Righto curiosity got the better of me last night and I slapped 5 cartridges together to do a quick test on the way home from work.
Obviously 6 PPC data was a safe starting point, I did have some Re10x on hand which would rocket along but the safe option was 8208. I've been loading a compressed loads of 8208 in my Grendel for years so I had little hesitation with 32gr and giving it a light crush.
Hornady 6mm ARC brass, 1.49in, Rem 7.5, 8208, Nosler 55gr BT, COAL 2.130
Charge Velocity
32.0 3494 3493 3469 3493 3494
5 shot group went 0.7 MOA which I wasnt expecting. This is a start load but Id be surprised if I could fit another 2 grains of 8208 in the case, I reckon with the right powder 3700fps would be achievable.......
