I set a LW in .240 up for a friend. He bought it used from a pawn shop in NW CO but looked practically new.
After getting a load developed from Superior Ammo, the rifle is a drill. It shot factory ammo pretty good, notably the WBY SP, around 1" but the Superior NAB load is under 1/2".
He has a 30-06 and a 25-06 as well in the LW setup. All are pretty good shooters but the .240 is my favorite. I will get one eventually.
Had an ULW in .240 for a while--which my wife mostly used, after she found out how well the stock fit her. It shot very well too.
But part of the deal is that smaller-caliber cartridges result in stiffer barrels.
