The 648 is a 22 Magnum revolver. Were you shooting 22 Long Rifle ammunition? I do not think you can shoot 22 LR in a 22 WMR with 100% reliability.
New M648 fail.

Your right, I do not believe they make a CCI mini mag in 22WMR They do make a MAXI MAG
You would certainly end up with powder debris and possibly bits of brass everywhere firing 22lr in a 22 mag.
Notice that it has been 2 days since the OP posted last. Be nice tto hear what he figured out/

Re-read it, he does say Maxi-Mag.
Yes, but it would be easy to confuse them especial when you try them in "several bullet types"
It could cause debris to get blown in the wrong spot in short order.
If so the OP wouldn't be the first guy that did it.

All good thoughts but I still say don't mess with it, send it back. Good luck.
Sending a gun in just because it is fouled is a waste of postage and time. It isn't that hard to make sure it is clean.
But, as we have heard nothing from the OP in 3 days, I am betting the op did just that and his 648 is off and running

Been busy.
Looks like I have it figured out.
I changed out the firing pin for an "extended firing pin" from Apex.
The gun was still experiencing dead snaps on D/A. S/A it was working perfectly.
As stated before the strain screw came from the factory tightened all the way in. I thought I would try to get a shim in between the screw and the mainspring. I was going about it wrong trying to wedge something in there with the strain screw removed. Then it dawned on me to try another tack. Leaving the strain screw all the way in I placed a plastic piece between the mainspring and the frame up above the strain screw.
Then backing off the screw. The mainspring remained far enough apart for me to easily place a small brass shim where the strain screw contacts the mainspring. Then retighten the strain screw and TA DA!
It worked.
Took the gun to the range just now. Perfect operation for 50rds fired.
D/A trigger pull is stiffer than it was but not unbearable. With use it'll slick up even more.
Just for learning purposes I did try to fire 22LR round in the 648.
It would not fire any of them. It appeared the 22LR round lays too low in the firing chamber when the gun is held in the normal level firing position.
The firing pin strikes just a tad too high on the 22lr rim.
Maybe if I held the gun upside down it might fire? LOL

Glad to hear the shim worked. I'd be concerned with it falling out.
What most people do is take a spent primer, pry out the anvil inside then use a punch to flatten out the firing pin dimple from the inside. The empty primer cup will fit right over the unthreaded tip of the strain screw. The primer cup can't fall out, so it is a good permanent fix.
The Apex extended firing pin is not for use in rimfire revolvers. If it is still in the gun, remove it and put the factory pin back in place. Otherwise, you risk damaging the cylinder.
From the Apex web page: Not for use in rimfire model revolvers.

Go to ACE hardware many of them have an assortment of gun screws. Get an 8-32 screw with the correct head. It will be to long, but you can grind or file it to the length of your original screw plus the thickness of the shim.
If you get a couple 8-32 nuts and tighten those on the screw you will have something to hold it in a vise with while filing and when you remove them they will remove any burr from last thread.
