I loaded up a few rounds of 300 blkout and they will not fully chamber. It appears the bolt isn't going into full lock and when I go to eject the shell it is very hard to eject. Some of the rounds will fire most take a second try to get them to fire. I tried a factory load and it chambers and ejects like butter. I have tried just cases and it's still a no go so it's not a bullet or oal issue. It appears that the shoulder is a tad higher then on the factory load but it's impossible to measure. Could I possible have a bad die?
