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.
