I'm working up a new load for my custom .300 weatherby, I'm Planning in working with the 152 Hammer Hunter...

Anyone got some recommended Starting powders?

I suggest imr4350. Always been a great powder for the 300 roy. Now we have some new good powders but the best I have ever done with a 180 is 3240 with old 4831. So how much have we progressed? But with 150 and 165,s 4350 is better.
