I've been shooting 165gr Ballistic Tips, through my 300 WM, for about 16 yrs now. I've recently been considering taking it out west for a mule deer/elk hunt, where a little more penetration from a 165 would be great. I don't want to switch from a 165 to a 180, because I am shooting consistent .375" or better groups at 100 yds, and I simply don't want to touch anything. My question is, has anyone done any side by side comparisons on Accubonds vs Ballistic Tips, as far as accuracy, and point of impact? I know both the 165 AB, and the 165 BT, both have the same B.C, and S.D, basically the only difference, is the OAL of the AB is 0.018" longer. In theory, they should shoot almost identical.
