Tried out my Mauser I made up from my old Turk today and found it still likes the 21.5 grain SR4759 load with the Lee 175 grainer and also reached a "sweet spot" with 32 grains of H-4895. 31 grains wan't bad either but 34 grains and the groups started spreading. Guess I will have to try 33 grains.
I had a shoulder separation on one of the non-annealed LC 68 (sized from 30-06). None of the annealed cases even cracked or neck split in the least. This separation occurred with the 21.5 grain load of SR 4759. These are also ones that I had pushed the shoulder back another .005" to get them to chamber in my 24/47. I wouldn't think that .005" would make that much difference. The headspace on the Turk is fine. Maybe it just is the brittleness alone from all the working of that brass without annealing first. I am definitely going to anneal first from now on.
