hi guys : i truly like my m-6 survival rifle..its in caliber .22 hornet and .410 gauge..the hornet is a hard hitting round..and the rifle can shoot different types of .410 loads ie..shot or lead pumpkinballs..it also has a small magazine in the stock for the rounds..and the weapon can be folded or broke down in two halves to fit in your rucksack etc...the down side is that the .22 hornets cost alot for just 20 rds....vince g.
