I would be quite comfortable with a 200 yd. shot( I feel thats not the limit with a 30-30 in capable hands, and eyes)on a Whitetail with my 30-30.
And thats my about my limit with any cartridge for a Whitetail.
Actually I do agree with this statement as opposed to the more misleading statement I said above about long range inefficiency with the 30-30. It is (your right) fully capable of long range shots in the hands of a skilled shooter.
