Might not be the best choice if you don't reloadDivey wrote:.220 Wilson Arrow.

My vote would be .223 if you want cheap, available ammo, or a .204 if you want to flatten the trajectory for longer PBR.
Just my opinion

Davyd, thankyou for your advice.Davyd wrote:.223
I would not do a light though - for those ranges a lightly heavier rifel helps in both sitting firmly and being able to see your shots - hence walk your bullets if you need to.
My furthest rabbit was 450m on the second shot with Remmington 700VS and factory Remmington accutips 50gr bought second hand for $1500 a number of years ago. I now use a much more expensive Blaser R93 but being lighter I am not sure I could readily replicate that shot and have more difficulty tracking my shots as I lose the sight picture more when I fire.
