Manual Reset Jewell Trigger Test

[Mike Marcelli]

Dave, one idea I think would be worthwhile would be the elimination of the conventional firing pin/spring assembly with an electronic striker assy. Imagine a conventional bolt with a small solenoid threaded into the bolt body using the bolt shroud threads. When released, the solenoids plunger would drive a very short firing pin tip through the normal firing pin hole. This small pin tip would be lightly spring loaded for retraction after being actuated. This type of firing pin has been around for many years in single shot rifles like the Browning B78 where it's activated by the falling hammer. The 'trigger' would simply be a switch mounted in the conventional position. For a power source, a normal 9 volt battery would seem to be the way to go...but maybe one of the coin type batteries would be a possibility?

A setup like this would allow the use of conventional primers, which was the major downfall of the Remington EtronX system. These rifles also had a pretty sophisticated electronic board to allow a functioning safety, a 'low battery' indicator, etc. None of this would be needed for our uses, of course.

The beauty of a system like this is that it could be a refit into existing actions and would use the original bolt.

Just my ideas for improvement on a windy South Dakota morning. -Al

The technology exists, it would needed to be adapted.

With all due respect Dave

A lot of those marks come from lifting the bolt handle after firing. I agree that to sloopy a fit can cause problems but I'm discussing custom actions here. What can we improve on in the ignition system? If the clearence between the bolt and the action is that bad then that particular action would be considered for use.

I am talking custom actions too. I can see the bolt lift up when I close them up. I own 7 custom action BR rifles and most of them have a definate lift when the bolt closes. I just checked them and two of them don't seem to have any noticable lift when the bolt closes but a couple of them seem to have a lot of lift. The one with the most marks seems to lift more. Wonder if the action- bolt fit may be more on that one?

I can see that the marks are the result by opening the bolt.

I think 90* sear-cocking piece engagement surely wouldn't hurt anything.
