Quoted:
Anyway, if I had to order shotgun components, I would buy value packs of loaded ammo on sale at Walmart instead. I prefer to reload, but I have to draw the line some place.
The Federal and Winchester promo loads use hulls that are apparently terrible for reloading. The Remingtons are a bit better and should use STS data. They don't have the longevity of an STS hull though.
For those who need hunting loads, or something besides 12ga #7.5 birdshot, shotshell reloading can be very economical.
OP, Gamaliel and Ballistic Products are some of the better places for shotshell specific items, although Grafs, Midway, Wideners, Powder Valley, and Midsouth are good too.
Shot can be very expensive to ship unless you buy it by the pallet. Look into reclaimed shot in your area.
