G3

[ammo.crafter]

My 20ga Remington G3 gives a light primer hit every once in a while shooting sporting clays....about or 1 or 2 out of a 100 rounds of 7/8 oz Remington Gun Club. These misses are usually in the middle of the session.
And yes, I meticulously clean the G3 after each use including the gas ports.

Reusing these shells fire without a problem.

Hmmmmm?

Things to look at are the firing pin and spring, and the trigger group.

Light strikes are caused by a broken, chipped, burred, or worn firing pin, or a weak/defective firing pin spring.
Also check the firing pin holes in the bolt, and make sure a burr or bent firing pin retention pin in the rear of the bolt isn't sticking or dragging on the firing pin.
The firing pin retention pin has "splines" on one end to hold it in place.
The pin must be inserted from the bottom of the bolt, not from the top.

Check the trigger group for fouling, shell particles, burned powder particles, shot pellets, pieces of primers, other debris that may be interfering with the hammer or hammer spring.
If you find crud in the trigger group, liberally spray it out with Rem-Oil to dissolve and flush it out.
Shake off the excess, then stand the unit upright to allow the rest of the excess to drain out.

Thanks for the info, I'll give it a try. Frustrating that the miss fire occurs not ast the start of a round or the end of a round, but somewhere in the middle.

Dfariswheel is correct about the general causes for a light strike being a trigger group problem or a pin problem. Let's not overlook a more serious condition, the gun may be going into battery with too much head space. If there's a gap between the shell base and the face of the bolt, then the gap can result in a light pin strikes and failures to fire.

Have you noticed, do the light strikes occur randomly, or only when the gun self-loads (shots other than the first one)? Have you compared the primer strikes of: a singly loaded fired hull, a self-loaded fired hull and a failed-to-fire shell?

What I'm getting at is the bolt may close just a little differently from being released manually as opposed to when the gun does it automatically. It doesn't take much difference in the head space to get drastically different results.
