Thanks Dr. Mike; this is for my #1 using +p cases. It should be just fine. Thanks again.

I would sure like to work up some loads for my "Bob" with Reloder 16 and 17 but I just don't have enough powder.

I found a can in the back of my cabinet. Hopefully there will be more available sooner than later.

Good luck with that...
From my experience R17 is at home in the shorter fat type cases and definitely my wsm/wssm favorite powder.
Like it was almost made for the WSM and WSSM's where it runs those velocities right up there equaling and at times surpassing their counterparts like the 25-06 vs 25wssm and the 300 wsm vs 300 win mag
I hope it works great for you!!

Keep us posted how Rl 17 works for you, it’s been fantastic in our 7-08’s. It really delivers on accuracy and velocity.

I forgot my chronograph so velocity will have to wait; I only had 10 bullets to try; so far I am encouraged. 2.921 is a pretty good looking 3shot group. 2.928 as well. I know I pulled that shot high and left at 2.908.
