Just a suggestion, & opinion.
I like that guys film & show what can be done but; a big rig on my scope isn’t for me nor would I want to even try to get to where Ted’s channel got. YouTube let’s those up because he’s #1 but he gets flagged a lot. They let it ride for him.
If you’re interested in this for yourself or friends then I’d simply set up & film on whatever set up you do have. We recently filmed through 40x96 Kiowa binoculars courtesy of Splataddict1 or whatever buddies handle is. I know his real name but it turned out pretty good. I would have preferred say a wider FOV and even though he has a heavy duty $400+ tripod, was behind to my left 6-7’ you can see the nocs vibrate when I cocked that bolt. Just gives you an idea of the shaking in filming. So besides not wanting to look through camera screen, side mount, extra weight, money, I’d have a dedicated area and film.
If targets no problem. Even my range could easily be a “pesting ” film area as Chipmunks, Rabbits, Squirrels, English Sparrows, all sit right there when I shoot groups. I don’t shoot them. I feed and watch them. Now if a Starling shows up I would but they somehow know not to. Don’t believe it? I laid (2) 12’x12’ fake lawn tarps down to catch lead. Kills weeds underneath & Worms, ants, general bugs are more than plentiful. I have to move the tarps occasionally and let earth dry out it gets so bad. But it brings in the critters & catches the lead.
Stationary idea. Hunting on the move? You may have to bite that $200 cost. If that’s what Ted used it works surprisingly well as his vibrations weren’t hard to watch. I’m more into showing that pellets can indeed Group at 200 and slugs much further. The filming Harry did years ago showing destabilizing pellets in slow motion & a wealth of info must be around. That, I would do & Youtube wouldn’t flag targets. Once anything gets killed be it a legal open season pest you know you’re gonna have to disable comments or be very kind in explaining your trying to prevent the spread of disease. Good luck whatever you do.
