Large bore 8.15 X 46R?

The Scheutzen rifle I ordered arrived today. All evidence points to it being a C.G. Haenel as it is so stamped on the barrel and the receiver is stamped "Original Haenel-Aydt". Proofed in September of 1926. I didn't expect it to be quite as heavy as it is, 11.5 lb. The sight is near perfect as is the bore. Trigger is literally set to a "hair". I cast the chamber and it is definitely an 8.15 X 46R. However.....I expected a groove diameter of somewhere between .315 and .320 but it mics .345. The neck of the cast mics .380.

As is my normal practice I cast the chamber a couple inches long to pick up the bore/groove dia. and when I measured the groove I was a bit surprised. So, I slugged the bore also. Same thing, .345. It's no big thing except that I don't have a 34 cal. mold. Accurate Molds makes a 170 gr. mold at .340 and I'm certain Tom will open it up to .347-.348 so I'm not helpless. I do need to check the twist before I order a mold.

Have any of you guys who fool with the Scheutzen rifles ran into a groove dia. that big for an 8.15?

Edit: The twist is 1 - 20 1/4. That seemed slow to me so I checked it twice and it is. That's gonna take a shorter bullet than 170 gr. I believe, no?

Sharps,

I can't help with answers about the bore but I would sure like to see some nice pictures of it!

Thanks, Diz

Apparently you got a rifle rebored and rerifled to 8.5x46R aka F(rohn)46 ½ x 8,5 aka 8.6x47R, a very rare cartridge once designed for "freshing out" shot out or, more often, rusted away 8.15x46R barrels. Introduced about 1900, it had disappeared by the early 1920s again. Anderhub+Kellner +Techel have two pages on this cartridge in their book "8.15x46R – Die Deutsche Schützenpatrone". Sorry, no load data. You got an email.

Well...I didn't check the chamber cast as closely as I should have. I didn't bother to check the length at all, just the head and neck. It appears to be a straight taper case of about 2.07 As the Haenel doesn't have a recessed rim a cast won't pick up the rim. I'm adding the .060 of the 30-30 rim.

Thanks Axel, I'll check. I thought freshing out the bore might be a possibility but now I don't know. 'Course I didn't know before...

Pics forthcoming!
