Just double checking your numbers Sheepdawg. I seem to remember I needed at least 40gr of Lilgun in my 16" Bushmaster factory upper, just to stop hangfires. And I think at least 36 or 38gr of Lilgun in my Tromix. That's using .451 bullets, and having no pressure signs. Although, you mentioned the Side crimp, which I don't do on the pistol bullets.


I experienced no hangfires with my Hornady 230gr FMJ, Starline brass, CCI #41 srp, 37gr Lil'Gun, loads using a Lee 450B Factory crimp die adjusted per the Lee instructions. Given the light weight of my 450B rig my latest order to MidwayUSA included a PAST Mag Plus Ambidextrous Recoil Pad Shield . Sadly I live in California, it used to be a great state, where there is pending legislation to ban mail order purchases of gun parts, so I shot off an order to Windham for another 450B magazine an spare bolt assembly.
