There is never any reason to abuse an action like that.
Exactly the way I see it and I never could understand why so many people think they have to jack-up the performance in everything they shoot! Many personal injuries have resulted from this as well as the destruction of many fine old guns, a lot of them very desirable collector guns. I think that is what made me post this in the first place, just seeing that well kept (until now) original High Wall mistreated like that just didn't sit right with me. The Italian replica I have coming soon and (hopefully anyway) a custom built High Wall will never see anything except what they are meant for. I have nothing against shooting high power loads IF the gun is designed for it and apparently the new High Wall models, Browning and Winchester, will safely digest about any sane load a person can put in them but an old original?
Red Pepper, I didn't find out what the powder charge was he is using but unless I am seriously mistaken I saw what appeared to me to be some very obvious warning signs, most notably the sticking cases and horrendous recoil.
