I have spent two days looking for safe min and max load data for my 300 wby shooting 220 nosler partitions using RL 25. The nosler book only has 19 and 22. I'm moving on to my third type of powder with this gun and load. I've tried H4350, IMR 4350 and H4831sc with my best results being 1.5" at 100 yds. Looking to improve on this with the RL 25. Thanks in advance for your responses as I know there are many knowledgable handloaders on this site. Thanks Kodiak Rain for getting me hooked on this great hobby of handloading.
