[QUOTE="fmuguira, post: 2043934, member: 27974"] Powder goes into case easily, not a compressed load.. around 95-97%. Load work up everything went smoothly, no issues. Then at later date as mentioned, same rounds left over from testing work up exhibit pressure with extractor marks on brass and snug bolt lift. Running CCI250 s with load as it’s a fairly large powder charge. We plan to pull a few bullets, reseat a new one and see if there’s any welding and fire the load as is. Also thought we might dump the powder on a couple, return it and reseat bullet to see if clumping of powder could be possible. Lastly thought we d vibrate a couple of the loads rounds and then try that. Then load new rounds with same lot of powder, same charge and shoot those. Aside from all the above testing that’s where some googling found a little bit of info and guys talking of powder bridging. All the above steps worth a try and we ll run everything with the LabRadar working to see what velocity info we might surmise. [/QUOTE]
