Last stage of todays (small) 3 gun local match .
Probably 75 rounds deep into a 150 round batch that I had loaded for 223.
24 grains h335 (fills enough of case, cannot be a double charge)
-hopper only used for rifle powder, and was in the middle of the whole box I loaded
OAL 2.240 (crimped at cannelure, light to medium).
CCI primers
OAL checked with calipers following size/deprime, <1.755, chamber checked with Lyman case length headspace gauge
Loaded on Lee Turret Press
Checked with Lyman OAL loaded round chamber checker (the orange one) prior to putting in my ammo box after loading
On my computer, frame by frame, at the detonation, you can see bullet impact in the berm. After pulling bolt, barrel is clear. RO and I heard clean click, confirmed later by the video, thinking less likely squib. Unable to determine if the round that was cleared in FTF malfunction had a bullet in the casing. Too many loaded rounds on ground from people clearing the stage.
Of course, first question is always 'are they reloads'. Yes. But upon inspection by some people more knowledgable, they think possibly some sort of failure to fully go into battery (is not a fancy or $$ upper/bolt, Palmetto State Armory), causing detonation out of battery due to some less than ideal tolerances. Hard to say tho, cause gun has been through ~2k rounds
Was not a slam fire. I pulled the trigger.
PIcs coming from my phone so they aren't huge
Any thoughts on diagnosis? I want to obviously be sure things are less likely to happen again (after i beg my wife for the next 12 months to let me get a new rifle
