I had earlier this Summer chronographed a 10 shot string of DoubleTap 38 Spl +P 158 SWC and would like to share the results with you:

Firearm: 4 5/8 inch Ruger BH
Load: DoubleTap 38 Special +P 158 gr SWC

Shot#/MV
1. 972
2. 940
3. 921
4. 967
5. 961
6. 961 (duplicate)
7. 937
8. 931
9. 932
10. 955

Hi 972
Lo 921
Avg 947
ES 51
SD 16

Notes: DoubleTap claims a 1,000 fps from a 4 inch Ruger GP100. I’m skeptical about their velocity results. I can easily duplicate their load using Power Pistol, Unique or Accurate #5 with a generic 158 gr cast SWC. They claim the bullet is a “Keith” SWC…nope, it is a generic Magma mold type SWC, which is fine. Accuracy was good but nothing spectacular at least for me.

DoubleTap ammo used to have a reputation for hitting their advertised velocities. I guess that was in the past from what you show.

Thank you again for sharing your work with us.

What I did find is the Speer short barrel .38 +P ammo does hit the mark but that's for another thread.
