We wanted to see how DoubleTap’s purpose-designed defensive loads actually perform, not just on paper but in real testing: accuracy, penetration in ballistic gel, recovered-bullet condition, and on-gun feel. The lineup covered a broad defensive spectrum — a 55-grain all-copper .223, a 124-grain all-copper 9mm load tuned for deep penetration with reduced recoil, a heavy 148-grain .38 Special engineered for controlled expansion at lower velocities, and a 140-grain solid-copper .357 Magnum rated at high velocity from a short barrel.
Testing protocol was straightforward: live fire for accuracy checks and to confirm on-gun functioning, then controlled blocks of ballistic gel for penetration and wound-channel observation. When possible we recovered bullets to inspect deformation and weight retention. Shots were taken at practical distances representative of defense or field use.
.223 — 55 gr all-copper (original LE design)
What it is: All-copper 55 gr, developed for law enforcement but offered to civilians. Designed for consistent performance and deep penetration.
On the range: Accurate — the shooter noted solid, straight impacts at 25 yards.
In gel: Penetrated roughly 24 inches and stayed intact. The recovered bullet showed excellent weight retention and a clean straight path through the block, producing a wide wound channel.
Impression: Surprising for a small, fast projectile — it held together and delivered deep, clean penetration. Great candidate for hog rigs or as a defensive AR round where deep penetration and retained mass are priorities.
9mm — 124 gr all-copper (low-recoil, deep-penetration)
What it is: 124-grain all-copper, intentionally tuned to run a bit slower for recoil reduction while maintaining deep penetration (expected 15–16" range).
On the range: Good accuracy and controllable recoil thanks to the tuned load.
In gel: Produced long, consistent wound channels consistent with 15–16 inches of penetration. Bullets retained integrity and drove deep.
Impression: A solid defensive 9mm choice for shooters wanting deeper penetration without excessive recoil. Practical for concealed-carry platforms and duty use.
.38 Special — 148 gr controlled-expansion
What it is: Heavy 148-grain designed for controlled expansion at typical .38 Special velocities — optimized to get expansion and deeper penetration than many competitors.
On the range/in gel: The .38 ran all the way to the end of the gel block and stopped in the catcher; the bullet was recovered and described as “absolutely beautiful” — meaning it expanded as intended while retaining shape and significant penetration.
Impression: For revolver users who need purposeful defensive performance from .38 Special, this load delivers meaningful penetration and reliable expansion at moderate velocities.
.357 Magnum — 140 gr solid copper (1,400 fps from 4" barrel)
What it is: High-velocity 140-grain solid copper rated roughly 1,400 fps from a 4" barrel — pitched as a woodsman and defensive combo load.
On the range/in gel: The .357 went through the gel block and continued to about 27 inches, overpenetrating the block and bouncing. The bullet held together and traveled deep.
Impression: Hard-hitting and highly penetrative — useful as a woods load and capable in defensive roles where deep penetration and retained weight are desired. Expect significant overpenetration potential in some scenarios; treat accordingly.
This round of gel and range testing showed DoubleTap’s design goals translate to real performance. The company’s decision to purpose-design each load around a specific bullet and velocity yields a predictable performance envelope: deep penetration with intact bullets where intended, controlled expansion for revolver calibers, and reduced recoil in the 9mm without sacrificing terminal effect.
If you’re choosing defensive ammo, prioritize the performance traits you need — penetration, expansion, or reduced recoil — and match them to your platform and likely scenarios. In this test, DoubleTap’s lineup offered clear, usable options across that spectrum.
