doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com What caliber is 11.15x65?

Re kcordell's post above, if I'm remembering correctly the chamber in that drilling was necked and had the typical (.43) Mauser base and rim dimensions of 13mm/15mm respectively.

We haven't gotten word from Silver on his prospective drilling as to whether the chamber is necked or what the base dimensions are, but most of this thread has been leaning toward the other and probably more common 11,15x65R "LK" that has a straight case with base and rim of 11,9mm/13mm respectively.

Dang Germans - too many similar cartridges!

Steve,

Thanks for your help there earlier!! :-)

Steve,

When I saw that LK on the CH4D website I wasn't sure what cartridge it referred to. So it was the straight walled case. Where there many variations?

All, this seems to come up periodically so hopefully Dave will save it somewhere.

The brass can be made from 40-90 Sharps basic brass or from 30R Blaser brass. The head diameter is NOT the same as 9.3x74R. That said, you can use "thumper" brass if you are careful and aware of the 11.9 vs 12.1 mm head measurement difference and keep pressures low. A gunsmith friend shared his load with me which calls for 300 grain Hornady XTP pistol bullets. They work nicely in the "Baby 45-70" on all but elk or larger-sized animals. For those I use the 300 gr Swift A-frame pistol bullet. One of these loaded full-blower shot completely through 16 inches of wet phone books and half-way through a 50 lb bag of cracked corn and was found perfectly mushroomed. The 38 caliber XTP's are also very nice in the little 9.3 and much easier to get good groups from than lead; yet they are all soft enough for Henry-type rifling and still give good expansion. If you are leery about using this cartridge on game, consider that 11.15x65 ballistics outclass the .454 Casull by a good bit.

Pete, like many old BP German cartridges, the brass starts short (40mm) and goes on up to the full LK (LanKaster meaning shotgun in Duetche) 65mm Express. I think Dixon shows 5 or 6 variations. It was factory loaded by Utendoerffer, DWM and finally GECO up until WW2.

Good shooting,

C.

The gun sold for $835 or so.
Too many new/unknown things for me to bid on it although I liked the engraving and the side lever setting.
Thank you all for your help.

You didn't miss anything except shooting cheap .410 shells in a neat rifle. You're right, too many issues.

Here it is seven years down the road and, yesterday, I finally got the hard cast bullet out of the bore of my 11.15X65 Sauer. My next step will be to find a soft, store bought bullet to shoot. My wish is to be inventive and shoot those bullets out of plastic .410 shotgun cases sealed with wax or glue. What could be simpler? I do have a few 11.15X65 cartridges, a gift from a friend, but I would rather not use them for shooting. I will try to check back in less than seven years this time.

Eightbore, explore UK's .410 board http://www.fourten.org.uk/ a number of members there have set up .410's with rifled slugs and such. You might find exactly the information you're looking for.

Steve

Thanks.

Another question that has come up is "How do .410 shotshells pattern in heavily rifled bores?". I plan to answer that question also. I have shot my 11.15X65 drilling barrel with .410 skeet loads at skeet targets with good results, but a good 21 yard pattern would be interesting to inspect.
