The bench is for load development, after that it's just a crutch that imbibes false confidence.
My favorite practice drill is called a Run Down there are many variations, but the idea is to practice different positions with an elevated heart rate.
Hard to do at a public range, but it's very educational if a suitable location can be found.
There are a few different variations, my preferred method is to setup 4 targets and mark out 400yd in 100yd increments.
The drill begins prone at 400 when the stopwatch starts, firing 2 rounds at the first target.
Proceed purposefully to 300yd, assume a sitting position and fire 2 shots at the second target
Proceed to 200 and fire 2 more from kneeling,l at the third target
Then head to 100 and shoot 2 offhand at the last target.
Stop Stopwatch, and proceed to evaluate targets. Time isn't really important unless you want to turn it into a competition
Knowing when NOT to shoot goes hand in hand with shooting ability, and this requires being humble and being honest with ourselves.
The 'run down' gets the heart going and taught me VOLUMES about heartrate management.
When it comes to shot placement I can speak from experience and say that I made a few poor shots starting out. I have poked guts and had to clean stomach contents and bile off the meat. I have obliterated most of both backstaps (mid spine). This was all part of learning for me, and if I encourage those I mentor to KEEP IT SIMPLE until they have gutted a few animals.
Wait for a (near) broadside presentation. Aim for the far leg, crosshairs 1/3 to 1/2 way up the body. Avoid extreme quartering angles starting out.
Getting HANDS ON with the internals gave me an intimate knowledge of the anatomy. It took a few though.
Keep shots below the blue line indicating the spinal cord - it dips lower than many hunters realize.

Cup and cores at MODERATE VELOCITY have been killing for over a hundred years, and do so effectively. 150gr-165gr in the .308 have worked great for me. With a good double lung shot, 'Time to Tip' is typically 8-10seconds.
Monos help cut down on meat damage but at lower velocity, wound channels can be small for my liking. This can result in delayed killing.
I like Copper bullets, but it's been my experience that they benefit from being pushed fast to create similar wound channels to CnC. The 308win can do this if one steps down to a 125gr bullet
