I have some that I bought for a WY. Antelope/Mule Deer hunt, but I tested the 140 Accubond first and shot a .187" (3 shot) group right off & sub 1/2" groups after that with a sporter wt. M700ADL, so I have parked the BT's for now. Besides, the Accubond has a better BC than the BT in this bullet, noteworthy because in most calibers & bullet weights the BC of the Acc. & BT is the same, but this Accubond is a good bit longer. And it expands well & penetrate comparable to the Partition, a combo too tempting to turn down fore me. I have used this bullet for Whitetails, Mule Deer & Antelope from 8 yds. to 410 yards with great results.
