Hard to find . . .
I did a little bit of research on the web on the AK-74 and the three or four places that I read all mention the design of the 5.45 x 39 mm round incorporates the mild-steel core to enhance the tumbling effect of the projectile when contacting soft targets ( like human tissue ! ). So, I might never be able to shoot this particular rifle at an indoor range. Maybe somebody in here that knows about handloading can clarify this more, I hope. I was planning on using the rifle at TR in Oregon next year, but they have a lead-free range, and TTI does not offer my caliber. Gonna have to use the heavy SOCOM, or the M4 unless one of you guys hands me an idea !
