Im looking at getting a shotgun, I will be using it off ATVs and out the sunroof of a truck culling rabbits in NZ.
Is 22" too short of a barrel and what us meant by "interchoke" Im not familiar with shotties I normally use .22lr but want to get them when they flush.
>pile of bunnies
I knew it had to be NZ the moment I saw that picture.
Also I have nothing to contribute to the thread, but have a free bump and a happy new year my fellow kiwifriend.
hawks and owls should keep the long-eared vermin in check. farmers here leave some trees along the fence line and often a big oak out in the center of a field
Not really, threads like these are usually responded to properly. There's also a lot of informative and useful stuff, just need to dig through the shitposts and memery
22 inches is fine, but for hunting get as long a barrel as you're comfortable with. You'll get better velocity.
Interchoke is just a choke system. Choke is the amount the barrel squeezes the shot to keep the pattern tight or let it open up. Choke runs from extra full (very tight pattern) to full to modified to cylinder (very wide pattern). Choke is a compromise between range and the accuracy necessary to take game.
As to bore, get a 12 gauge if you can shoot it comfortably. They have the greatest range of ammunition available and are generally more versatile. A 20 gauge will do most of what a 12 ga will, but not all.
I have two shotguns, a 12ga goose gun (long barrel, bolt action, full choke) and a Mossberg Ranger .410 with screw-on chokes. The .410 is fine for bunnies if they aren't too far out, but I wouldn't recommend it. I just hunt with it because it was Grandad's shotgun.
I got this Norinco Ithaca M37 clone for $290 this morning, it came with a set of 5 chokes. I think it will be ok for the limited amounts of time per year Ill be using a shottie.
