I've had this happen. Reloading 5.56 ammo using an excessively light charge of H335, and a non-magnum primer. An experimental load using 40 gr 223 bullets and extremely light charges for a no-recoil 3-gun load; because I got the components for darned near free, and was curious if: hmmm... can I game this? ![[Image: smiley_smartass.gif]](https://www.ar15.com/images/smilies/smiley_smartass.gif)
Turns out, didn't really work, as a light charge of military ball powder with a standard primer, doesn't build enough pressure and energy to light. Fixed by switching to a magnum primer, and eventually also upped my charge, but didn't need to once I switched to CCI41's.
My best guess is you have a light load, either by design, or maybe that round got a light charge somehow. What was your target charge of the H335? Alternatively, how do you prepare your brass - wet tumble? Sure it was fully dry?
For what it's worth, H335 is OK, but for ball powder I tend to prefer TAC, and really, I tend to prefer 8208 over both for most things. I'm also running CFE223 a lot more now; though I'm not sure if it's the best Grendel powder, since in my experience it runs best at high pressure, which isn't the life of the Grendel. But I'm still experimenting and learning on all of this myself.
I also am sitting on a batch of foreign primers, that all hangfire. There's literally a 1/10th to 1/4th second ignition delay when I run that batch. Tried numerous loads, and numerous runs, and they do it every time. Manufacturer replaced them, but I still have the bad one, that I'm not sure how to even get rid of!
