I'm loading Lapua brass for my new CA Ridgeline 300 win mag. The brass is quite a bit heavier than my Win. or ABM brass.
After firing these cases I am also going to try to load "cooler powders.
First I'll be trying out;

Vihtavuori N165
IMR4831
H1000
Reloder 23

26" barrel
My case volume is 90.6
185gr Berger Hybrid target at 3.600 over all length ( .025" jump)

Thanks a lot.

RL22 was always my go to powder for the 300 Win Mag and a 180 gr bullet. 75.0 grs produced 3000 fps and sub MOA accuracy in three different rifles.

Yep, I've had two barrels that loved 75 to 75.5gr RL22 and 180gr bullets. Must be one of those 'universal loads'. Unfortunately I only have a few pounds left and I'm probably not going to find any time soon☹️.
I have enough of the other powders that I listed above to finish this barrel, so I will try to develop a load with those powders.
