My boy Shane, with a mule deer buck he shot at 340 meters with a 6 Creed-105gr Hybrid, last fall. Buck took about three steps.
That barrel has 2100 rounds through it, and still shoots 3/8".
Good critters as usual Pat....
While not as impressive, daughter shot a couple WT bucks with the shorty Tikka/6CM/108s this past season. Good performance as suspected.
What powder are you burning in yours?
