Questions About This Deal
Is this a good price right now? +

How does this compare to other .300 Weatherby Magnum ammo? +
It works out to $2.795 per round. The average across the 36 .300 Weatherby Magnum listings we track is $3.899 per round, and the cheapest credible listing is $2.870. 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.
