I used 100 gr Nosler BT's for a long time out of a .25-06 Rem on deer with great results in the "dead deer" column. But what I found was numerous core jacket seperations. I would find a hole in and a hole out but recover the jacket inside the animal at various ranges out to 320 yards. Dead is dead but I never really liked the idea of my projectile breaking up. I loaded a Model 7 Youth for my son in .243 with 85gr Partitions, set him up in stands where shots were 150yds max. As the many videos I shot of him proved the Partitions were devastating at that range in that caliber on deer. I never liked my longer range accuracy out of the .25 with Partitions, groups would get a little loose past 275 yds no matter what I tried so I stuck with the BT's (maybe just that rifle?). Then the Accubond arrived. It is advertised as a 60%-70% retention bullet, just like the BT (I know better when it comes to the BT). Anyway, what I've found since using the Accubond is exactly what Nosler says, I've recovered 2 bullets from deer, the first weighed 69.7 grains from a neck shot @ 130yds, and the second weighed 71.4 grains from a shoulder/lung shot @ 322 yds, both mushroomed nicely. IMO, the Accubond is the compromise I've been after, in flight it's an accurate Ferrari like the BT, upon entry it's a Peterbilt like the Partition. One vote for the 110 gr Accubond in .25 cal, Nosler got it right, again.
