It's interesting you mention that; I've burned a lot of H414 in the 7mm-08 with 140s and CCI 200s and never had the trouble you cite, even in deep cold (-20� F and colder) temps. Those were always loads that filled the case well however.

(My usual loads in the 6mm I used quite a bit years ago were 100s propelled by H4831.)


My issues were with larger cases that didn't fill past 70%, and cold weather. Never had an issue with the .243, but I always used a Magnum primer in it, at least with H414. My fault, should have used a different powder in the larger rounds, but it made me paranoid. The whole click...boom thing isn't fun when trying to kill stuff.
