It is, the ranges mark up the ammo (what business doesn't) as they sell small quantities to a captive audience who will pay. Ammoseek represents the other end of the spectrum, ppl buying wholesale in larger quantities. Not represented are the hand loaders, typically sports-oriented going through a thousand a week in practice buying components at cost.

That is fair, you can expect to pay double for the convenience of buying on site at a staffed range.
