This is my first attempt at converting 223/556 into 300BLK. I used my newly concocted lanolin & Heet case lube & let me tell you it is SLICK!!!
I ended up with over 150+ cases that passed the case guage test & 21 that didn't so they got thrown into the recycle bucket. I used different headstamps for this operation & it seemed that the 223 cases formed a bit easier than the 556 (slightly thicker case is my guess).
I used different headstamp case's that were shorter than 1.748" (I have thousands trimmed at 1.750 to reload my freedom bullets)...
