Took delivery thurs. of excellent condition "twin-single" pre-war Superposed. Originally choked full/full, currently opened to .012/.025. Has considerable cast which I like and my LOP. I've been trying to find (internet/Schwing) something on proofing of the 30s guns. I don't need a hunting load at the moment but I want to know if I need to load down pressurewise for a couple boxes of skeet loads. I've got a couple of cases of reloads w/ Nitro 100, running 1200fps. rated 1020psi. Can these guns handle that safely? If not, the only other powder I have right now for low pressure is IMR 7625 for 16 ga. Should I step back a grain or two to 1150fps w/ the Nitro 100 and get a pressure under 9000psi, load the 7625 for very low pressures in 12 ga., or should I shoot the stuff I've got loaded?

Jasck, for my low pressure loads, I try to stay under 1200 fps. I'm guessing you are using it in a 12 ga. I just bought some Winchester AA Lite powder, it's good for 7/8 oz. 1 oz, and 1 1/8 oz loads just change bushings. I haven't tried it yet but it is the same as the Winchester AA Lite load they sell.

7/8 oz. WAALite 12.8 grs. Win. 209 primer WAA12L Wad
1050 fps. 5,500 psi

The only difference is that their load is I believe 26 grams of lead (15/16 oz) and velocity is 980 and psi is 5600.

If you look at the Alliant site and Hodgdon site you will find what you need and more.

The Superposed was introduced after SAAMI specs were in force, so should be capable of handling any 2 3/4 inch shell out there (not steel).

For high-volume shooting at clay targets I shoot 7/8 ounce loads in most of my old 12-gauge guns, just to be easy on them and me. I load the Remington STS hull with a Remington 209P primer, the Remington TGT12S wad and Clays powder. Working from memory here, I think the load is 16.4 grains. It is in their book in the 1200 fps colume and gives 6300 psi. My mental state is such that I don't like overly fast or slow loads. My mind likes 1200 fps and everything I load is to that velocity.

P.S. As I've posted many times before, no one can tell someone over the internet what load is or isn't "safe" in a particular gun. Only a really "qualified" (and IMHO there aren't that many) gunsmith, with the gun-in-hand can do that.

Jack,
Well done on the twin-single, I'm envious!
I don't know the proof numbers are, but I shoot a late 30s SP with just bout anything, except the extra stiff trap loads. I prefer light loads, more for me than the gun.

Would JMB design a gun that couldn't withstand a millenium of American made 2 3/4" shells?

Dave,

I did much the same for skeet with a 30s $&$ 26" which weighed 6.5lb because it kicked like a light 16 with 1 oz. so 7/8 was a bit more pleasant to shoot if not quite as effective. I guess the 1925 SAAMI level of proof and service pressure applies to all the Supers. Bit fuzzy on this sometimes; thanks for confirming. I also would prefer not to move back to 1150fps; I need to get another jug of 12 ga. powder. I always end up with the cheap stuff like Promo or N-100. From the charge wgt., Clays sounds economical.

12ga Supers are not lightweights. You probably won't even get much recoil out of 1 oz skeet loads, although you can reduce it even more with 7/8 oz reloads.

Tried to buy one five yrs. ago from a fellow in Tenn. I dithered and it went elsewhere. This one on GB for several wks. Buyer in April bid it in 1090; reneged. Upset the seller a bit but he paid the GB piper and relisted. I let the auction clock run out on it once. Second wk of looking I decided it looked good enuf; put the starter bid on it; no competition. Couple notches above my expectations every dept.

No they're not lgtwgts. This one (which is pre-Lightning standard wgt.) and my 66 Lightning Trap both tip the scale at 7.6lb. Have later Diana Field which is heavier perhaps because of the crotch black which needs to be tunneled out a bit in the butt. The '37 skeet Super which I no longer have 6.5lb and maybe just a bit on the light side for me. But they're not Citoris either, which can be a good thing if you're not built like an interior lineman. Given enuf condition to look good (they all seem to go on and on in the function dept.) I think they're still a bargain if you have a bit of the antiquarian in you and don't find second hand repellent. What's not to like? Pete from Bend will tell you that the long radius, round knob grip is just about the best thing ever. I've always been partial to the wraparound checkering on the Supers and A5s altho I've never been particularly fond of actually shooting the old "hand canon". The forend is special maybe because the Japs couldn't wring the cost of production out of it. JM and the twilight of the Belgian gun industry; interesting combination.

Postoak: This is exactly the sort of target of opportunity which fills the void when you can't find that "ideal" Manufrance. Oh well.

Do both triggers work as single triggers or just the front one? Have heard of guns set up both ways, but don't recall which Browning used.
