Best Powder to use for Christensen Arms Ridgeline .300 WM

[Jbell9011]

I recently purchased a CA Ridgeline in .300WM and wanted to know what suggestions are out there for bullets and powders. I currently use 180gr. Nosler Partitions with IMR 4831 powder for all of my big game hunting. I just wanted to see if you all would suggest a different powder to use. I'm not looking at shooting any further than 300-400 yards for now. I've been using the IMR 4831 for years on a Remington 700 .300WM but wanted to see if there are recommendations for faster or slower burning powders for this particular rifle.

Thanks

Been reloading the 300WM for 20 years with various powders, and different bullet weights in the 180 to 200 grain range. I have used H1000 for the last couple years and have good accuracy and increased velocity with no pressure signs. I would recommend H1000.

Reloader 22 and IMR 4350 are my favorites. I have used H1000, H4831SC and had good results but the best accuracy and speed seems to be in the RL22 and IMR4350.

Powder will be the H1000

I’ve only been playing with RL22 and 180 accubonds. Here is a pic of the first node we found during the work up. The flier at 11 o’clock was the first shot after a fresh clean and oiled barrel. That’s at 200 yards.
