I was thumbing through Lyman shotshell manual and found a heavy field load I used to use . 1-3/8 oz. , WW571 , AA 2-3/4"hull , WAA12R wad ,WW209 primer. I thought , hmmm, I wonder if ? I whipped up 5 cases , weighed 12-.311" ball cast of wheel wt. which weighed shy of the 1-3/8 oz. , stacked them in and got a beauty of a crimp ! I'll shoot them tomorrow an see how they fly !
For grins I looked for 571 powder to check price as mine is marked $9.39 Guess what , I cant find any !! I just have 1-1/2 # left Wonder what replaced it ?
