Yeah, you can get more speed out of the 75 but it never was accurate enough for me at those higher speeds.... YMMV as it does with a lot of opinions here.
That's been one of my questions. I'll find out soon.
I don't have any desire to run heavy bullets slow; if that's what they take I'll stick with my proven loads with 65 and 69 gr Sierras moving fast.
I couldn't get the 77gr Nosler to shoot well in this barrel at all; 2"-3" groups @ 100 no matter what.
