Hello

Anyone ever see a Chapius sidelock double in 9.3 x 72R?
Found a 2 barrel set. 20ga and 9.3.
Was it originally a shotgun and then they had Chapius add the 9.3?
Both barrels marked Chapius on the rib.

Any input?

9.3x72? That hasn't been a popular caliber for many years....the gun must be quite old? Perhaps you meant 9.3x74?

or even a 9.3x74

Even better!

I am going on memory and mine is crap lately.
I think it was 72 but could have been 74.

I will try check on Sat.

There is, or was, a 9.3x72 as well, but it was quite some time ago and of limited power compared to the current 9.3x74R caliber. It started as a Black Powder round, and has about the power of a 30-30 or 35 Remington; a 193gr bullet at 1,952 fps.

Unlikely it was a 72; no reason to make a 72 on such a strong action when the 74 is so much better.
And it is also likely that both barrels were made at the same time; doesn't matter anyway; they are both factory. I saw such a set at the Owatonna Cabelas once.

I agree with dpcd!

I don’t know how long Chapuis has been making double rifles, but if that double has barrels chambered for 9.3X72 the rifle must have been made around 1910 or earlier.

The 9.3X72 is marginal even for deer at more than 50 yds! I would guess this rifle is a 9.3X74R rather than the 72! The 74 is a far more powerful round, just shy of the 375H&H flanged magnum. The 72 is about the same power as a .38 special plus-P handgun round.

The 9.3x72R killed a LOT of game in past generations. Strictly a short range caliber, from a stand in the forest it killed quite well without a lot of meat damage. The 35 Rem is a good comparison and I don't think anyone would think twice about pulling the trigger on deer with a 35 Rem. In either case, these calibers are getting close to modern day shotgun slug performance.

I have owned and shot game with several 9.3x72r's over the years. It's effective on game
up to elk at short range and a great whitetail cartridge. I currently have a JP Sauer drilling in 12x12x9.3/72R. Very underrated. Very popular in Germany for 100 years.

No one is saying the old 72 is a bad cartridge; just no reason to build a new one when we have the 74.

Hope it is a 9,3x74R.


I have that combination ... 9,3x74R and 20 gauge barrel set. Both are marked on the underside w the same serial number as the frame.

Mine is a box lock not a side lock.

Is a GREAT pair and wonderful hunting tool. The 20 ga bbls have truly huge reach for a shotgun.


I do better with it in the field than with a 12 gauge Citori.

Mike, yes, that's typical of a European shotgun. I think a 4-choke set-up for a European gun would be:

Full
Extra Full
Ridiculously Full
Almost Closed

:-)

Have not made it back to the shop yet.
