You bet! That is one of the benefits of this program vs. buying straight from the store. You can trade into another caliber at any time (as long as we haven’t shipped it to you). The way this works: we will trade your current caliber for 95% of the new caliber (the 5% is our fee for the exchange). We use the price we are currently selling the same rounds for on our product pages and inventory .pdf to calculate the prices.
