I’ve got a SBE that I use for ducks/geese and a M1S90 for “just in case”.
After breaking both in per the Benelli instructions, both of mine cycle the basic Wal-Mart cheapie, or light skeet loads fine. I’ve never had a problem with any 1 1/8th loads. Now after a couple “K”, the M1S90 shoots 1 oz 2 ¾ dram fine. Both digest my 16-yard trap/skeet reloads 2 3/4 Dram 1 1/8oz.
I lube my rails generously with Rem-Oil, and I clean/lube my recoil springs at least annually or whenever the SBE goes for a swim (whichever comes first). I also keep the M1S90 pretty trim with just an Insight M3X light on it.
