tks - I was wondering what happened.

Like I said, I'd shot 500 or more of the heavier loads without any problems. I locktighted all the screws before shooting it as I'd had loosening screws on my .375 Big Bore with loads very much sub-max.

Each to his own on loads. I loved shooting 300's at 1,584 and on up to 340's at 1,740fps until I ran out of that particular powder. Those loads were very carefully developed using new brass each time to eliminate any case hardening from ruining the pressure measurments. When I found them safe, I thoroughly enjoyed shooting it, a lot.

A hunting buddy wanted it for his wife for moose, so away it went.
