I think a point that still isn't getting brought up, that was very clear in the info, is that recoil vs. shootability was the driving factor of the whole conversation. And smaller bullets and they're capable sized wound channels fit into that well in regards to recoil. But recoil is the catalyst to, being able to physically shoot the rifle better. So if you bring the recoil down, with rifle weights and muzzle devices, you just bring up the caliber/cartridge and bullet weight if you want to.
He said, and I can't prove this, but above 14 ft lbs of felt recoil if where shooters start to measurably drop off in accuracy, in compromised field shooting positions. AKA, not prone off a bipod and rear rest. I believe it based off shooting my own systems though
I have a 9lb 22CM with no muzzle device. It's shooting 80 ELDM's at 3300fps. It has 9 ft lbs of recoil. It actually has legitimate felt recoil.
I have a 10lb 6PRC. Currently shooting 109 ELDM's at 3170fps. It should have 14 ft lbs of recoil, but it has a muzzle brake, so it's probably closer to 7 ft lbs. It definitely has less felt recoil than the 22CM.
I have a 10lb 7-300NMI shooting 180 ELDM's at 3160. It should have 34 ft lbs of felt recoil. But again, it has a muzzle brake so it should be around 17 ft lbs of felt recoil. I feel like this is super manageable recoil, as seen in that aoudad video. But I doubt I would shoot it as good as the 22 CM in a bunch of random field positions at say, 600 yards if I shot them side by side from many different positions. But I also doubt I would miss any vital sized targets with it, that I wouldn't miss with the 22CM
