Going to bring this thread to the top again. Had a good gunsmith measure the chambers on this 16 ga. They do indeed measure at 2 3/4....... Whether or not they are factory standard is anybody's guess. But they are not marked. What is unmistakeable is the long, smooth, transition from chamber to bore. As with the chokes.....So perfectly honed, and polished;
someone at the factory knew their job well.
And speaking of chokes; this gun reminds me of a 12 Ga. JP Sauer I own, that has extremely tight chokes---extra full on the right barrel, and a lot tighter on the left.
I set up a target at a taped 25 yards; and the more open barrel of this Elsie put ALL the pellets from an RST #71/2 PaperLite into a 12" circle! Gonna' be a little tight for skeet..... My son and I kicked out a few clays with the Trius One Step..... Now he wants to try a few rounds of trap at the local sportsman's club.
Once again, thanks for all the responses to this thread......
Going to go find a few more old ladies' closets to plunder..
Grant.
