Check Your Firing Pin Protrusion By Glenn Skipworth. A member recently had a mishap with a primer. After close inspection his firing pin protrusion was found to be too great. Question: Why would this be an issue you might ask? Answer: If the firing pin protrusion is too great you will run the risk of a primer being punctured and the result may be a heap of gas blowing back into your face. Eye injures may occur. So please check your firing pin protrusion to prevent this happening to you. Most of the service rifles we use will have Min and Max protrusion and you can have this checked with gauges designed for your rifle. If you are unsure of this please ask around the club and you can have this checked. Any alterations need to be made by a person qualified to do so.
