I've been contemplating shooting the 120gr version in my 7/08 - but can't fault the current 140gr BT load at all.

Its not so much the expansion pop shot as the penetration and lack of fragmentation.
When a bullet fragments it dumps a lot of its energy hopefully in the lungs. If you watch someone else shoot an animal with the binos often you can see it ripple out from the hit like throwing a pebble in a pond. This is hydraulic shock and what causes the blood between mussel groups around the hit.
My experience is with the ttsx however I have watched a couple of kills with the tsx.
The tipped ones definitely expand(130gr 30 cal anyway) in less than 2"s of penetration down to 2200fps WITHOUT HITTING BONE.
Havent tested further out than this as thats what the amax is for.
Have witnessed a 30 cal tsx(non tipped) take out 2 red hinds(with one shot) at around 180y both had similar damage. pill was just under skin on offside of second hind.
Clearly this example shows it didnt expend alot of energy on the first animal.
His were loaded rather "soft"
Its the old E=MCsquared deal. lighter pill going faster will dump more energy in the animal(open to same diameter less sd = less penetration)

So yes IMHO you want to run barnes a step lighter than usual for cal but not because of lack of expansion. Its for transfer of shock(energy) to the animal instead of whatever is behind said animal.

Im sure Crankins 150s will do the job, but the 120 might get more bang flops.

People get all caught up in BC, its a close range pill forget bc push em hard and transfer shock.

so out of curiosity as I am looking into going the 7mm-08 route if I can get my 308 to sell what advantages will I see over the 308 with the 7mm-08. What I have read in your post I have quoted is interesting especially when you say shooting the lighter pill may give more bang flops I am only asking this as I am very curious and have had no experience with the 7mm calibers.

It was a reply to the barnes not cal. If you want bang flops high lung shot with a pill that will shock the spine. Bang flops are caused(90% of the time) by shocking the spine. neck shot or high lung shot, done right by the time the animal recovers from the paralising effect of hydraulic shock to the spine they have blead out from the lungs or jugular(if you missed bone on a neck shot)
the other 10% drop like a stone ,recover, and walk 10- 50y before keeling over. Something to watch out for.
