I believe that the 9.3J is barking up the right tree considering the bullets that are available. Bullets for the. 375 either tend to be too soft (375 win levels), or too tough (made for the H&H). 9.3J performance splits the difference between 9.3x57mm, and 9.3x62, except fit a short action and semi A platforms thus bullets are already taylor made. The 286gr PPU projectiles are soft enough to expand on deer at x57 levels yet hold together in tougher assignments. Bullets in this diameter tend to be readily available. Not many in NA use this diameter yet most of the major manufacturers are producing components and I've seen they're the ones in stock. Go figure
Smart man recognizing the bullet construction dilemma...
As well as availability...
Had lots of poor performance with 270 grain bullets with the .375 Raptor. Zero expansion.
...and the Sierra 2900s (200s) were more of a .375 SOCOM bullet They work in the Raptor but not ideal... also kinda scarce to find reliability.
I am hopeful of the Lapua G574s in .366 (have 1k on hand to play with)
