Calculator

---

Our calculator is designed to provide you an estimate based on thousands of users feedback of how much material you would need to fill your bag, but is not a guarantee. Each shooter has their own preferences of how full a bag should be. This calculator assumes a box shape, even though most bags are not, so please provide your best estimates. It assumes 100% bag full, even though 1) that's not always the shooters' preference (depending on bag) and 2) most bags will expand/bulge as they are being filled. This also assumes zero material loss when filling. If in doubt, ROUND UP!
