The grip has zero relevance to the shot being taken
The only thing that matters, is that you shoulder it properly
and you find a way to repeat your hold on the bipod, which you can only do with load.

My main grip with his position would be that he cannot load up his bipod on a wooden table.
and risks that it greeps or jumps forward if he does.

You cannot do a posistive repeat hold if you simply rest the rifle on the bipod.. so your shot repeatability is less guaranteed.
Sand bag in front of the bipod and load up.. or use a table with some kind of ledge to it, or with planks sideways and bipod in between the joins somehow.


I used to shoot out 300 winmag 1000-1400 yds.
You don't need the grip. grip is really the least of the concerns for long range.
It cannot add anything useful to the big mix of variables.

come think of it, his thumb in that location, is how you would shoot if your rifle doesn't have a real pistol grip but a regular rifle stock. So that just maybe what he normally shoots at longer range.
