300 WM Semi-Auto

I am about to start loading for my Nemo Watchman 2.0 chambered in 300 Win Mag. Does anyone have any experience with this platform and what powders would be optimal for accuracy?

I would try h1000 and h4831 same as in a bolt gun. reloader 22 has also shown me very good accuracy also.

I use IMR 4350 In my Win Mag pushing a 210gr projectile.

I ordered some Vihtavuori N165. After speaking with one of their reps he thought I would need a slower burning powder in a semi auto. I am interested in the H1000 and have heard that is a good powder for accuracy. Thanks for your input. I’ll keep the thread posted when I get them loaded up.
