Rifle weight is an interesting subject and perhaps the best example of, "The truth lies somewhere in the middle."
Heavy PRS rifles that weigh 22+ pounds are easy to shoot well but you wouldn't want to carry them over anything taller than a molehill. As such, they're "game guns," meaning they're built to game the system. For this purpose, they work great.
Ultralight rifles, say sub-5-pounds all-in, are a joy to carry but trickier to shoot well, especially at distance. Unfortunately, many hunters feel that they can cover more ground and be more effective with an ultralight rifle. Barring highly-specialized situations, this isn't the case. If stability is the goal, weight is an ally not enemy.
Base on decades of experimentation using rifles in the 3.5- to 13-pound zone and speaking with others with far more experience, I believe the sweet spot for active hunting is roughly 7 to 9 pounds total weight. Go below that, and you lose shootability. Go much above that weight you start feeling it.
If you need to lose weight, take off the bipod and maybe go with a smaller scope. I promise that far more elk are shot inside 200 yards than beyond.
