Glad your OK!
Be careful with your 110 grain loads as well. I assume the 110's are JHP's? the 125's are only 15 grains heavier (while this will increase pressures, so will the added (copper over lead) resistance of pushing the jacketed 110's). So be careful!
I'll stick with my 4.1 gr. of 231 in 38 special cases with the 122 gr lead bullet.
I personally never did see the use of a 357 Magnum J frame.
But to each his own.
Very glad no one was injured.
Allen Frame
The "J" frame is one of the strongest frames out there! Bolt notches between the chambers, just like the 5 shot "X" frames, Freedom Arms and other firearms that handle the real tough stuff. The barrel shroud is almost nonexistent which means that a forcing cone split is next to impossible!
Now, alloy frames, different story but the M60? Stainless Steel through and through? The 357Mag in no way is going to test that frame, no way.
Triple charges of fast powder? Yep. Chasing stuck bullets with full power loads? Um, yep. A firearm "stress tested" by another owner and you pushing the envelope a bit? YES! But just because they are small doesn't mean that they are poorly designed! My, my!
I will take a 357Mag "J" frame LONG before I would take a "K" frame 357Mag, ANY DAY!
The "L" frame will take a standard 357Mag all day long, for longer than you live and not have one problem. Still, I would stake my life, and have, on a "J" frame in 357Mag.
Two things I would check that I have not seen mentioned.
1. Pull the bullets on the remaining loads and weigh the powder with an actual scale. and are you sure it was a 125 and not a 158 gr bullet that slipped in?
2. Are you SURE it was Unique? Check the powder in the pulled loads to compare. It has been known to happen that some people have more than one powder on the bench (a reloading no-no) and use the wrong one.
Look on the bright side, you have some spare parts for the next M60 once you take off the sideplate and remove them, along with the grips and maybe barrel.
By the way the cylinder release no longer works and I can't open the gun.
I have a policy of only having a one can of powder on my bench at a time the rest is kept in the wooden chest on the floor.
So a little JB Weld on the cylinder-clamp the frame in a vice, put a 2x4 on the topstrap and pound it back down, heck you're good to goHere is why you never change components when reloading. I had loaded up some 110 grain 357 magnum loads. I ran out of bullets and used 5 125 cast lead bullets to finish off the box. So I took my Ruger 77/357 and fired two of the 125 grain loads through it with no problem. I then put the three remaining 125 bullets in my model 60. I pulled the trigger and you can see from the pictures what happened. No injuries to me other than a small cut on my finger, no one else was hurt. One part of the cylinder was laying on the table by my hand while the other along with the rear sight were about 5 feet off to my left. The other two 125 rounds unexploded were found some 10 to 15 feet to my right side. I'm am glad that Smith makes such well made revolvers. By the way the cylinder release no longer works and I can't open the gun.

Better yet-list it on gunbroker "good honest wear"
