My rifle loves 140gr but the S&B wasn’t great (at least not for me). At 200 I get good groups with federal 140gr soft points, but farther than that the groups start to open up (some of that may be me, some may be projectile design). I’ve liked the hornady ELD bullets (143gr?) out to 500 (note, I didn’t shoot paper at 500, but I hit a 6” steel every time but one 19/20 — that’s just a hair over 1MOA, so that’s pretty decent).
Old pic, 200y. 10 shots - that’s a little over 1/2MOA. That was the best of 3 targets, but the other two weren’t a lot bigger. I’m almost certain that was federal 140gr SP. as I think I said earlier, it was not as accurate at 400 or 500 yards, in my experience.
I have a 100y target with that ammo somewhere…
I also got some relatively inexpensive Norma 140gr that seems to shoot well - I haven’t tried anything serious with it, just a quick zero before hunting, but my son shot a deer at about 200 (I think it was lasered at 207?) and hit it exactly where he was aiming.
