I'm not an expert archer by any means but have a bit of background in "stressful shooting situations". What I have learned is to react well in those stressful situations is to train under the most realistic ones you can. Adrenaline blackout I'm not familiar with but the bodies physical reaction to what you describe is increased heart rate, narrowing of vision, blah blah blah.My suggestion and practice is shooting under pressure. Run hills in between shots. Don't have a lot of room try 20 burpees and take a shot with no rest and repeat it. When you have multiple shoots on animals in a weekend your stress isn't going to be there because no one really gives a darn about small deer and piglets.My two cents
My misses on bulls in the past were a result of buck fever. Funny part is I didn't get buck fever when launching an arrow at a deer. Just an elk. Part of it is I've been surprised by a bull showing up when I wasn't expecting him, multiple times (yes it can happen). I think the other part of it on those first bulls was just the sheer size and proximity. That's when buck fever took over. Didn't use range finder, and "guessed" the range as I was in a hurry....brain wasn't functioning like it should in that moment. Shot low every time, on my first few bulls experience. Only way to get over it is more experience at elk hunting, at least for me. Also my 3-D targets in the yard were all deer. One challenge I had with elk is range appears different with a bigger animal than a smaller one, and my brain was calibrated for deer size targets. So I spent more time shooting at larger targets to help calibrate my brain better.I don't think shooting deer or pigs will help you with elk. But, that is just based on my experience. We're all different.
If you have the resources, there are several states where you can get reasonably affordable deer tags in multiples. The flip side is that if I shot 3-4 deer I wouldn't need an elk in the freezer on top of that. I think there is a guy on here that hunts waterfowl with a bow, so there are small game options as well.Other options are to do shooting drills where you have tons of activities - do 20 burpees fast and then crank off a shot within 10 seconds (or whatever number is challenging). Just being in better shape helps accuracy.3D shoots where people are watching you and there are semi-realistic scenarios (shooting up, down, around trees & bushes, etc.).Finally, just shoot more. If you can regularly shoot all year you will have better hold muscles, more muscle memory and the ability to focus on the elk and your aim point instead of thinking about the mechanics of the shot.
