Johnny's reloading bench YT channel did some testing on Shooters World powders with 223. Video was informative enough for me to give it a try with 224V. I reviewed Shooters World loading data and ordered some Long Rifle and Precision powder to try out. Match powder didn't have data for heavier .224 bullets so I didn't bother with it. Also just got some of the new Win STAball 6.5 to try out in 224V. Will try and post some data when I get some results.
