Every time I look at this gun one wonders which idiot decided .22/410 was a wonderful combination for a survival gun.

.22 long rifle? Yes. Best caliber for taking small game. No question.
.410 gauge. No. I can spit father than its effective range. You might possibly be able to take a bird on the wing with it at close range, but would it not make sense to let it settle and then shoot it?

Before anyone complains that ain't sporting, might one remind you all that this is about survival. Not sportsmanship.

To me a better combination would be .22/.303 or similar. I am sure that other people would have their own views & one would be interested to hear them. Something that will allow you to take larger game and give you a decent chance against large predators.

I grant you that recoil might be a bit stiff, but its only for one shot.

20 rounds of .303 or ..... & 50 rounds of .22 would last you for quite a long time.
