So, I now have Talkatap app...so here I go try this again:

The 300BO round looks small in the mag, ¤ yes, the rounds below it are .223 and are JUST FOR SIZE comparison not implying that you can or should try to chamber or shot 30 caliber projectiles through a .233/5.56 barrel ¤
Is this normal? I will be shooting through AR15 10.5in pistol & AR15 20in Bullbarrel.

Load data is included in this reply.

☆ unfortunately, due to unforeseen load issues (for hand gun) and an improperly reassembled slide (again, hand gun issue) I was not able to test these last night as I hoped when I post on the FB back-up page.
