I was looking at my daughter's CVA Hunter single shot (.243) the other day and it got me wondering why someone isn't producing a lightweight takedown hunting rifle for backcountry hunters. Her CVA isn't exactly light, but that's mostly because it has a pretty heavy barrel contour. It takes down with one screw and can be stored in a standard backpack with ease.
I can see a company making a similar rifle with a lighter barrel contour, and a thumb screw takedown system that has a torque limiter like a torque wrench so that you use the same amount of torque on the forend every time you re-assemble the rifle. The scope would stay with the barrel, like it does on my daughter's CVA. Heck, you could even have storage for extra shells or cleaning gear in the hollow stock.
Being able to stuff it in a backpack would be pretty nice for a lot of situations, and let's be honest, it's the first shot that really matters. If you have a shell carrier somewhere handy, getting a second shot off with a break-action single shot isn't that much slower than a bolt action.
So why doesn't this rifle exist? I can think of at least one situation where I would only be allowed to carry a weapon in my pack through some public land to get to another type of public land where I can actually hunt. I've already checked the regs. and called the office, and they said no problem, so long as the weapon stays in the pack on the way through their property. Right now, if I did that I would have to take my daughter's CVA Hunter .243.
