Bruce I am not sure how the monolithic projies would go and I think we would probably have to many people digging up the mantlets and becoming a hazard trying recover the bronze to sell to the scrap dealers....LMAO
Oh yes I have used surplus alright the good old P.O.F and grand stuff it is in fact it is so good you would think you are shooting a percussion rifle click --------wait--------bang---------and wads of confetti out the muzzle with a wishful thought of now where the hell did that shot go!!!!!!. As the other stuff headstamped WWII vintage Mk VII like MW, CAC, MG, RG and so on are now collectible unless you have a few 0000's rounds tucked away just too good to throw down the range.
