Thanks for the comments, Walt. I agree with you that the excess strength of some of these guns is not needed in normal use. However, Miller and I are not in a peeing contest, I am learning a lot from his recollections and knowledge. By the way, Miller, one of my Parkers, a DH Grade hammerless pigeon gun, was made without doll's head by specification and it seems to be holding up pretty well after 106 years. As you know, I will not be feeding it any proof loads to further test it. I stand by my statement that if the frame flexes enough to put the doll's head into action, the gun is gone. Both Olin's test and Sherman Bell's test are at least some proof of that.
