Would like the 7.62x51. I have 308 and I did the pressure factor figures and it looks like the starting load for the 308 is higher than the pressure "50,000 psi. for the 2A1.
I have been shooting the managed recoil loads and get 5 or 6 firings from it neck sizing before having to full length resize. :---
I started with IMR 4895 and was loading 39 to 42 grs. with 150 gr.sp.
Used almost all that powder up.
I now have 1 lb of H-VARGET , one lb of H 4895 and one of IMR 4350.
I have loaded 40 rds with 44 gr H-Varget so far.
These are the other cals I am loading.
303, 7.62x54, and 8x57. :---
