You all know that I shoot Parkers, however I have a "E" M97 made about 1943 that is near new. I was trying to shoot sporting clays today and my reloads were tough to cycle. Shooting WW AA hulls, 19.5 gr WST and 1 oz loads. Mild stuff @7400 psi and 1150 fps. Obviously there are tricks to the M97 I am not aware of. Any ideas?
