5 Common .38 Special Ammo Mistakes to Avoid for Better Shooting

The .38 Special has been around since 1898, and it's still one of the most popular revolver cartridges out there. Whether you're carrying a classic Smith & Wesson, practicing at the range, or teaching a new shooter the ropes, the .38 Special is reliable, manageable, and effective. But here's the thing – even experienced shooters make mistakes with this cartridge that can hurt accuracy, damage their firearms, or create safety issues.

Let's walk through five common .38 Special ammo mistakes and how to avoid them. Your gun (and your wallet) will thank you.

Mistake #1: Running +P Ammo in Non-Rated Revolvers

This is probably the most common – and most dangerous – mistake shooters make with .38 Special ammunition. +P ammo is loaded to higher pressures (up to 20,000 PSI compared to standard 17,000 PSI), which means more velocity and energy. Sounds great, right? The problem is, not every .38 Special revolver is built to handle that extra pressure.

Vintage revolvers, particularly those made before the 1970s, often weren't designed with +P pressures in mind. Guns like older Colt Police Positives, early S&W models, or budget revolvers can experience accelerated wear, cylinder timing issues, or even catastrophic failure when regularly fed +P ammunition.

Even some modern lightweight revolvers chambered in .38 Special have warnings against using +P loads. The aluminum-framed snubbies might be rated for it, but constant +P use will beat them up faster than standard pressure rounds.

How to avoid it: Check your owner's manual or contact the manufacturer to verify your specific model is rated for +P. If you have a vintage revolver or aren't certain, stick with standard pressure loads. Your gun will last longer, and honestly, standard .38 Special is plenty effective for most applications anyway.

Mistake #2: Ignoring Carbon Buildup in .357 Magnum Chambers

Here's a sneaky one that catches a lot of shooters off guard. If you own a .357 Magnum revolver (or rifle), you can safely shoot .38 Special in it – the chambers are cut for the longer .357 case. But there's a hidden cost to this practice.

When you fire .38 Special rounds in a .357 chamber, the shorter .38 case leaves exposed chamber space ahead of the case mouth. Carbon, powder residue, and crud build up in this area, creating a "carbon ring" where the .38 case ends.

Shoot enough .38 Special without cleaning, and this carbon buildup gets thick and hard. Then when you try to chamber a .357 Magnum round, the longer case hits that carbon ring and can stick, refuse to chamber properly, or even get stuck during extraction. Some shooters have ended up with cases wedged so tight they needed a gunsmith to remove them.

How to avoid it: If you regularly shoot .38 Special in your .357, commit to frequent and thorough chamber cleaning. Use a bronze brush and solvent specifically designed to remove carbon buildup. Some shooters keep their .357s exclusively for magnum loads and use dedicated .38 Special revolvers for practice – not a bad strategy if you've got multiple wheelguns.

Mistake #3: Choosing the Wrong Bullet Weight for Your Purpose

The .38 Special is available in a wide range of bullet weights – typically from 110 grains up to 158 grains – and picking the wrong one for your intended use is a common mistake.

Lightweight 110-125 grain bullets move faster and have less recoil, which makes them popular for practice and competition. But for defensive use, they might lack the penetration needed, especially from snub-nose barrels where velocity drops significantly.

On the flip side, heavy 158-grain loads (particularly the classic lead round nose) have great penetration but can be slower and have more felt recoil. For small-framed shooters or anyone struggling with recoil management, these heavy bullets might compromise follow-up shot speed.

The traditional law enforcement load – the 158-grain lead semi-wadcutter hollow point (LSWCHP) – has proven itself over decades. For defensive carry, modern 125-135 grain jacketed hollow points from quality manufacturers offer an excellent balance of expansion and penetration from short barrels.

How to avoid it: Match your bullet weight to your purpose. For practice and plinking, lighter and cheaper is fine. For defensive use, invest in quality defensive ammunition and test it in your specific revolver. Bullet weight matters, but bullet design matters more – modern defensive hollow points in the 125-135 grain range typically perform best from snub-nose barrels.

Mistake #4: Ignoring Lead Fouling from Unjacketed Rounds

Lead bullets are awesome for .38 Special – they're accurate, affordable, and perfect for practice. But they leave deposits of lead in your barrel, and ignoring this buildup is a mistake that affects both accuracy and safety.

Lead fouling accumulates gradually, especially if you're shooting a lot of rounds. As it builds up, accuracy suffers because the rifling can't grip jacketed bullets as effectively. In extreme cases, excessive lead buildup can actually increase pressures.

The problem gets worse if you mix lead and jacketed bullets in the same shooting session. Firing jacketed rounds over heavy lead deposits can strip chunks of lead that travel down the barrel, potentially causing even more problems.

How to avoid it: Clean your revolver barrel regularly when shooting lead bullets. Use a proper lead removal solvent and a bronze brush (never stainless steel, which can damage your barrel). If you shoot a lot of lead rounds, consider using a Lewis Lead Remover or similar tool designed specifically for removing lead fouling.

Some shooters alternate between lead practice ammo and jacketed rounds for carry – just make sure to thoroughly clean between switches to prevent issues.

Mistake #5: Poor Storage and Using Corroded Ammunition

This might seem basic, but you'd be surprised how many shooters have boxes of old, corroded, or improperly stored .38 Special ammunition lying around. Unlike centerfire rifle cartridges that get cycled through regularly, revolver ammunition often sits in a nightstand drawer or range bag for years.

Ammunition exposed to moisture can develop corrosion on the case or primer. Green or white corrosion on brass cases isn't just ugly – it can affect chamber fit and extraction. Corroded primers may fail to fire reliably, which in a defensive situation could be catastrophic.

Additionally, ammunition subjected to extreme temperature swings or stored in humid environments can experience powder degradation, leading to inconsistent velocities and accuracy issues.

How to avoid it: Store your .38 Special ammunition in a cool, dry place. Use ammo cans with desiccant packs if you live in humid climates. Rotate your defensive ammunition annually – those rounds have one job, so don't trust your life to five-year-old carry ammo. Inspect rounds before loading – if you see corrosion, discoloration, or deformed cases, don't shoot them.

The Bottom Line

The .38 Special is one of the most forgiving and reliable cartridges ever developed, but it's not immune to user error. Avoid these five common mistakes, and you'll get better performance, longer firearm life, and more enjoyable shooting sessions.

Remember: use the right ammo for your specific gun, clean thoroughly and regularly, match your ammunition to your purpose, and store everything properly. These aren't complicated rules, but following them separates casual shooters from serious ones.
