Off to our permission in Sutherland again in November to give the keeper a hand with sikas, hybrids , and old red hinds. Normally I can get within 150yds to take a neck shot but on the hill sometimes a 2/300 yd shot is required. Obviously this requires one into the chest, but they will still run thankfully not into cover at half light yet but it's sure to happen at some point. Anyway I'm rambling , I'm using 7 rem mag with hand load 150g nosler ballistic tips at approx 3150 fps and getting quite clean pass throughs, even after going through both lungs. Any suggestions on a bullet and loading with more 'anchoring' power?
