My son paid for the material and I ordered bullets, cases, 223 Lee pacesetter die set and a couple case prep tools. He said his rifle is a 5.56x ??? and I should have bought that caliber. My local GS said 223 material would be cheaper and more available so I took their advice. Did I do right or wrong? Sorry for the bad post, I always complain when someone else does the same thing
You did the right thing. They are the same like everyone else has stated. One is a compressed load the other is not being the 5.56 the compressed load. the materials you purchased are right. You can use .223 data from your load book and use that to run through his rifle. All good!
