doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Tell me about this JP Sauer... plus general ?s

I think I follow the bore / constriction thing a bit, but probably not completely... I think most other guns I own fall into standard bore size category and/or are newer with tubes.

Would tighter/smaller bores (compared to standard) shoot tighter choke, generally speaking, or does it still depend on the constriction of that smaller bore at the end of the barrel?

Also, if I have 16 Ga Gun "a" with standard 16 Ga bore diameter and then I have this Gun "b" with a smaller than standard bore diameter, would it be possible to choke tube both guns with the same tubes? To clarify, I have had some 16 Ga's choke tubed by Mike Orlen, but those seemed to have standard sized bores and none required thin wall tubes. If this gun has smaller bores and I did decide to choke tube it, would it even be possible to use the same choke tubes or would you need to move to thin walls or how would that work considering the bores are smaller overall?

Not cutting the barrels, don't think I could live with anything shorter than 26" though I do like 26" for grouse woods. If they were 28" or longer, I would consider cutting it back to remove the rust.

For now, I've done as you suggested. Removed best I can (will try some corrosionx also to get better) and I will just make sure I keep after the rust / keep oiled.

In a previous thread we saw how the rib extension is placed on a LC Smith,

How is it placed on a JP Sauer?

You'll find, when you measure bore diameters and choke constrictions, that there's a great deal of variation from one maker to another. As for the 2 3/4", I'd guess that was added in Germany. Those Royals were imported by Stoeger (that might even be marked on the barrels as well). Therefore, the Germans were kind enough to give us Yanks something we could understand in terms of chamber length--especially back in the 50's and 60's, before we were paying much attention to the metric stuff. I had a Sauer 20ga from the 1930's, imported by Abercrombie & Fitch. That gun was also marked 2 3/4", right on the face of the extractor luggers. Once again, I expect that was done because it was made for export to the States.

The gun was made for export to US, hence the "English".As Raimey said,if you want to know the choke, you have to pattern it, the constriction alone doesn't mean much.Remember, in 1960 they still had fiber wads.The "leaf" on the flat is the house mark for Eckernfoerde(Kiel)proofhouse,even if it is not written on the barrels.If it had been made for the German market, the choke would have likely been shown as 1/4, 1/2,3/4, etc.Prewar they marked choked barrels with a crown W and didn't show amount of choke.

Thanks for all of the info guys. This is great...

Going to clean the stock up with murphy's soap then wax tonight.

Wow, that Murphy's really works. Cleared the haze right up. Followed by some Birchwood wax. Looks great!

that gun looks exactly like my Simsons........lol

Sauer-Merkel-Simson . . . looked like they all worked from the same design.

So I took the Sauer to the club today and shot a few pattern boards. It seems to shoot where I point for the most part, so that is good. Everything, including ejectors, worked perfectly so that's good too.

I have never really patterned a gun before for choke purposes b/c most of my barrels seem to be standard sized and I have a drop in gauge that's been pretty accurate (plus a lot of my guns have tubes). Anyway, I looked it up and shot 30" circles at 30 yards, but now I need help interpreting how open/tight you think these chokes would be. They are more open than I would have expected, I think? Or maybe I just suck at shooting at pattern boards.

Right (more open) Barrel, 7.5 Shot, 1oz. Fed Game Load, 30 Yards


Right Barrel, 6 Shot, 1oz. Herters Dove & Quail, 30 Yards


Left (more choked) Barrel, 7.5 Shot, 1oz. Fed Game Load, 30 Yards


Left Barrel, 6 Shot, 1oz., Herters Dove & Quail, 30 Yards


If this is inconclusive and I need to shoot more boards, let me know! Like I said, first timer here, both shooting this specific gun and patterning for determining choke purposes.
