I have a NEF handi rifle that I really like. Single shot break open with iron sights
in 30-30 caliber. Ammo anywhere like a 30-06 but lighter to carry a bunch of cartridges. Cheaper ammo too. With handloads of spitzer bullets it has a point
blank range for big game of about 250 yards. Compare to a 30-06 of about 325 yards.
1 phillips screw and you can remove the barrel for cleaning or carrying in a pack and I sent it back to the factory and they made a shotgun barrel that fits the
receiver too. They come in many calibers and the rifles cost about $200. Weight
of the rifle 7 lbs. Weight with the shot gun barrel mounted 5 1/2 lbs. Short
and well, handy. They also come in 22 hornet up through 450 marlin in centerfire.
A few models come with Stainless barrels with stainless/nickel receivers
and synthetic stocks. Heck they even have a model called "the Survivor"
