I need to make some different dies for sizing, but this is what my 41-240 sizer did to the 93.x66 Sako brass.
Length ended up at 2.590" after being blown out with COW.
Looks like a 405 size die will do the job just fine.
Might be able to use a 405 Reamer, if the base is around .453 diameter....and add the belt clearance.
Any way this case with a .450 base holds 77.5 grains of water.
Even with the small base, looks like the same capacity as the 405 Winchester.
So load data is available to start with.
Some Ruger data is also out there.
Base diameter of the brass is .473" not the standard .465" of 06 brass.....better for belting.
