Berger also makes a 168 classic, I have some but haven’t killed anything with them. Remember your idea of drt is also very subject to shot placement. I’ve seen a 220 swift kill an elk before it hit the ground numerous times. Neck shots and high shoulder will make any bullet look awesome. One of the best “death switch” guns I’ve ever seen was a 25-06 with an accubond. Pretty much a 3300 FPS grenade.
