Ok- the .44 held together and my hand, while spanked on the middle knuckle, is ok, but a bit numb. I did get some hunting loads and started there. Shot 6 hunting rounds and recoil was stiff. Then I tried 2 rounds of the Buffalo Bore and they actually didn't feel much worse. After these eight rounds I was done for the day. That's how I roll
The next day, i wanted to do some ballpark sight-in and see about the jump crimp problem, if any. It was dark and I illuminated the target with my headlights, so it was hard to see the sights. Plus I'm 51 years old. Group was about 4" at 25 yards, extrapolating through the sight-in. I switched to the Buffalo Bore. Sorry this is getting long.
To answer an above question, the reason I want to shoot these heavy loads is because I camp around AK and there are bears. My wife carries the spray and I carry the gun while we walk the dogs and hike around. This particular ammo is the minimum I consider wise.
The BB shot 6" higher at 25 yards and the group of 5 rounds ran the same 4" group. I was resting my hand on a 5 gallon bucket turned upside-down. The sixth round I examined for crimp jump and saw that it moved a perceptible amount, about 20/1,000ths, leaving about 10/1,000ths before it would have tied up the revolver.
The last guy to save his behind from a bear attack only got 4 rounds off with his .44 DA revolver--killed the bear but the gun tied up from crimp jump. He didn't get touched by the bear. He now shoots a .454.
I'm pretty happy with the gun. I'll practice lighter loads and carry the BB on hikes. Maybe rounds 5 and 6 will be something with less OAL.
Sorry to over-share.
