My brother bought a nice drilling from Cabelas that was supposedly a 16x16x9.3 72R.

Purchased some 9.3x72R and they would only load about halfway in the chamber. Made a chamber cast with cerrasafe. Appears to be a 72R case tapered down to a bore diameter of .318!

The 8x72R uses .323 bullets. Anyone with info on this would be appreciated. Thankyou in advance.

You'll also probably find that it won't take 2 3/4" shottie shells either. It should be a 2 9/16" shell.

Can you post a photo of the proof marks on the barrels?
The 8X57JR is .318.

If your brother is not happy with the gun I would return it.
Being it was sold as a 9.3x74R and it is something else,I would think they would give a refund.
I returned my Sabatti no problem, it had over size out of round chambers. Barrels crossed 1" at 50 yards, with Hornady ammo.

It was sold as a 16g with 2 1/2 chambers. Found out from Huntington dies that its a 8x65R (.318). Brother is happy with it but just wants to shoot it.

A good place to get the shotgun ammo...



Get the biggest shot size, BTW. Their #6 is about like our #7 size, I find.

Also, you can use 32 Special bullets to re-load it. The bores were all from .319 to .322. Even at .318 the .321 32 Specials are fine. We used them for many years for our 8X57JR drillings, before "J" bore bullets were available. I find them more accurate on a whole, also.

I like the Remington CorLokt best.

220gr Hawk Bullets work great, too.

more likely 2 & 1/2

More like 65mm

Sounds like a nice piece. Once you get the ammo sorted, I'm sure he'll love using it.

Your brother should be ecstatic to have a drilling with a rifle caliber like the robust 8X65R instead of the anemic 9.3X72R. The 8X65R is a sort of rimmed 8mm-'06, and outperforms the 8X57JRS about 300 fps. across the board. I had my Krieghoff drilling rebored to 8X75RS from 7X65R for that reason.
