I had a Colt Anaconda in my hand the other day with the top strap, top three cylinders gone, frame broken on both sides cylinder latch and grips gone and the bottom of the frame looked like you took a B.F.H.to it. Supposed to have been a light load detonation from someone's reloads.The lady shooting it needed stitches. Don't know about detonation but I do know pressure when I see it and that one was blown with a lot of pressure.
And NO I DID NOT SHOOT THE reloads . Pulled them all down tonight. In my guns I shoot my reloads or my sons, and I taught him.
Kyode I agree manuals are guides, but they have the pressure testing equipment I don't have access to. They also can be wrong and I have a Hornady manual with a load marked out at Hornadys suggestion because it was a miss print and hot as hell.. If I want or need more power I would rather go to a bigger caliber instead of trying to force a smaller one.
