Questions About This Deal
Is this a good price right now? +
It is currently $30.89, against a recorded low of $27.89. Its 90-day average is $32.73. Set a price alert and we will email you if it drops.
How does this compare to other .300 Blackout ammo? +
It works out to $1.545 per round. The average across the 191 .300 Blackout listings we track is $1.415 per round, and the cheapest credible listing is $0.700. Cost per round is the only fair way to compare ammunition, because pack sizes are not standardised.
Why do different retailers show different prices? +
We found this product at 2 retailers. They buy at different volumes and run promotions on independent schedules, so the same item routinely varies between them. We show every price we find and link to the cheapest in-stock option. Always check shipping before deciding - on heavy items it can outweigh the difference.
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? +
We re-check every retailer daily and record a new entry whenever the price moves. We have 89 days of price history on this product and have logged 173 price changes in the last 90 days.
