I think when it comes to "reasonably priced" you're going to really get a large sample of folks weighing in. Example: I shoot Magnum Blend (#5, #6, #7 blend 12ga. 3in 2oz) and it's certainly not everyone's idea of reasonable in terms of price seeing as how it runs $30 for a box of 5--it also may not perform in someone else's shotgun/choke setup the way it does for me so it may not be reasonable in terms of price or performance. However, if it does perform for you and you shoot just two or three rounds a year you may be talking about one box of five rounds lasting 2+ years. Does <$15/year on turkey ammo sound reasonable? Only you can judge. Personally, I care more about the pattern performing than I do about the cost--I could justify or rationalize nearly any going rate for ammo if the product did precisely what I demanded of it.
