Federal ammo with a 180gr spitzer, .303British, from a No.4Mk2 wearing all its wood and a Weaver K2.5x on a Cad-Technik mount. Range was paced out afterwards at just over 200m, which is longer than I would normally try but the mule doe was as much a novice as I was and she gave me time to get prone and work up a nice position.
