CRITERION 223 AI BUILD
Steve M. of South Carolina sent us some pictures and info about his 223 AI build using a Criterion barrel purchased from Northland Shooters Supply.
Here as some of the specs for Steve’s build:
- 26” Criterion Barrel- MTU Contour- Small Shank Savage- 223 AI- 7 Twist with muzzle thread
- PT&G Headspace Gauges
- MDT XRS Chassis
Here is what Steve had to say about his build:
“The action is a factory Savage model 12 action and it’s sitting in a MDT XRS chassis. Timney trigger, Omega 300 suppressor, Vortex Viper 5-25 scope.
The load I shot those groups with was as follows:
- 77gr SMK
- 25.5gr V-N140
- Starline .223 brass fireformed into .223AI
- Federal 205M primer
- @3000 fps
I have been able to push that bullet/powder combo well into the 3100’s but it shot best around 3000fps so that’s where I left it. I have since switched over to the 80gr Sierra SMK bullets and it also shot best at 3000fps.”
