When it comes to shotguns buy a 12 gauge if you don't reload. You can buy 20 gauge and 12 gauge shell for the same price but you get more bang for the bucks with a 12 gauge. Also you get a bigger selection of options. I grew up in Ohio and at that time was only allowed to use shotguns for rabbits to deer. (It was legal to use 22 rifle on squirrels then but used shotgun anyway). I still have my MEC 600 Jr in 12 gauge that my Mom bought me for Christmas when I was in high school. It cost $34 plus $15 for the optional primer feeder. Back then there was no Wal Mart or bulk ammo so I loaded Winchester 12 AA using Red Dot. A case was 500 rounds then also. Today I like to shoot five station sporting clays and some trap at our local county range. Just for fun. Most people in Wyoming own guns but not shotguns. Most of the people I shoot shotguns with are not originally from Wyoming. For many years I used a 12 gauge and still do occasionally. I only use store bought ammo for that because I can't reload 12 gauge for that. I like the 28 gauge. I learned that if I am on a 28 gauge is all I need. If not it doesn't matter what I use. If you shoot factory new 28 gauge you will pay $10 and up for a box of 25. That is 40 cents and up per shoot. By loading I get my cost down to 20 cents a round. Since I am going through all the "trouble" to reload I might as well go for it. I use Pro Reach and get 1425 fps! This is one bushing down size because I was getting 1485 fps. I may not have a lot of BB's at 3/4 oz of shot but at that velocity if I get one pellet hit I will get a visible piece. I could do the same thing with Pro Reach in a 12 gauge but the recoil would add up. Right now I am at 44 magnum recoil level per shot in a six pound O/U. I can handle that. BTW I got out my old MEC 600 Jr in 12 gauge and loaded up some really reduced OO buck loads for my sister in law's 12 gauge double barrel shotgun. You got to love the 12 gauge versatility. I made this for her. I cut down the barrel and stock to fit her. Put a thick recoil pad. It replaced her 410 single shot house gun.
