Your idea is a little crazy, but since you recognize it, its not you that is crazy. Get the 240! Funny how few here are willing to answer the question you actually asked. Everybody wants to advise you. Human nature. Good luck.
Check with bullet mfgrs re twist. You may need 7.5 for the 105 & 115's.

Some of this sounds like loonies lecturing a loony on loonism...
OP already has a .25 cal, so go for something different.
I would go with a faster than std. twist if I was building a .240 or a 6-06. My .240 is a std. 10 twist and seems to shoot bullets in the 85 gr. range the best. I wish it liked 100+ gr bullets.
