I'd go with a slower twist, shoot 55-60 grain bullets max at respectable velocity's and go kill stuff. If you want to shoot heavier bullets, get a larger caliber rifle

How about you look at the trajectory of say a 50vmax @3500 and a 75amax @3050 out to say 800 yds. You will find that it is the 50 that drops like a rock, and look at the windage while your at it.
I actually ran these numbers last night, but didn’t want you to feel like I was being argumentative.
53 vmax at 3440 (really smokin) and a 75 a max at 2970 (my old number).
The windage difference at 400 yards (which is what I’ve always considered max practical range of any “calling” rifle) was less than the length of my index finger, which is hardly worth worrying about as you’d have to calculate either one to get a hit on a p-dog sized target. Beyond 400, of course the 75 will really shine, but I can’t see where that’s the slightest bit significant in a calling rifle. If I was shooting those cute little prairie dogs, I’d want a 6mm anyway, assuming fewer crawling back into the hole at long range.
Is the 75 better in the wind, of course it is, but it doesn’t matter again as you’re looking at enough windage either way that you’re going to need more than Kentucky to make a hit.
