Can I modify the question? Which stock handles torque the best? The high riding X-Ring style or the low riding z-rail Cerus or McMillan? I asking because I cant decide.
There’s a couple of ways to consider “handles torque the best”.
The rifle wants to twist slightly to the right when fired, with torque that originates along the length of rifling, and gets transferred to the action.
That torque’s twist is stopped by a flat bottom foreend riding on a sandbag, after the fore end digs itself a tiny bit further into the right side. (Now, it can apparently be stopped by solid immovable side bolsters as well, new rule clarification that seems like leading with the right foot again, after having just led with the right foot in the NRAs awkward rule dance).
The further a flat surface is from the plane of the torque, the less the felt twist will be on the sandbag. This is the same principle in reverse, as using a long breaker bar to help remove a barrel from an action. (You could much more easily resist a twisting action, by holding onto a longer and longer breaker bar).
If the flat surface was 3 inches below the bore, the torque applied to the sandbag would be less than if it was .75 inches.
We don’t have unlimited weight to sink into tall, massive stocks though, and in the past they couldn’t make wood that thin and long as present fore ends even if they wanted to. Since sandbags are never really pressed on, that I have seen, there’a little downside in letting them do the work. (Or side bolsters - but all the older, tall fore ends, they angled inward toward the bore rather than being braced by the bolsters, because, I think, physics was more clear to rule guys back then). I’d rather see no such rule, but if we must have them, then at least not make them self-defeating.
The converse consideration is whether you will lean on or otherwise disturb a tall rifle with your cheek, hand, shoulder, wind, etc. if a tall rifle is pushed on above its center of gravity, the tilting effect will be greater than on a low COG stock. That’s not a major consideration in F-Class, the bigger issue being that stocks can’t be enormous.
