Not giving a dime to walymart
^ this
I don't like the way the cheap ones from Walmart shoot in my 11-87. I like the Remington Shurshot Heavy Dove. They shoot for me as good as higher priced loads and they're not overly expensive @ Academy, $6.79 a box. I got a flat in #7 1/2 and will probably get some in #6, just because I want to experiment with #6 this year. I have a bunch of other shells, but these work the best for me at the price point I need for the 500-700 rounds I'll shoot. Don't get me wrong, I've killed a bunch of dove with the cheap ones from walmart, but I get better performance out of these remingtons so it's well worth the extra $10-15 a case.
