Hoyt with your 375 and the 35 where abouts is your OAL coming in at roughly?
If your barrel has the the throat for it can you load the heavy’s out to 3.2ish OAL to take advantage of a long action? I know the wsm dosent suffer the short neck syndrome of a 300wm but iirc it’s not an overly long neck like the 30-06.
A small .375 might be a real good use for the several hundred 7wsm cases I’ve had sitting in the corner for years.
So... I gave it a whirl... longest OAL for this .375 WSM with the #3000 is 3.180"...

I wouldn't go much longer than that due for bullet engagement anyway...

I will not be changing from my 3.050" load that was so consistently accurate. If you really wanted to maximize the OAL, you could easily lengthen the throat... for me with this rifle, I was going for a solid hunter with 400-500 yard capability carrying a good payload... so looking for more than the two loads that I currently have is unnecessary. The rifle feeds perfectly, and the Alaska Arms Coffin Magplate gives me four rounds down.
