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

So I had a JP Sauer arrive today. Cleaned it up and love it. 6lb, 6oz. feels pretty nicely balanced. Also feels built like a tank, locks up like a vault, has ejectors, and still in pretty darn good condition for a gun of this age.

But I do have some specific questions (plus I'll take any general info y'all have) as follows:

1) the stock has a bit of 'haze' or 'film' at some spots it seems. Wood is great other than this... Any way to remove this haze/film without removing actual finish? seems it just needs a deep clean, but what is a good product to use?

2) the barrel flats clearly show imp. cyl and mod. choke, but when i use my choke gauge it shows imp. mod/imp. mod. why choked so much tighter than the flats read? I realize best way would be to measure actual diameters and such with a different gauge but I don't have that available to me. i need to figure this out b/c I don't know if i need a barrel guy to open these up or not. i need at least a IC/M gun for grouse and woodcock. Or I was even considering tubes...

3) as you can see on the choke gauge pic, there is a little rust at the tips of the barrels. this is really the only rust on the gun other than a spot on the trigger guard which i've cleaned good as i can with 0000. bores are brilliantly shiny/mirror. should i live with this rust on barrel tips or should i have a barrel guy shorten them by 1/2" to get rid of that rust and reset a new brass bead?

4) anything else you can tell me from the flats?

Thanks in advance!

Try different size shot & see how it patterns. Kerner-Anson platform and looks like from West Germany 1960.

You do not show the marking which gave bore size. Realize that choke is amount of constriction not an actual size so these "Choke Gauges" are mostly worthless unless you know for an absolute certainty the bores are to exact standard size, which very often they are not. Nominal 16 gauge diameter is .662" which converts to 16.8 mm. If your bores run smaller than 16.8mm then your choke diameters also will run smaller. As Raimey said best bet is to pattern them & see what you get.

I'll give you the simplest solution I know of for your stock haze problem. Go to Lowes or Homedepot and get a can of Restor A Finish in Walnut. Apply it to the stock and chances are the haze will disappear. Follow this treatment up with a good wax.

i have the similar gun which I believe to be a 'Royal'. Mine is choked extra full and full. I also have another 12 ga,model unknown and a 20 ga 'Royal' both are choked very tight. I do not have the right gauges at this time and rely on measurements somewhat as you do. My conclusion from the 3 I own is that they are choked much tighter than other UK of US guns I own. I am not sure if this is just the way Sauer chokes their guns.

Model VIII, I think. Nice gun. I'd expect a German double to be choket tighter than tight. However, the only way to say how a gun will pattern is to pattern it. You may want to consider spreaders; these Germans often pattern so beautifully - if tight - with smallish shot, that one simply can't bear to mess with them

Edit: on the other hand, German guns do have smaller bores for gauge than the world's average. That, as 2-piper noted, will mean that a modified for a larger bore diameter would be IC for smaller. And, why would anyone stamp choke markings - in English, and looks like in different front from the rest of the marks - if they were standard? So, patterning seems to be inavoidable.

That's a West German (thus post-WWII) gun from the proofmarks. Might also say "Eckernforde" and "West Germany" on the barrels. Appears to be a Sauer Royal, the highest grade W. German Sauer imported back in the 50's and 60's. (But it'd be more of a medium grade across the entire spectrum of Sauers.) Nice, stout gun. You shouldn't need to worry about what you shoot in it.

Thanks for the heads up, I will look for this product.

Not a Model 8, it is a Royal made in West Germany in 60' as indicated by Larry Brown. It's right on the barrels, but I did not photograph them.

As for the choke marks being stamped in English, someone on another site mentioned this also. It seems odd someone would go through the trouble to do that if they didn't actually measure the bores and constriction and open them to those measurements, no? As you noted, looks like patterning necessary.

Would the 2 3/4" also been added later or would Germany mark both 2 3/4" and "/70" for the chamber length in mm?

PLEASE don't cut those barrels for the sake of a tiny bit of rust. Polish it away the best you can, get it stopped, and forget about it. It's a hunting gun.
