For whatever it is worth I had Jack Rowe in Enid Oklahoma do a pre-purchase inspection on a British ejector gun. It was five or six years ago. Jack is an English emmigrant, gunsmith, formerly worked in the Birmingham trade, and has written some articles for the Doublegun Journal and used to teach a one week class on double gunsmithing here in the US. He may still for all I know.
I had AZoom snap caps with the gun when he inspected it. It was the first time he had seen them. He was very complimentary of the AZoom and said it was the only snap cap he had ever seen that he liked. He disliked the coil spring snap caps in particular and maintained that they fatigue stressed the strikers.
I have no idea if he is wrong or right. Just reporting what he said.
I agree with Doug's statement that the snap caps can and do dent wood on occasion.
I like Joe Wood's solution the best.
Best,
Mike
