Odd that this popped back up to the top. I was just considering using ONLY the .223AI for all all of my deer hunting this year. Yesterday I changed bases on the rifle my 2 youngest use and will be sighting it in, shooting with them later today. I know I won't stick to only the .223AI....I like to use different rifles to much and over a 4 month season hunting 2 to 3 days a week I have trouble with my fidelity to one rifle.
I've had excellent results with the .223AI, 62 TSX/TTSX, and deer. Some of the kills have been with forming loads so in some cases the velocity would have been slightly less than normal .223 loads. Majority have been less than 100 yards and shoulder shots.
