How to compare powder and primer prices across stores
The cheapest shelf price doesn't always make the cheapest order. Compare in the same unit, then count what it costs to get the order to your door.

Compare in the same unit
Stores list the same powder in 1 lb and 8 lb jugs, and sometimes in kilos. Pack prices can’t be compared directly, so convert them first:
| Pack | Price | Grains | Per grain |
|---|---|---|---|
| 1 lb | $42 | 7,000 | 0.60¢ |
| 8 lb | $280 | 56,000 | 0.50¢ |
The 8 lb jug looks expensive and saves about a sixth on every grain. Do the same for bullets, primers and brass by dividing the price by the count. Check that a “box” really holds what you assume, since bullet boxes commonly hold 50 or 100 and the listing may not make it obvious.
Why hazmat changes the answer
Powder and primers are hazardous materials in shipping, so stores usually add a hazmat fee per order on top of normal shipping. The fee doesn’t depend much on how much you buy, which has two results: small orders are costly per unit, and splitting an order across stores can mean paying the fee twice.
Say you need 1 lb of powder and 1,000 primers. Store B has the cheaper primers:
| Store A | Store B | |
|---|---|---|
| 1 lb powder | $38 | $41 |
| 1,000 primers | $85 | $80 |
| Hazmat fee | $40 | $40 |
| Shipping | $15 | $15 |
Buying both from Store A costs $38 + $85 + $40 + $15 = $178. Taking the cheapest of each means powder from A ($38 + $55 in fees) and primers from B ($80 + $55 in fees), which comes to $228. Saving $5 on primers costs an extra $50.
What else to check
- Stock. A low price on something out of stock doesn’t help. Note when the price was last seen, too, because component prices and stock can change quickly.
- Free shipping thresholds. These often exclude hazmat fees, so read the conditions.
- Limits and local rules. Some stores won’t ship certain items to certain places. Check the store’s policy and the rules where you live before counting on a price.
- Lot size. Buying more powder at once can mean fewer lots to rework a load for, which can be worth more than a small saving.
Putting it together
Once you know what an order really costs, carry it through to the round. How to work out your true cost per round shows how, fees included.
