[QUOTE="Unofficial Gun Addict (UGA), post: 987871, member: 81139"] Interesting issue and one not to take lightly. I was going to recommend chronoing, but you've already decided to do it which is a good thing. Another thing I would highly recommend is backing off your powder charge, as well as backing up your bullet. Some guns are fine with bullets jammed into the lands... others aren't, and extreme pressure spikes are one symptom of a gun that doesn't like bullets jammed into the lands. I'd back off .015 to .020 from the lands... and I'd make **** sure that my chamber measurements were spot on. I'd double and triple check using a overall length gauge, and a bullet in a dummy case with the neck just tight enough to hold the bullet tight, but enough so when you chamber it, it can be pushed back into the neck. Then I'd compare my gauge results with the bullet results. By backing off the bullet and charge, you can then see what kind of primer response you are getting, as well as velocity which you can the compare against your load data & manual. Be interested to hear back on how this goes or you. This might sound lame... because you likely already do this, but eye protection would be highly advised. [/QUOTE]
