Any recommended loads for the 8.15x46r?  Thanks.

CBAshooter, 12.5 to 14 gr of 4227 is what I have used in mine.  In general you can use data for 32-40, staying at the lower end.

Regards,
Joe

I've used those 4227 loads as well but when I came across this 2400 load I just stopped.
My chamber is really weird  .for one a shell must have got stuck because in the neck area it's completely galled like from.a drill bit but they extract fine.
My chamber length is exactly 46 mm off the edge of the case (inside of a neck ) it is a .349 dia neck after firing.
The throat starts at .323 from case end at  45 degree angle until it reaches .320 ,then tapers at about one degree until it hits the groove diameter of .318 
My buddies chamber just keeps going from the outside 
of the case until it reaches rifling.his takes a stop ring fine.i think that's the typical chamber.

oughtsix-
is this breech seated? 
I'll try wc820 I have 24# and haven't used it in awhile.

Exactly what Yamoon said! I have three rifles in this calibre and the same stop ring bullet. All like 13.5grn of 4227.

I also use the same stop ring 165gr bullet, but with 12grs of 4227. I think I use 13grs in my Wehrmannsgewehr.

In 1983 or 84 when I first started getting into casting for rifles in bought a system AYDT  in 8.15x46R. At that time custom molds and dies were just not as available as they are now so my gunsmith talked me into punching it out to 32 Winchester special. it shot wonderful with a bullet from my pope mold. I sold it to buy another gun a couple years later. It's sad  that I got talked into ruining it like that.
back then you had to talk to old guys or have good books.
Back then you couldn't just get in the internet and find misinformation on a subject 

If I would have had the information I would have known how easy it would have been to make cases had left  the chamber as it was.

I have two 8.16x46R rifles with wildly different chambers and barrels.  Both work with stop ring bullets.  But the Martini has a .308 bore and .314 groove.  If I breech seat 311403, it shoots very well.  I have yet to find a good tapered bullet for the original Haenel Aydt with its .316 groove diameter, so I continue with stop ring bullets.

Think about all the steps we take to make our breech-seated bullets shoot accurately.  I subscribe to the shoot-as-cast school.  Why cast good bullets if you are going to distort them when you push them through a sizing die?  Cast them, pan lube, and breech-seat carefully.

Then look at a stop ring bullet.  A too-small base with a fat ring, maybe .335 diameter IIRC, and a tapered chamber that winds up at groove diameter. When the rifle is fired, the bullet is pushed through that tapered throat.  The displaced lead has to go somewhere, so it gets squeezed back over the too-small base, leaving you with an irregular base.  I am mystified as to why those rifles shoot as well as they do with stop ring bullets.
