I had thought of .270, but what experience i have, there is a hell of a bang, heavy recoil, ammo is expensive and dont seem to be that popular??!!. Is there a reason for this ??, dont know, i had thought of a 22.250, perfect for vermin, and yes, will take care of deer if taken in the right spot, but, correct me if i'm wrong here, are not suitable muzzle velocity or whatever it is they measure leagal deer calibres by these days.
So i still dont know.
