looking for input and experiences with shooting 200+ grain pills out of the 300 win mag. What powder has given you the lowest es and sd numbers?
H1000 would be a good starting point for 200+ gr. bullets. Good luck
i have shot a variety of bullets, but no pills so i cannot help
I also picked H-1000 for 210s and 215s. It's not too temp sensitive, being one of the Extreme powders from Hodgdon, usually gives very good velocity and is available.
45, I use H1000 in four Weatherby calibers. With the summer temps here in Az at 100+ and some hunts in the high country below freezing this Extreme powder has great consistency. The newer IMR Enduron 7977 is a very close match as well as being temp insensitive. H1000 works for me, but every action/barrel is different and sometimes another powder may be the trick.
H1000 has always been my go to powder. I've found it very temp stable, and accurate.
