fwiw - watched the video. At 3:15 and a while afterwards, the pig is still not dead, even with that being a small pig likely under 100#. Pretty unimpressed with that result. btw - that is a basic wild pig like we have a bunch of here.
I shoot a lot of pigs every year (and have them for breakfast most mornings) and see a lot shot. The .300 BO can work and also seen it not work. The .308 provides more consistent terminal results. An elk is a big step up.
Your .308 with a 150+ TTSX sure seems like a better choice.
Here are a couple of pig videos. Compare these to that .300 BO video with a much smaller pig.
First a .308 with a Barnes TTSX 130 grain, a 200#+ pig, then a .308 with a 175 SMK, about a 150# pig. Notice they both are dead and go straight down.
