Description
A shooting rest is only as good as the weight holding it down, and this four-pack from Birchwood Casey gives you the ballast to keep your setup from creeping, tipping, or dancing around under recoil. Each bag is built to sit in the weight tray of your lead sled or rest and stay put shot after shot, whether you're sighting in a hard-kicking magnum or working a bench for load development.
What Makes These Weight Bags Worth Keeping in the Range Bag
The bags are made from a heavy-duty material meant to hold up to repeated hauling and hard use without splitting a seam. Each one measures 5.5 inches high by 10 inches wide by 3 inches deep and holds roughly 7 pounds of sand or about 25 pounds of lead shot when full, so you can dial in as much or as little downforce as your rest needs. Two built-in handles per bag make loading them into the tray and carrying them out to the bench a lot less of a chore, which matters once they're packed with shot.
Filling and Fitting Your Birchwood Casey Weight Bags
These ship empty, which keeps shipping weight and cost down and lets you choose your own filler. Lead shot packs the most weight into the smallest space, but plenty of folks use play sand, steel shot, or reclaimed shot to get the job done. The shape lets each bag sit horizontally or vertically in the tray, so you can stack a second bag alongside the first when you want extra hold for the heavy hitters. If you're running a lighter rimfire or a rest with a shallow tray, one or two sand-filled bags may be all you need.
Built by a Name That's Been Around the Range
Birchwood Casey has been a fixture in the shooting world for decades, and these bags carry that same no-nonsense practicality. Four bags in a pack means you've got enough to fully load one rest with plenty of media, or spread across a couple of setups. It's a simple piece of gear that quietly makes every trigger pull steadier.

Frequently Asked Questions
Do the Birchwood Casey weight bags come filled?
No, these ship empty so you can add your own fill. That keeps the shipping weight and cost down and lets you choose between lead shot, sand, or other weighted media. Just fill them, close them up, and drop them in your rest's weight tray.
How much weight can each bag hold?
Each bag holds roughly 7 pounds of sand or about 25 pounds of lead shot when filled. Lead shot gives you far more weight in the same space, which is why it's the go-to for taming heavy recoil. Sand is cheaper and easier to find if you don't need maximum downforce.
Will these weight bags fit my lead sled or shooting rest?
They're shaped to fit the weight trays on most lead sled and shooting rest models. Each bag can sit horizontally or vertically, so you can fit a second bag in the tray when you want extra hold. Check your tray dimensions against the 5.5 x 10 x 3 inch bag size if you're unsure.
What can I fill the bags with besides lead shot?
Play sand and steel shot are common alternatives, and reclaimed shot works great if you can source it locally. Anything dense and pourable will do the job. Sand is the budget-friendly route, though you'll need more bags to match the weight of a single lead-filled one.
