Questions About This Deal
Is this a good price right now? +
Yes. At $40.69 this matches the lowest price we have recorded for it. Its 90-day average is $40.69. Set a price alert and we will email you if it drops.
How does this compare to other .357 Magnum ammo? +
It works out to $2.035 per round. The average across the 225 .357 Magnum listings we track is $1.227 per round, and the cheapest credible listing is $0.540. Cost per round is the only fair way to compare ammunition, because pack sizes are not standardised.
How much does shipping add to the cost? +
Ammunition ships by ground and is priced by weight, so it matters. Work out the landed cost: add shipping to the box price, then divide by 20 rounds. A pack that is a dollar cheaper but ships for more is not cheaper.
How often is this price updated? +
