Nor did I , that is why I wrote "regulate" rather than "shoot"

I was not suggesting either to the poster, or to "New Guy" the Heym chap, that there was anything amiss with his gun. Simply that a double without information as to the correct load for which the rifle was regulated is as much use as tits on a fish. I imagine that "new guy" supplied the required info in a few minutes.

DR's are not designed for handloaders, they are built for one load and that load alone.
The fact that with a lot of messing around they can sometimes be made to shoot with another formula is irrelevant and should only be necessary with rifles for which the original load is unavailible.

If one knows in advance of ordering a rifle that factory loads are going to be unacceptably expensive and some other concoction of propiatory head and powder and primer is going to be used, then it would be best to supply these to the gunmaker and regulate the rifle for the "homeload" in the first place and save a lot of tears.
