Home Forums Hunting & Shooting Combination Guns and Drillings Help with new to me drilling

Wondering if one of you guys could help sypher the proof marks to help with chambering and load info. Also hoping for probable date of manufacture and this thing has a crazy safety system (stalking?).

Thanks Chris

We need PICTURES, overall, barrel flats, underside of the barrels infront of the flats, water table, top of rib and sides of the barrel. All of these contain markings or style of markings that will help with the identification of the info you are seeking. Even little things like how "Nitro" is written on the side of a barrel will help identify the proof house.

Some rifle chamberings can be difficult as only the bore size is given(not groove) and there can even be a couple of different ones for the same cartridge.

So pictures of all the markings are very helpful.

Thanks Erich
Sorry it took so long with the pictures and thank you very much for the help. No markings from maker (bought as a sauer)the safety system seems very odd, the side safety when on fire allows the shotgun bbl's to be used and to use the rifle barrel you must push the tang safety to fire (wich flips the rear sight up and the side safety must also be on fire. The cartridge trap is not like anything I have seen before. Lots of picts I hope they turn out and shed some light?

Thanks Chris

more picts

A few more

Sorry for so many.

The last for now (please ask for more if they would help)
The bore mics 362 363 at the muzzle and with the markings thinking it is a 9.3x72 but what bullet? The chamber cast looks like a straight taper?

Thanks Chris

From what I see it is a nice little drilling in 9.3x72Rx 16ga nitro proofed in Suhl.

The safety is a pretty standard Greener side safety and what looks to be a safety on the top tang is only a selector for the rifle barrel. With the selector forward the rear sight comes up and the forward trigger fires the rifle barrel and the rear trigger/left shotgun barrels is still available, sliding the barrel selector back makes the right shotgun barrel again available. Even the barrel selector on my hammer drilling(Zehla-Mahalis Guild gun) works the same only there is no side safety. My Post war Sauer is set up the same as your drilling.

What looks to be a safety on my hammer drilling is just a selector.


Standard S&B ammo should work just fine in your 9.3x72R. The S&B ammo has a stepped bullet to compensate the many types of rifling in the 9.3x72 bores. Mine has a bore diameter of .344 and a groove diameter of .364 which I think was originally built for lead bullets. Hawk(soft copper) and Buffalo Arms(stepped) have 200gr bullets appropriate for the 9.3x72R

Far right 9.3x72R S&B with stepped bullet.


2.5" 16ga shells are available from RST and Ballistic Products has components and data for handloading 2.5" 16ga. I took a 2.5" 16ga French sxs duck hunting with light #6 ITX loads and had a great time.

A JP Sauer should have what looks to be a Caveman holding a club for their logo usually on the exposed face of a locking lug. There are very many what are known as Guild Guns made by local gun makers that are not marked for manufacturer.

It's a common drilling design and a high grade example. I agree that it is a 65mm chambered 16ga (2 1/2") over a 9,3X72R. The gun appears to be in pretty decent condition. I wouldn't kick it out of bed.

I believe the gun is a Sauer, or at least built on a Sauer receiver.

Lots of "no name" German and Austrian (and some Belgian and French) makers sourced their actions and sometimes other major parts from Sauer.

Did I see an ELG someplace on the barrels? If so, they were made in Belgium, a common barrel source for small European makers (and even some high-end US double makers when they were still using "Damascus" barrels).

Neat scalloped boxlock action!!!

Thanks for the information, so what time frame would it have most likely been built? I was hoping to come up with some brass to try and get it running. 13 gr refers to the bullet weight? and BIG or BLG refers to a lead bullet? I am disapointed that it does not have a makers mark and am thinking about returning it. The safety may be hard for me to get used to I have many tang safety firearms. Any idea where I might come up with some brass?
Thanks Chris

Ammo available here for the going price.

Just my 2-cents �nobody mentioned the �set trigger� feature on the front trigger. Look at the JPG: MVC-020S.JPG When the drilling rifle is selected (rear rifle sight UP) the front trigger can then be forced forward (pressing forward on back of the front rigger) to lock it into �set trigger� mode. You can try the �set� feature (UNLOADED) without the rifle engaged and it will likely set-lock and trip for testing the trigger-pull, too. Adjusting the small screw, located on the back of the front trigger (reference the JPG above), will fine tune the �hair-trigger� tension; it eliminates flinch with NO TRIGGER CREEP. The rifle can also be fired normally without using the �set-trigger� feature, but the crispness of a set-trigger is nice if you have time to deliberately use it.

I own a SEMPERT & KRIEGHOFF, SUHL 16x16x8x57JRS [.323] SEMPER SUPRA Model. WWII military capture legally returned from Germany. It�s pretty nice and a reliable tack-driver, too.

Well I purchased a bag of 50 norma brass should have it toward the end of next week. Hoping to try a cast bullet first anyone have any recomondations? Any load data out there for this critter?
Thanks Chris

Buy some Hawk jacketed 200 gr .365 bullets and start with 39gr of IMR 30-31. I shoot 42-43gr with some old DKT 193 bullets and 40gr with the Hawk 200s. You need to play around a bit to get a regulating load. If you chrono the loads, be sure to stop at about 2,250 FPS to avoid high pressures the 9,3X72R brass wasn't designed for.

Apparently what I thought might be "ELG" is "BLG"!

Wondering what you guys think about running a gas check bullet through this critter? Also wondering about the use of a 360 bullet when the bore measures 362?

Thanks Chris

If you want to just plink there's a better way. Hornady #36500 95gr .365 diameter Makarov bullets over 15-16gr of Trail Boss is a lot of fun and cheap shooting.

I have not worked with this cartridge, but I have used slightly smaller than bore size bullets with black powder and gotten good accuracy. Since the x72 started with BP, it might be fun to try. My most recent project was in an 11.75x61R cape gun. The things I've found success with are plain base soft bullets (1 tin-20 lead), a milk carton wad on top of the powder, a pea of bullet lube (I used Lyman's old black colored lube) and compressed powder. I was able to get working groups at fifty yards with pretty coarse old sights.
Another option would be paper patched 357 diameter cast bullets. The 200 grain lyman might be a good starting point.

You need to slug your bore as there are many different configurations to the rifling in the 9.3x72. Some will run as small as .358 and work well with bullets for the 35 Rem. The rifling in mine has narrow but tall rifling having a .344 bore and a .360 groove diameter. I'll be trying some 348 Win. bullets patched to .364 and some .358 cast bullets with a 36 cal. greased wad under it.

that cartridge trap is different than my J P Sauer, I had to have the trigger ( fire pin) fixed on mine 16ga/22hp
