$19.99 for box of 50 rounds. Cheaper than plinking ball ammo. This is top of line carry ammo at a great price.

Massammo had it for $17.99/box of 50 delivered a couple months ago.  They sold out.

That's a great price, though.

Yes, I stocked up @ massammo when they had it. Plus it was $20.99 a box not $17.99, with a flat rate shipping cost of $12.99. I checked my records from my last purchase from them in October 2016. So this case from Target Sports USA was cheaper plus free shipping. I'd wish it was $17.99ea with free shipping. I'd bought 2 cases instead. Time will tell since ammo sales are kind of flat from what I've read. Fake news?

My range ordered it at $17.99 with $12.99 shipping

Massammo had it at $17.99 with free shipping one weekend.  That's when I bought it.

Usually Wal-Mart doesn't carry .357 Sig but I was in store in a different town. They had WWB for $28.44/box. Makes these prices from TargetSports look quite attractive.
