Ok I visited the accurate mold site and found a "stop ring" bullet #32-182L
also I went to Buffalo Arms but couldn't find their stop ring bullet that is supposed to be in stock. Anyone familiar with the 32-182L accurate bullet? Still haven't measured my bore but plan to tomorrow. Hope my brass gets here in a day or two.

As best I can measure my barrel is .312/.313. Didn't check twist. So any good bullet of 170 or 180 grains would work?

I use the 32-182L for my Aydt. It works really well. My bore is 0.307” and grooves are .317”. I specified to have my rear bands be 0.320” and front band and nose at 0.307”. The stop ring is 0.330”. Bullet casts well (25 to 1) and drops in nicely to a fired case - no resizing necessary. The grease holds it in place well enough to load. 

If I were to order another one, I’d actually make the nose and front band a tad bit larger. Given how narrow the lands are I could probably just it engrave a little (without much resistance) and help with bullet alignment. In any case the limiter for me is myself not the bullet or the rifle.

I have a couple of 8.15s, one of them a Haenel Aydt circa 1908.  Don't shoot jacketed bullets.  The barrels were not designed for them.  As mentioned earlier, the Aydt is big, but it is no stronger than a Stevens 44.  It is only made for punching holes in paper with lead bullets.  Light loads of powder similar to 4227.

Slug your barrel.  Measure both land & groove diameters.  Get some sort of cast of your throat and measure that carefully.  Dimensions were not standardized.

These rifles were designed for stop-ring bullets, but with the proper sized flat based ordinary American lead bullet, you can probably get better accuracy than with any stop-ring bullet if you breech seat the bullet ahead of the throat.  A plugged case does well for seating bullets in an Aydt.   

The original sights work OK, if you even have them, and if you have good eyesight. Otherwise they are frustrating.  Steve Earle sells an adapter that slides onto the "dovetail" surface of the upper barrel flat.  You screw scope blocks onto that and then mount a decent target scope.

That had to be a bummer. All that hot nasty work and no fun...

The basic throat angle (CIP) is .955°, per side. It can very some what from gunsmith to gunsmith but, will be pretty close.

The throat, pretty much starts at the end of the case @ ~.348

This is what I do, for both breech seat and SR:

I run a 30/30 threw a 32/40 die. Trim it to ~1.94, then fire form it, with 10gr Unique, with COW or corn meal, to the mouth and use bullet lube to keep it in place.

I measure the case mouth ID and then, trim it back to either the groove size, for BSing or, the diameter of the base of the SR bullet so, that it a nice push fit, into the case.

From there, I try it, in the chamber and if I can close the breech block, pushing the case a little forward, I try it at the range. 

That way, the bullet is aligned as well as it can be in the case and throat.

This is my best OH target, shot in 2016 at Spokane in the German rifle match, loaded that way. I'm not a good OH shooter!

All my 8.15x46R rifles (with the exception of my 2 Wehrmannsgewehre which use a .323 stop ring bullet) use either the .316 or .320 BACO stop ring bullets. Usually you have to call them to have one made. 

With 12-14 grains of 4227.
