How much difference does it make using .223 vs.224 bullets accuracy wise?


I've used both diameters in both older (.223) and newer (.224) Hornets. I really never noticed any difference in accuracy and saw no signs of excess pressure using the 224s in older rifles. I have some Sierra 45gr 223 Hornets, I'll send you some if you'd like to try them in your drilling.
