Plugged flash hole IMO. Weird.
There ya go. Keep things simple. Less opportunity for Murphy to call The Law on ya.The brass polish theory makes sense to me. The first 31 reloads were done with brass that was cleaned without polish. All fired fine. The polish arrived later and was used for the batch giving me problems. I'll dump the old media, use new, skip the polish and start over with "new" brass.
I visually checked every case for powder before seating the bullets. There was quite a bit of unburned powder left on the cylinder face from the squib as I mentioned in original post.Sounds to me like no powder, just primer.... unburned powder could have been there from previous rounds.
Maybe I should try a couple with a tighter crimp. I was trying not to over crimp the plated bullet and was under the impression a light crimp was sufficient. I suppose the worst would be poor accuracy/ fouling if I overcrimped the plating? But there's something amiss with lot unburned powder left from a squib and your "best guess" is worth a try. There were a few others that sounded weak also and I very much doubt I had powder dumps that varied that much because I was using an abundance of caution. Is there any reason I can't go back and put a tighter crimp on some from the bad batch? How's the crimp(Lee fcd) look in my pic?My best guess is not enough crimp, meaning not enough pressure built up to completely ignite the powder, leading to your squib. Post a pic of your finished rounds and somebody with more knowledge than me will show up with an answer.
