If you supplied up on reloading components a few years ago, a box of 12 ga target loads is $4-5.
Two years ago Reeds had a sale on Federal Gold Medals. $42 a case. I bought two pallets full (100 cases). You can't reload with quality components for anywhere near that price. People never add in their time when figuring the cost of reloading ether. Time is money.
Stock up when they are cheap.
Estate and Top Gun are the same thing and plenty good for trap unless you're a Olympic class shooter.
I think they suck for sporting clays
