I have a good friend that swears by the SST in his centerfires.
I had a few conundrums with them, but found the FTX stellar, so I think perhaps my " problems" were more my fault than the bullet.
I have harvested elk with hot cors in the 8 x 57. It was my first rifle, and yet one of my most accurate. It is a pre war post office issued nazi Mauser model 98.
I will look up the load when I get outside.
