[QUOTE="budlight, post: 2563737, member: 2939"] I'm going to go inspect it. Rifle length gas tube, so you wouldn't think it was gas tube induced pressure. He used a cheaper PSA BCG and lower kit. Hodgdon list 24.4 of CFE as max load and he was at 27.5 gr. He told me that they were all 2.26 COL. Maybe he had some small case volume type brass. 27.5 of cfe is a pretty full case and 80 gr is longer. Probably making for a very compressed powder load. 90 degree day. I've popped primers in the past in various rifles. I wonder if over time because he said that rifle has been shot hundreds of times previously that the BCG developed cracks. Look at the sheared point in the picture. The BCG is a hollow tube and the metal is thin near the sliding guide area that came apart. The mag well is definitely explosion expanded. Scratching my head on what is going on. [/QUOTE]
