Failure to launch

[pdog shooter]

Friends reload did not fire. All others from that session were good accurate loads. Primer did ignite, H4350 powder turned a yellowish color near primer. His process involves wax for FL resizing and then wiped clean. Dry brush necks and graphite lube. No liquids of any type used in process.
Got any Ideas?

Either bad primer or primer not seated deap enough and firing pin pushed it forward. When fire forming cases if you dont seat bullet in jams you'll get exactly this every few rounds

I always check the flash tunnel in the brass at bottom of primer hole for debris from the tumbler. Many Many times, I find corn cob remnants stuck in the primer flash hole. Use a paper clip to push them out while cleaning out primer holes and brushing out the necks after tumbling and before sizing and priming.

+1 : I do this plus added quick scan inside brass case to visually inspect to insure nothing else is left from tumbling. Amazing what small particle can do to raise pressure or prevent ignition.

Thats funny, I'll be sure to relay the thought

I second flash tunnel. Another reason i run wet tumbler

Johnny's Reloading bench did a 4 part video series investigating hang fires in his 6.5 creedmoor. He identified several factors, primarily low case fill or starting/minimum charge weights and certain brands of small rifle primers. Of all the small rifle primers tested, only the CCI 41 and Remington 7 1/2 were immune to hang-fires during the test. Here is a link to the final wrap up and it's worth checking out.

Have an outside the house reloading room. Left the brass and bullets setting on the bench for the night and came back next day to start loading. During range session had a misfire. Pulled the bullet and dumped everything out into weight pan from scales and a stinkbug was inside. A severely burned stinkbug! Had another one where a spider wss inside a case, had to knock the bullet out of the 44mag barrel! This is over several decades of loading, so not a regular occurrence.

Yep stinky situation. Murphy's law. If anything can go wrong it will. Just like the 2nd law of thermofynamics.....any system, which is a closed system, will always move away from order and towards disorder.

Must be some reason why when stuff dont work , they say it has a glitch or a bug in it.....

It appears I also cannot spell thermodynamics because my keyboard has a bug!

Good info, thanks to all

Ive had that happen. I started laying a rag over the cases in the loading block. Had a misfire yesterday in my AR, first one in decades. Testing 35 gr NTX and Reloder 7 powder. All shot well until the last powder charge. Was using CCI 41 primers. I heard the hammer fall and nothing. Extracted the round, dented firing pin, rounded primer, carbon inside the case. Pulled the BCG and sure enough, a bullet stuck in the bore. Bullet entered rifliling about 1 mm and stopped. My SWAG is too light neck tension since I used a mandrel and or bullet pushed back into the case during feeding causing gas leakage. Back of bullet heavily carboned. Thats what I get for not crimping. Case fill on that load was 100.2% according to GRT. Ill be reloading all those loads again and crimping.
