I have taken a slightly different approach when going to to brown bear country. Partially it is to do this work at the house but also to not have to deal with grouchy ROs.
I still did work in the field (charging bear targets at 30, 20, 10 yards and work my way in) but primarily relied upon this.
Items used: rifle, laser trainer (app/catridge), charging bear target
1) Set up target and training app
2) Shoulder rifle with laser training cartridge and turn away from the target
3) At the start "beep", acquire target while un-shouldering rifle and "chambering" the cartridge
4) Go for a "snap" shot on a frontal CNS-ish
4) Fire off two more "rounds" as fast as I can
5) Immediately redo steps 2-4 until I hit 10 rounds (counter for laser app)
Variants: change distance from 7-30 yards, sometimes rifle is considered "hot", sometimes I'll spin around several times before Step 3, use handgun(s) that I would take in the field, etc.
Lesson learned #1) I was not nearly as fast and accurate as I thought I'd be. Initially I'd need a 40-50 yard "heads up" to get a decent chance at a frontal CNS-ish shot. Without practice, dealing with a "just in case" scenario is a pipe dream (excluding Lady Luck intervening).
Lesson learned #2) Un-shouldering/un-holstering and target acquisition are the biggest consumers of time. Have to work these to reduce your times. Use natural point of aim rather than scope for target acquisition (worked well for me, may or many not work for others, may or may not be "proper" way of doing it).
Lesson learned #3) Still need actual field work with recoil and the joy of reloading under duress (time).
Lesson learned #4) Keep practicing until it becomes second nature and then practice more. Reference the story of the individual that used a Glock to kill a grizzly with zero warning.
This is dated but was one of my sessions for preparing for Kodiak just to provide a visual.
