You still have go the step to fire form it, and the factory 375 H&H doesn't print the same as the Wby loads.
Still...all-in-all, I love the round.
Not quite the same but I have had 358 STA which as you probably know is based on 375 blown out. I was able to work up loads I used in the unfireformed brass where I had point of impact in line. From memory I used 200 grain Hornadies and a backed off load of Varget Maybe 75 grains) in the unformed brass. That load would also shoot to the same group when used in formed brass. But I use a lot of reduced loads so it fitted in real well.
