This was posted on another site I am on and I thought I'd share it here.

That site will often not show pages for non members so I'm going to copy the main parts for you.
If your not familiar the Electra is a battery powered, electronic ignition made by CVA that is now discontinued. I don't know how prevalent this problem is or what exactly failed in the system but it brings us back to the basic safety rules and always pointing the muzzle in a safe direction. I believe I'd also remove the battery in this kind of gun until I was ready to shoot but I honestly don't know if that would be safer as capacitors and condensors can store a charge even after power is disconnected.

Last March 17th, I proceeded to get the CVA Electra out and shoot the load out of it and clean it really good. For those that aren't familiar with that MZ, it's an electric ignition MZ. It takes a 9v battery instead of a primer. Once you turn the gun to on, it technically waits for 60 seconds in order to take it off safety and fire the weapon.
Well, after owning this thing for about 8 years, it didn't wait. I turn the selector to on and lowered the gun and turned to go outside, then it just went off. I was holding the scope and stock at the moment.
The 250 grain power belt entered my left foot and expanded, taking out all my Transmetatarsal bones and leaving a huge exit wound. Don't trust any electronic ignition muzzleloader. I'll leave some pictures for you guys to see. They tried to save my foot for 2 months, but there was too much damage, so they amputated it. You really don't think losing half a foot would totally change your life."








Like I said above, I don't know how prevalent problems are with this model but it's a teaching moment on basic gun safety and muzzle awareness. I wish this fella just had to deal with patching a hole in the floor. If you have one contact CVA with any questions.

That is a more robust system built into aircraft, vehicle and ship mounted guns with the platform supplying power and plenty of room for the electronic controls. It would be hard to adequately miniaturize it for a gun light enough you'd want to carry in the field at a price people would pay.
Those systems have plenty of problems caused by exposure to moisture, dirt and other elements but the training program for them stresses regular inspection and maintenance. They don't get used and stuck in a closet or left behind the seat of a truck for a year. When they get used in training they get inspected and cleaned  before everyone on that crew gets chow. In actual combat use the crew on patrol will clean and inspect it every time they return from base. On boats it gets checked every day whether it was used or not.
That's how you maintain the level of reliability our military systems have.
