Your post shows that you have a very myopic view of the world.
If your post had any merit I'd need to buy new rifles for my hunting, and recreational shooting.
If you are too weak and out of shape to carry a 10-15 pound rifle I'd venture to say that your time would be better spent on physical conditioning and diet than hunting. I say that not necessarily for your benefit but for anyone in your life that relies on you.
Me, my lightest rifle is 15 lbs. no theory here, only actual experience.
* Does it have a folder? Yes. Once I used one, I'll will always want that feature for any future purchases.
* Do I compete? No.
* Do I pack it? No, I sling carry and walk 4-6 miles on a typical day/night hunting.
* Do I have a "heavy" folder to be tacti-cool? No. If that were the case, I'd be wasting my time b/c no one sees me, since I hunt alone more often than naught.
In addition to the previously mentioned transport and storage benefits; cleaning is extremely easy, since I like a high cheek weld, I simply fold the stock out of the way for bolt removal, and no solvents end up on the stock.
So, now the 9.7-11 pound Ruger RPR is going to be a backpack rifle.
I don't think so.
These rationalizations for the folding stock on a bolt gun are going farther and farther out into left field.
And yes, silly is silly; No doubt about that.
If you look hard enough, one can come up with a theoretical use for just about anything. I'd say though, that the bottom of the barrel has been scraped clean if we are talking about ten pound backpack guns, now.
