire rifle for sure.
But it all comes at way more than $150. Check PyramydAir.com and search under air rifles for Sam Yang and/or Shinsung.
And they are accurate. I have a red dot on mine.
And they are LOUD.

The readiness is all.
