Just my 2 cents....
Log your shots in a shooting diary as well as video tape yourself. Then review after at home, i find it helps alot with pointing out things to yourself that you just block out or don't even consider while your at the firing line.
What are you preparing for? Hunting, punching paper or competition target shooting? I would tackle my practice for each discipline differently.
Hunting: standing shots, and modified braced shots with a limited time to shoot, desired hit zone would be 4-6" bullseye at given range.
Punching Paper: Most comfortable position (for me its seated at the bench). Rifle braced as you want (sand bags, bipod, shooting sled etc.) Target size is up to you along with everything else.
Competition Shooting: Specific shooting position, Specific target size, Specific rifle weight, Time allow for shots ? Number of shots per string ? Practice marking your hits on the paper work ? Practice coming to the line, positioning equipment, safety protocols & shooting beside other competitors.
