Bullets
Bullet inventory tracks how many projectiles you have on hand and what you paid for them. When you log a batch, the quantity used is deducted automatically.
Adding bullet inventory
Go to Inventory and open the Bullets page. Adding inventory requires selecting a bullet from the catalog and entering a quantity. Optionally you can record a lot number, a cost per unit, a purchase date, and any notes.
Cost can be entered two ways. In Cost per unit mode (the default), you type the price per individual bullet in dollars (for example, $0.24). A helper line below the field shows the approximate total for the quantity entered. In Purchase cost mode, you enter what you paid for the whole purchase and the app divides by the quantity to compute the per-unit figure. The toggle below the cost field switches between the two. Either way, the stored per-unit cost is used for cost-per-round calculations on batches.
If the bullet you use is not in the global catalog, you can add a private entry inline from the add form. A private bullet entry requires caliber, weight in grains, and bullet type. Brand is optional. You can also assign compatible calibers to a bullet entry, which makes it appear in the recipe and batch pickers for those calibers as well as the primary one. A single inventory lot can cover multiple calibers this way. See Component catalog for how global and private entries work.
Bullet type
Bullet type is a required field on the catalog entry. It is a free-text label. Enter whatever you use to identify the construction: FMJ, HPBT, SP, hollow point, or similar. It appears on the inventory list and in the recipe form to help distinguish entries of the same caliber and weight from different manufacturers.
Multiple lots
You can have more than one inventory lot for the same bullet. This is useful when you buy from different batches and want to keep their lot numbers or prices separate. Every addition always creates a new row, so each purchase gets its own quantity and cost. Use the "Purchased on" field to record when you bought each lot.
Batch deduction
When you log a batch, the bullet quantity is reduced by the number of rounds loaded. A lot selector appears on the batch form whenever you have any bullet inventory on hand, showing the quantity, cost per unit, and purchase date for each lot. This lets you pick exactly which lot to deduct from. The lot you pick also determines the per-bullet cost used in the cost-per-round snapshot stored on the batch.
