Do they work in 2 1/2" chambered guns? My 12-28 Lil Skeeters won't, gun does not close. I was thinking of turning the business end on my lathe to fit, but the shell might protrude. Anybody try to turn down Skeeters or Gauge Mates for 2 1/2: chambers?
I have Seminole 12-20 Chamber mates I use in 2 3/4" guns, I like those as they have extractors, just like short Briley sub-ga tubes. I have a Laurona o/u for the juniors and a pile of Wally-world 20 ga shells to use up, so we will use the Chamber-mates this summer.
One point, there are different thicknesses of O rings available, I could not get the Chambermates into the chambers, I called Seminole and they sent me a bunch of the thinner 0 rings at no charge, and they worked fine
