I’ve used a 6.5 creedmoor and I was very impressed with it, the distance it shoots out to and how accurate it was out to them distances was unbelievable, it’s almost to much rifle for any shooting situation ( this is just my opinion, please don’t pick on me to much ? ) like FH said .243 to me is the ideal deer calibre for what we shoot around here, if you were wanting to go bigger animals then the 6.5 would be what I would go for ?
