    Also starting next week will be working on the 180gr TSX at 3200fps plus and see if I can get tight groups at 3200 plus without going over max. H4831 and IMR7828 in 300WBY shot fast and great for two friends of mine and I will try and get there with my rifle.

    Not bad for a heavy weight. can't wait to also work with the TSX should be fine accuracy and ballistic.

    That's a mean looking round! Good accuracy as well.

    I'm gonna start reloading a bunch of different bullets as I wait for my gunsmith to finish my custom 300 RUM. I'm a little curious at what velocity to expect when I load a stiff charge behind the Barnes 168-grain TSX bullet.

    Yes, I will be testing the 180gr TSX with a stiff charge this coming week and I am curious what velocities I can get plus accuracy.
