I bought one of those when they first came out.
It was OK but no matter what I tried, I could not get the electronic ignition to be any faster or more reliable than the striker ignited primers we have used for over a century. The ignition was more like a ''glow plug'' but not difficult to get used to. Every let off was a surprise.
I had it rebarreled with a heavy, match 30 cal, chambered for the 308Win. It never could be made to shoot well enough to win any matches.
Ignition was always positive. Not one misfire out of the 1500+ shots I put through it.
The trigger was a shooter's dream come true, that with very little effort could be modified to be well below the 8oz factory limit.
The only noticeable resistance to actuating the bolts was from stripping the round out of the mag well, which I never did, because I always loaded the rifle singly, without using the mag well. The follower and mag well had been replaced with a piece of high density foam.
Cartridge cases were just anything I could pick up of match quality at the time, same with powder and bullets.
The battery was just a 9 volt type, available from any grocery store. You had to remember to turn the system off, with the key after the match was over, or the batter would be dead by morning. Batteries could be depended on to last at least 16 hours, without needing replacement. I changed them before every match day, no matter their condition. I ended up with about 50, stacked on their bases in a plastic box. I used those batteries for years, after I got rid of the rifle, in my Chrony.
Primers were a different story. The LGS that had the rifles in stock, only carried factory loaded ammo.
I had to purchase the primers from a Remington distributor in Montreal. They were appx 3X the price of standard impact ignited, chemical types and I had to purchase 5000 per case minimum.
Everything on that rifle could be modified to go back to the normal Remington bolt action 700 platform. Most of the parts, except the trigger were directly interchangeable, without any further fitting.
Of course the bolt had to be replaced and properly fitted.
I traded that rifle to Noby Uno for a couple of Hart match grade barrels and a very precise reamer, that could be sharpened one more time, before it was used up.
He played with it in its original form for one season, then converted it to a standard/trued Remington 700 with a new bolt and stock.
I don't know if this is what you were looking for, but it was my experience with ONE of these rifles.
A couple of other folks I know, loved them and lamented the lack of cartridges they were chambered for.
