Or just carry a pair of ear plugs. This is what I've been doing. This also helps ensure I don't rush a shot, hunting in the west I can't think of a time I didn't actually have the time to put in plugs (even though it still seems like an unwarranted fear I think of), keep them in my pocket to keep warm, the few seconds it takes for them to expand in my ear is when I'm setting up my rifle etc.
The added weight and length to a rifle is not insignificant. It comes down the the user and what they are willing to compromise and what they want. I don't know if overrated is correct, but I think it's just a preference and the large majority of hunters seem to prefer them now compared to 20 years ago, even 10 years ago. Marketing has sure helped - shorter barrels and CF wrapped barrels and most now being threaded from the factory. A lot of the barriers to entry (or seemingly barriers) have been removed.
I will agree with
@Frequently Banned Troll regarding the suppressed .22. And even add to that, that many in the west are missing out on a suppressed fox/gray squirrel hunt in the Midwest. Out west it's fun to snipe grouse out of the trees with them, but not quite as fun as squirrels based generally on opportunity of shots given. However, I've not been impressed with the segmented HP CCI ammo which was designed specifically for hunting and being near "Hollywood quiet." The terminal performance, especially on grouse with their feather protection, is lacking, a head or neck shot is required for prompt dispatch. Same with squirrels so I switched back to using full-octane HP's. Not as quiet but kills on contact.
I've seen some integrally suppressed .22 rifles. Not sure if this is possible on a centerfire, would think if it was someone would have done this as it adds no length to the rifle. Not sure about weight because I wasn't concerned about weight when I saw the rifle at the time.
