I don't hunt at the moment but have 9 rifles only one is a Pcp.
I have found that 30 yrds is best for me in n both calibre's
The v reason being in .22 that gives not far off a 10 yard secondary zero and relativity predictable curve.
In .177 with the right scope height to power etc I can go from 17 to 40 yards with hardly any difference .
But the biggest factor for me is you can still see 30 yards accurate enough to set up with down to 6 x zoom I find it cc a bit of a struggle to get pellet on pellet with 4x at 30yards so do go back down to 25 if that's the max the scope can do .
