Smyth Busters: Will Shooting Jacketed Ammo Clean My Barrel?

Published on October 12, 2021
Duration: 1:56

This 'Smith Busters' episode debunks the myth that shooting jacketed bullets can effectively clean lead fouling from a firearm barrel. While jacketed bullets may remove some powder residue and lubricant, they primarily iron lead into the barrel's grooves rather than removing it. For proper lead removal, using a dedicated lead solvent and brushing is recommended. This is particularly important for .22 rimfire conversions in AR-15s, where wax and lubricants can build up, impacting accuracy when switching back to centerfire ammunition.

Quick Summary

Shooting jacketed bullets does not effectively clean lead fouling from a firearm barrel; it tends to iron the lead into the barrel's grooves. While they may remove some powder residue, proper cleaning requires a dedicated lead solvent and brush. For .22 rimfire conversions, cleaning wax and lubricants is crucial for maintaining accuracy when switching to centerfire rounds.

Frequently Asked Questions

Can shooting jacketed bullets clean lead fouling from a firearm barrel?

No, shooting jacketed bullets does not effectively clean lead fouling from a firearm barrel. While they may remove some powder residue and lubricant, they tend to iron the lead into the barrel's grooves rather than removing it. Proper cleaning with a lead solvent and brush is necessary.

What is the best way to remove lead fouling from a gun barrel?

The most effective method for removing lead fouling from a gun barrel is to use a dedicated lead solvent and a suitable brush. This process physically dislodges and removes the embedded lead residue from the barrel's rifling.

Does shooting jacketed bullets help with .22 rimfire fouling in AR-15s?

When using .22 rimfire conversions in AR-15s, shooting jacketed bullets does not address the primary fouling issue, which is typically wax and lubricants. It's crucial to clean these residues out before switching back to centerfire cartridges to maintain accuracy.

Why is cleaning a barrel important after using .22 rimfire ammunition?

Cleaning the barrel after using .22 rimfire ammunition is important because the waxes and lubricants used can build up. This buildup can negatively impact accuracy, especially when transitioning back to centerfire cartridges like 5.56/.223, leading to wider groups.
