my 4 - 257 Weatherby`s like these 2 powders best for speed and accuracy RL. 25 and RL.22 .
I thought I liked R22. Never tried R25. I was at the range on a hot afternoon (about 85 - 90 degrees) and experienced a heavy bolt lift with a well proven and safe load. Never shot in that kind of heat before that day. Packed up the .257 after that.
H1000 for both of my .257's and never had another problem.
