My experience is similar to what you worry about...although thats nothing to worry about...lol...
Though i dont shoot pigs--none here that i have access to--i just try shoot goats if i get the opportunity & i very occasionally hunt the odd herd of paper-skinned coreflute with it in a particular paddock out to 400 yds...
I basicslly found similar weight bullets in different brands were designed differently...
For example, the 7mm Nos BT from memory is supposedly a shift up designed for heavier animals (heavoer base/maybe thicker jacket i guess
) where as the 120 Vmax was still a varmint type with rapid explosive expansion still at slower speeds.. . (Better for soft little goatoids)
Best results i got on goats were with 120 Vmax...
Although the 140 weight is toated as the "alrounder", i prefer those 120 vmax for goats...every goat ive ever hot with them has fallen over immediately--ive never had a run-on with them.
The latest im trying is speer 110 hp's that seem ok, but ive only head shot in close proximity so cant realy say how they perform until i hit a few in the chest at decent range...
I found the sierra 120 GK very explosive on skulls (head shots) under 80 yds (no head left lol) but i found they pencilled through their little ribs & soft chest cavities...
Having said that, i know of a bloke who (apparently) shot squillions of goats with this bullet & loved them...!!...but he was slso driving them faster than i was.
Ive only found loads for my 7-08 either down very low or right up high (100%-compressed loads) so i choose the low end as the other were very loud & really hammered the brass to the point of having to FL size every firing...bugger that...!!...
There is a projectile for every need in the 7mm range--you just need to find one that performs well for all your game choices, based on the speed you're sending them at....but that is the case with every cartridge when hunting...
There's many people with so much more experience than me with 7-08...hopefully you'll hear from them...
I like it...& i doubt you'll be disappointed...!!
Just one thing to be aware of...!!
If you're going to get your cartridges mixed up & put in wrong rifle on the bench...make sure you put a 243 in the 7-08...not the other way around...lol..
One thing ive learned using 308 cases in my 7-08...depending how tight the chamber is & how thick the brass is, you may have to turn some necks...
So make sure you measure the necks of loaded rounds & the fired cases, along with a bullet slip test in a few fired necks of any batch...
Or you may chase your tail & scratch big holes in your head wondering why a bullet that grouped beautifully with one batch of brass, sprays like a hand full of rocks with another batch...(meaning it could get dangerous with pressures if the brass is too thick)
The man who knows everything, doesnt really know everything...he's just stopped learning...
