RE: WHAT SIZE SCOPE?
On my 22-250 i've a 6-24 x 56 and the 17 6-20 x 50
and on my deer rifles schmitt & bender 8x56
I only ever used a 4 or 6 x scope but now I wouldn't use anything else also I only use swavroski or shmitt and bender scopes they are totally reliable also try night force scopes they are good.
I shoot a lot at dusk and daw also with a spotlight so you need a good light gathering scope.
The clarity on these scopes is unbeatable and the back up service if ever neaded is second to none, It's a bit more money but it's worth it kit like this can be used for generations
