I used the same rifle, a .54 cal Knight mk85 for this cow elk in Idaho. The No Excuses .54 525 grain bullets shot extremely well in that rifle. This cow was hit in the left shoulder, bullet went through both lungs, broke offside shoulder, and was found under the offside hide. For my area this is a large cow, live weight Im estimating just over 500 pounds. For reference, Im 6-3 and weigh 250 pounds.

Manny
