I’ve said it here before a few times. In watching/teaching hundreds of shooters over the years, shooting the same 8ish lb guns side by side with other shooters and shooting the guns back to back; with the only difference being the cartridges. And again, this predates Rokslide or any recent “small caliber” debates that get argued on here constantly…
In an 8ish lb all in hunting gun, 6.5 PRC with heavy high BC bullets is right around the recoil “threshold” for most “skilled” adult males where we start to see a noticeable drop in continuing to maintain proper shooting mechanics, properly spotting impacts through the scope, and hit rates on vital sized targets at range.
