The ablr is a pretty soft bullet. Fast expansion, moderate penetration. I have been shooting Accubond in my 30-06 for a while. It does a good job killing them, but much like your experience. There is not much exit and very little blood. Most of the deer I shot no trailing needed. But still sometimes, they are going to run, and when they do I want to be able to find it. If you want a big hole out the back go to something a bit harder. In my 30-06 I changed from 165 Accubond to 180 Fusion this year. last deer I shot looked like a seen from a horror movie. Blood everywhere. I am happy with this change so far.
Check velocity on a chrono. That is the only way to know what you are getting. That is a really short barrel especially for small bore like a 6.5. Might need to enlist the help from a handloading friend to see if you can get the velocities up.
If you want them to go down fast. Shoot more towards shoulder. That is a safe shot, but they are usually going to run a bit hit back like that.
