There's 20 plus AR chamberings other than .223/5.56 plenty capable of taking game at distance?

What bullets have you found that give good expansion performance at these lower velocities?Holes kill things period! At 496 yards with a 120gr Nosler Ballistic tip from a 6.5 Grendel 16" carbine. I have watched the bullet pass completely through a mature mule deer. Center punched the lungs, the buck walked backward for 4 or 5 steps after the hit and dropped. Done deal.Same deal at 302 yards on another buck, bang Flop! He slightly raised his head after he dropped and got another through the throat.

Taylor Knock Out Values were developed by John Taylor as a way to quantify the ability of various cartridges to ensure HUMANE ONE SHOT KILLS when an animal is hit in the vitals.Here is a site that will calculate them for you. This methodology was developed after having personal, first hand, experience shooting THOUSANDS of big game rifles. http://www.handloads.com/calc/quick.aspThere are other methodologies, but this one is one of the most widely accepted. Thornily is another widely accepted methodologyhttp://www.beartoothbullets.com/rescources/calculators/php/thornily.htm?v1=120&v3=.243&v2=2500One or two, or even a few dozen animals are not sufficient to make generalizations from.
