So I've heard a few times about folks opening the bores up some and using steel ok, but I've never heard how the forcing cones respond. Mr Singer, have you noted anything amiss with those on your Hercules? I'm inclined to do the same with mine on ducks too. It's been opened to Mod/IC, and the chambers are a bit longer than 2.75".

I have had no issues with mine. I have used it with steel for about 10 years. Probably about 3000 rounds of steel hunting have been fired though it.

You are already well aware of this, but I would never recommend shooting steel through an older gun with a full choke. In many wad systems, the shot column is wider than a full choke bore. There are two issues that develop. First is scoring or damage to the choke. Second is a ring bulge behind the choke. With a double barrel, the ring bulge can cause the soldering on the ribs to fail.

In the past few years, I have repaired/soldered 2 SxS ribs and lugs that failed. Neither of the guns were my own. Neither had been used with steel shot. One happened to be a 16 NID with 2 5/8" chambers that had been repeatedly fired with modern 2 3/4" ammunition.

You make your own decision whether or not to use steel in your gun. I know this, an old Stevens was never meant to be a safe queen. With my own gun, if the ribs were to separate, I can repair it and would enjoy doing it.

Another choice, if you find cyl/cyl too limited is to have the barrels jug choked. Material is removed prior to the muzzle, leaving a final effective constriction. Sk/IC is most likely possible, skt/skt almost certainly.

The up side is your not effecting the terminal end of the bore, and poi should not be affected. The gun is not visibly altered, and the cost is less than choke tube installation. Something to consider is ammo selection can’t get you the results you’re looking for out of cyl/cyl.

Well I've had my new old girl in hand for three days now. Made some measurements and checked bbl regulation. Made some interesting findings. The two sxs cylinder bores measured cylinder on right side and slightly more open on the left bbl. These measurements were taken with a choke guage stricktly looking at muzzle openings. I do not have the tools to measure the inside bore ahead of choke reagion, so these choke assignments may not be true.
The pattern board was very interesting. Using RST factory loads of 2.5", 7/8oz, #8, shot into a 30" circle on board from 16 yrds, and 25 yrds. Results:

16 yrd, Right bbl, 99% in circle @ 20" dia.
16 yrd, Left bbl, 99% in circle @ 15" dia.

25 yrd, Right bbl, 90+% in 30" circle
25 yrd, Left bbl, 99% in 30" circle, with 90+% in 25" circle.

Do these results suggest a typical cylinder bore? Clearly whatever it is, the left bbl is shooting tighter patterns with this load, even though it measures more open at the muzzle. I'm very pleased with these results, and do not feel like I will be "spraying and praying" with these patterns.

Generally speaking cylinder bore is expected to deliver about 40% with a standard lead load at 40 yards. This varies with ammunition quality, velocity, and shot hardness of course.

40 yrds is a ways out there. That's about max for typical late season doves. Will try and see what the count is.

in spite of what you see , it sounds like the left barrel has a little choke of some kind in it . Depends , but that might be the cats meow . Barrels shoot together !?

Regulation is satisfactory for the shorter ranges certainly. At the two distances I've shot so far, 16 & 25 yrds, I see a slight favoring to the left with the left bbl, and slightly right with right bbl. They do not appear to be set to converge inside that distance. Right bbl does favor center at 25 yrds. But with so few shots taken so far, too soon to say with confidence if either side is wondering. Will see what happens at 40.
