LT DAN 432m...nice shot...I'm probably not ready for that smile.
20 or more years ago I hunt mooses with 22-250...head shot from 50-100m and down it was...but sometimes hands shake slightly and wounded animal was on the run...
we do not like wounded animals on the run...therefore use slightly bigger barrel than min.needed and part of your trouble are gone smile
At least this is my motto...
270 win is nice caliber have use it for wild boar and works perfectly
