Straight Line Capper: Faster, More Controlled Percussion Cap Loading
Percussion caps are small, and placing them by hand can be frustrating—especially with gloves, cold fingers, or limited clearance. The straight line design helps you present caps in a controlled, aligned way so you can:
Cap your muzzleloader more quickly
Maintain better control during loading
Reduce fumbling and dropped caps in the field
Improve convenience when the nipple area is hard to reach
For many muzzleloader hunters, a quality capper is one of the most useful small accessories you can carry because it makes a repetitive task smoother and more reliable.
Compatible with #10 and #11 Percussion Caps
This Traditions capper is made to work with #10 and #11 percussion caps, two of the most common cap sizes used in percussion muzzleloading. That compatibility makes it a versatile tool for shooters who:
Own multiple percussion firearms
Use different cap sizes depending on firearm and nipple configuration
Want one capper option that covers the most common sizes
Note: Percussion cap fit can vary based on nipple dimensions and manufacturer tolerances. Always test your caps and loading tools with your firearm setup to confirm proper fit.
