So I am going to get a shotgun, probably a pump (Moss/Rem), if things calm down to a reasonable level. I want to use it for clays and possibly HD. Although I have a dog 1st, and .357 2nd. The wife should be able to use it as well, she's recoil shy, so the less the better. Am not planning on hunting anytime soon, and if I do decide to do that, it would be birds, rather than deer. Would a 20 ga suffice for clays? Is 20 ga ammo cheaper & easier to find?
