300 BLACKOUT 150 GR. RN FAILURE TO SUCCESS (SORT OF)

I try to document my testing and experiences with the 150 gr. RN (Hornady Interlock) bullet and 300 Blackout. I purchased these bullets for use in the 300 Blackout AR-15 type upper and just couldn’t get them to cycle reliably. The following conclusions are based on viewer comments and further testing.

       5.56 top/300BLK bottom                                    5.56 left/300BLK right

I enjoy all things outdoors and gun related. I am a life long hunter and staunch supporter of self defense and the right to keep and bear arms. I am a Concealed Carry Instructor in the state of Kentucky and enjoy helping people exercise their Second Amendment Rights. I also enjoy collecting historic firearms and recently started reloading ammunition.
