Remarkable, Thanks for your input on my cast and drop questions. Since I am strongly left eye dominant, I believe the left cast will be fine. Per your instructions pertaining to drop, I have ordered a stock drop assembly kit. With the reversible drop plate i can get C SX - also the C drop shim is supplied. Right now when I shoulder the gun normally, I'm seeing way to much rib (not flat)-so I think I'm on the right track with more drop. A few years back I was having a problem with the gun cycling,and stovepiping spent shells. I came across your info on the forum. Got a Wolff 25% extra power spring and cleaned and lubed the tube with break-free. Now part of my yearly maintenance - Haven't had a problem since. Thanks again for responding, Benell's really fortunate to have a guy with your expertise on the the forum.
