Nice rig in a very useful configuration. I like your scope set up.
I have a short shell adaptor for my Mec 600 and reload all my 16ga shells to 2 1/2", they work fine in 2 3/4" chambers also, and never have to sort through ammo to make sure I have the right shells. Components have been available from BPI and Graf's. I fold crimp all my lead loads and roll crimp my bismuth stuff easy to tell the difference even in the dark. I shoot 3/4oz bismuth and 7/8 oz lead target/light gamebird and 1oz NP BB's for coyotes/predators.
