I don't use the Wolf stuff or anything with steel cases.
I have an AR with a 1/9 twist. I regularly shoot 68 grain bullets through (very accurate). That's from a 16" barrel. I also regularly shoot 40 grain bullets through that AR (very accurate).
I'm not positive that's what you're asking so I'll add this...
you can shoot heavier bullets through your 1/9 - they just won't stabilize past a certain distance (if they stabilize at all) - so try what you want and test at different distances to see what you get.
I have few rifles with 1/7 twist, so I also load/buy some heavier stuff (75gr, 77gr). I have tested them in my 1/9 twist. I loose a little accuracy, but they would be effective out to 200 yards.
I've seen 1/9 twists that don't stabilize anything heavier than 62gr, so the true answer is that you'll have to test a little. Common answer is that the 1/9 will usually work well up to 69gr.
I wouldn't buy a bunch of any ammo over 62gr until you do some good testing yourself.
