Have you reached the end of 8x57 and still want more?
8mm:
I worked up a 1.5" 3 shot group with 47 gr IMR4895 and a pulled Yugo 200
gr FMJ with one of my beat up 1903 Turkish Mausers.
The 1938 Turkish Mausers are like new and just as cheap [$40 wholesale].
8x57mm. 200 gr Yugo bullets, CCI 200, IMR4895, Collet neck, no crimp, RP
brass, and 3.160" I looked at different load books for IMR4895 powder
