Huntr, thanks for satisfying my curiosity. I am always interested in learning more about the use of monolithic bullets in the 7x57.
Your 50gr H4350 load works well with cup and core 139-140gr bullets in 2 out of 3 7x57s I have. In fact one rifle handles the load with a 154gr Hornady InterLock.

I recently picked up some Barnes 120 and 140 gr. TSX bullets for my 7x57. i notice in the latest barnes manual that W760 give some of the highest velocity with those bullets. That's probably the powder I'll start with when I do the load work up. I've gotten my best results regarding speed and accuracy with that powder in my three 7x57s.
