Caldwell Universal Rear Shooting Bag Unfilled
The Caldwell Universal Rear Shooting Bag (Unfilled) is one of those simple range bits that quietly makes your shooting way more stable without overcomplicating anything. It’s basically a tough leather-and-polyester rear support bag that works with most front rests and gives your rifle a steady, non-slip cradle when you’re zeroing or shooting from a bench. It ships empty, so you fill it yourself with sand or similar material, which means you can dial in the exact weight and feel you want. The outer leather contact surface helps it grip your rifle without marking it, while the synthetic body holds its shape so it doesn’t go floppy over time. It’s not flashy, but it does the job properly if you want repeatable, stable shots without spending loads.
