This is a bullet you can load to some variation and it will still perform.
When I began using a .375 in the 70's the limited data compared to today had 88gn of (IMR)4350 as the top load. This was heavily compressed to the point that sometimes it bulged cases in the shoulder are and even allowed the bullet to move forward because there was no cannelure on the 235gn Speer.
These days I have topped out with 80gn of Rel 15 for 2852fps, 87gn of H 4350 for 2949fps, 80gn of Rel 19 for 2262fps (Very unimpressive velocity), or 79gn of Varget for 2982fps,
