We did find the wound channels with the 7mm-08/140 ABs to be more substantial, and penetration was also very good. With 100+ fps higher muzzle velocity and a little bigger bullet, those result seemed pretty reasonable. 6.5 was with 129 ABLRs and 130 ABs and usually found those under offside hide, where 7mm-08 w/140 ABs usually left a nickel to quarter sized exit. It's not going to make the difference between a dead or live elk, but I do have a more confidence in the 7mm-08 on elk based on our experience.
