I do agree with you but got to make first shot count. I've got couple sporter barrel out to 27" rifles weight under 10lbs and I do pretty good 3/4 shots not a rifle you want to do volume shooting with.
You build something you want the stock to fit you and you want a balance rifle and you want that same balance if building heavier rifle. My wife shoot a Forbes rifle I have a hard time hunting with that rifle just too light.
I see guys up in the high country just watching some of the drainage for elk have some pretty nice rifles for LR were as I do more walking get up around timberline. I'm sure if I was going to build Allen mag I'd want little more weight got to balance it out to your hunting style.
