60g Nosler partition shoots 1 1/2" in a 14 twist, and they do better in a 9 or 12 twist. They really make a mess out of a deer out of a 22/250 with a 14 twist and max load of IMR 4350, win primer. These will often surprise you in how accurate they are out of a 12 twist or tighter.
I shot them out of a 12 twist Savage 12, 22-250, 34 grains of IMR-4064, kissing the lands.
3/4-1" best I remember with 3/4" being the norm. Shot quite a few deer with those including my largest bodied whitetail, somewhere in the 250+# range.
Extremely short blood trails. In fact only ever had to track 1 deer, most died within 15-25 yards while quite a few were DRT.
All deer shot were under 100 yards so velocities were still high which I feel made a difference.
