1/10" twist will shoot everything from the 55g to 95g bullets perfectly into small groups from 100 to 700 (-MOA @ 700 so far)
That's what I had my 6x45 AR bbl in and now my Savage 24" bbl. VERY accurate to 700 yards...far as Iv'e shot ALL those loads.
***With the 95g Nosler HBT bullet I spit them at 2749 fps in front of H335 and that load will drop any antelope/deer out here to 400 yds w/ease. My col is 2.290" and yes the bullet is tucked into the brass by 2/3s of the length.
I do not use it past that on game & all antelope I have shot with it so far have been about 280 yards.
Now at the range at 700 yards it will print about 5.5" and splats the steel nicely, but its only about 1550 fps out there.***
This year I will be using the Barnes TTSX 80g bullet since it sure prints small groups to 400 yards and is a tad over 2800 fps.
My coyote load is the 65g vmax at 3053 fps and that just plants them on the spot. I have dropped 5 at just a tad over 600 yards with that load and DRT last year and 103 went down to it total.
