I am a precision rifle and black rifle person. I don't own a shotgun. I look down at shotguns.
But hey, you should always try what you dont understand and more guns = better.
I would like to have your suggestion for a cheap entry level shotgun. Not looking for anything fancy, just something cheap I can abuse. Eventually I will get an M4 because ... M4.
Also opinions on semi vs pump vs O/U are much appreciated.
Use would be to bring in the woods and small game, maybe turkey ?
I don't want to assume anything about what you know/don't know about shotuns...but having interchangeable choke tubes (plus some other factors like barrel length) really separates whether a shotgun is good for hunting, or not. The market is flooded with tactical/fun guns that have no choke (CYL bore) but from a hunting perspective, these are almost entirely useless. Fun, but useless. lol When considering what gun IS good for hunting, shotgunners have to ask some of the same questions rifle shooters do. What distance am I likely to encounter the target, how big is the target, how much energy is req. for a humane kill, is it moving or stationary, etc.
I'd be happy to ramble on about this because I love shotguns...but like others have suggested, a Mossberg 500 pump or a Remington 870 pump with a 28" vent rib barrel and interchangeable chokes~you'd be off to a very good start. Most of my experience (over 30 years) is with Remington shotguns...but in recent years, have come to really appreciate the lower weight of the Mossberg 500. (aluminum receiver vs steel on the 870) That said...and maybe it's familiarity...but I find the 870 far more intuitive to strip/work on. Seems spare barrels are more readily available for 870s too, so adding a $175-ish dollar, rifle-sighted slug barrel would sure be an easy upgrade. (turns your turkey/duck/grouse/rabbit gun into a deer gun in about 60 seconds)
As for action types...they all have pros/cons. I have experience with all of them/own all of them...but am no expert for sure. Here is how I see things;
Semi
Pros-fast follow-up shots, typically the lightest recoiling (action absorbs allot), great choice for migratory birds where you might be launching big 3 or 3-1/2" ers out of a blind.
Cons~price (start around $1K and go up for brand name/non Turkish guns), more moving parts (gas systems that require a little attention to keep running perfectly), physical weight, unloading live rounds
Pump
Pros~lowest cost, simple action, lots of aftermarket parts options, reliable, easy to clear a loaded round or empty mag tube, huge used market... probably more I'm not thinking of. Did I mention reliable?
Cons~recoil more stout than a semi, fun tapers off when you get up to 3" or 3-1/2" loads lol, usually weigh more than O/Us..less than semis, action is simple to use..but requires that you cycle it with authority. Not really a "con", but if you cycle it slowly...or don't fully cycle=it doesn't go boom (often called "short-shucking")
O/U~only got my first a couple of years ago..
Pros~lowest weight (great for wing shots/moving targets), ability to have 2 different chokes, great for carry, easy to make safe, easy to load/empty. Considered the "fastest handling" type of shotgun I think. Great for targets, upland birds where allot of hiking is usually required, etc. Most common gun to see at trap/skeet clubs
Cons~cost, limited to 2 shots (only 3 allowed anyway, most guys don't see this as a negative)
