Alex, my Russian friend, it is always good to hear from you.
Sounds like you have a good project ahead of you.
I am determined to do some work on 224 bullets and find out exactly how good they can be. I plan on using commercial bullets, swaged with 22 long rifle case jackets, swaged with J4 jackets and custom made bullets. I have all or near all the materials needed, and rifles adequate to do the testing (and tell the difference).
