It depends on what you want/are willing to buy at one time. If you get case prices, you can cut your costs down a little more.
Walmart also has those 100 round bulk packs of Winchester and Remington promo loads, as long as the shot size is allowed in your league.
It might be just me, but I think that Winchest AA and Remington STS seem to burn cleaner? I shot a couple of hundred rounds of Estate promo loads last fall and both of my guns were covered in a greasy soot and had to be stripped down and fully cleande. I’ve never seen anything like that after just 100 rounds per gun. Maybe it’s all in my head, but I’m sticking to AA from now on even if they cost a little more.
