my son had my AR10 out today. came in and said did you do some thing to your gun ??? why ? the mag full of steel case stuff i gave him wouldnt go off. looked like light primer strikes. went and loaded up a mag with some hand loads and no problems at all. any ideas or just junk the 50 rounds of the junk ammo ?
Has this ammo been a problem before? It could just be hard primers. No real fix for that without messing with your trigger pull by stepping up your hammer spring.
If this ammo normally works for you, might check to make sure the hammer spring is installed correctly, with both legs on top of the trigger pin. Of course make sure the FP is not bent or damaged, crud in the bolt, or even burs or peening around the FP hole interfering with the FP. Since you say it worked fine with other ammo, I'd say those last few are unlikely.
