Description
DoubleTap's 10mm 155-grain load sits in that sweet spot where velocity and bullet construction work together. The solid copper Barnes TAC-XP bullet does the heavy lifting here, expanding reliably while retaining 100 percent of its weight. That means you get the full effect of the projectile traveling downrange without fragmentation, which matters whether you're thinking about defense or hunting.
Performance Specs on the DoubleTap 10mm Load
This round leaves the muzzle at 1400 fps and carries 674 foot-pounds of energy. On ballistic gel, the 155-grain SC-HP produces approximately 17.25 inches of penetration with .86 inches of expansion. Those numbers work because the solid copper design doesn't depend on core-jacket separation to function. It just expands predictably from impact.
Low Flash and Recoil Benefits
Muzzle flash reduction matters more than people think, especially if you ever need to use this ammunition in a defensive situation. DoubleTap engineered this load specifically to minimize muzzle flash, which keeps your sight picture intact and prevents tunnel vision from bright flash. The recoil impulse stays manageable too, which helps with follow-up accuracy if you ever need it.
Manufacturing Quality
Each round is hand-loaded using strict powder charge tolerances held within one-tenth of a grain. The brass cases are new, non-corrosive, boxer-primed, and fully reloadable if you want to get back into handloading. That level of consistency shows when you're testing the load from box to box.

Frequently Asked Questions
Is this 10mm ammunition suitable for carry and self-defense?
Yes, the DoubleTap 155-grain SC-HP is specifically designed for self-defense. The Barnes TAC-XP solid copper bullet expands reliably and maintains weight retention, making it effective for stopping threats. The low muzzle flash design also helps maintain sight picture in defensive encounters.
Can I reload the brass from these cartridges?
The brass cases are fully reloadable. They're new, boxer-primed, and non-corrosive. DoubleTap loads these with strict powder charge tolerances, so if you reload, you'll have consistent, quality brass to work with.
What's the difference between solid copper and jacketed hollow point ammunition?
Solid copper bullets like the Barnes TAC-XP in this load don't have a jacket that separates from a lead core. They expand as a single unit, providing consistent performance without fragmentation. This design delivers reliable terminal performance across a range of barriers and target types.
Will this work in my Glock 20 or other 10mm pistol?
This ammunition is loaded to SAAMI specifications and will function in any standard 10mm Auto firearm. The 155-grain bullet weight is lighter-for-caliber, which can affect felt recoil and ballistics compared to heavier loads. Test it in your specific firearm to ensure proper function.
