I am a greenhorn at this. Age and preference seems to be telling me to go long. I recently purchased a Winchester Coyote in 7mm WSM. I dressed it with a 6X24 target scope, had a muzzle break installed and some trigger work done. It shoots on average less than 2" @ 300 yards. Am I asking to much to think that this could be used on deer out to 800 yards? Please don't laugh! I am willing to listen.
