Description
If you're carrying a .38 Special revolver, you want ammunition that makes the most of what the platform offers. Double Tap's Controlled Expansion 148-grain load is built to do exactly that, combining heavy bullet weight with the increased velocity that +P pressure provides.
Velocity and penetration matter more in .38 Special than in larger calibers, and this load addresses both. Out of a 4-inch barrel, you're looking at 1050 fps with 362 foot-pounds of muzzle energy. The 13-inch penetration depth puts you solidly in the window that defensive experts recommend, neither too shallow nor excessive. The 148-grain bullet weight helps the round maintain energy downrange while still remaining controllable in typical carry revolvers.
Double Tap's Approach to Controlled Expansion
The hollow point on this load is tuned to expand reliably at the velocities you actually get from .38 Special. Double Tap handloads their ammunition with tight tolerances, holding powder charges within one-tenth of a grain. That consistency matters when you're counting on a defensive load to perform the same way every time you fire it. The jacketed construction holds up through expansion without fragmenting, which means you get predictable performance rather than unpredictable results.
Minimal Muzzle Flash
One detail that gets overlooked in .38 Special ammunition is muzzle flash. Fire a defensive round in low light and a big flash will temporarily blind you, making follow-up shots harder and degrading your ability to assess the threat. Double Tap addresses this through their powder selection, and this load produces virtually no flash. It's a small thing that makes a real difference in a defensive situation.
This ammunition comes in 20-round boxes, which matches the capacity of most .38 Special revolvers nicely for stocking a carry rotation or maintaining a small defense supply without excessive volume.

Frequently Asked Questions
What firearms can I use this ammunition in?
This is a +P load and must only be used in revolvers and firearms specifically rated for +P pressure. Check your owner's manual or contact the manufacturer if you're unsure whether your revolver is +P rated. Most modern .38 Special revolvers support +P ammunition, but older or certain aluminum-frame models may not. When in doubt, stick with standard pressure rounds.
How does Double Tap's 148-grain load compare to lighter .38 Special options?
The heavier 148-grain bullet delivers more energy downrange and maintains velocity better at distance than lighter alternatives. The trade-off is slightly more recoil, but in a typical 4-inch revolver, the difference is manageable. For snub-nose revolvers with 2-inch barrels, the heavier bullet may feel snappier due to reduced dwell time. Hand-loading discipline also means this ammunition delivers consistent performance, shot after shot.
Why does minimal muzzle flash matter in a carry load?
In a defensive situation where you're shooting in low light conditions, a bright muzzle flash temporarily blinds your vision and makes accurate follow-up shots much harder. It can also alert other people nearby to the location of the gunfire, which isn't always desirable. Double Tap's powder selection keeps flash to a minimum so you maintain your sight picture and can respond effectively if needed.
Is this ammunition reloadable?
Yes, Double Tap uses brass casings and non-corrosive primers throughout their ammunition line, making these cases suitable for reloading once fired. The quality brass and consistent dimensions mean reloaders typically report good results with Double Tap cases.
