I am glade to see am not the only one to shoot a one.
I was at the range shooting cast 300-gr. Cast bullets from my 375 jdj when another hooter offered me the use of his Crony. I asked him to shoot my gun trough it but he was scared of the recoil. So I tried to. To our surprise both sky screens jumped about 4 feet in the air and the crony fell over. We picked it up and saw a nice .375 hole trough the face plate, trough the 9v. Battery trough all the inners and out the back and on to the target. 100.00 to fix it
