Double-Tap .380acp GDHP wetpack test

I finally was able to do a wetpack test on the newly-released Double-Tap .380acp HP round, which uses the 90g. Gold Dot bullet. After reading the manufacturer's impressive ballistics (pushing the proven Gold Dot out of a P3AT well over 1000 fps), I was expecting greatness.



According to my usual protocol, I used a wetpack of super-saturated newsprint, bundled, and soaked overnight. I shot from a distance of about 2 yards, consistent with my other .380acp tests. I used the standard Speer Gold dot round to compare with, since I've tested that round before. I shot 3 rounds of the Speer, and four rounds of the DT, testing for penetration and expansion (measured at the widest point). As is the case in every GD bullet I've shot, all bullets expanded competely, uniformly, with no missing or assymetrical petals. Here are the results, with expected penetration in bare ballistic, following the formula that wetpack penetration is approximately 2/3 of gelatin:



l. SPEER GOLD DOT HP



A. Penetration: ave. 5.0 inches (4.75, 5.0, 5.5)--this is consistent with prior wetpack tests I've done with this bullet which has seen penetration in wetpack of 5.0-5.5 inches.



B. Expansion: ave. .50 in.(.490, .492, .530)



2. DOUBLE-TAP GDHP



A. Penetration: ave. 5.12 in. (5.25, 5.0, 5.0, 5.25)



B. Expansion: ave. .50 in. (,530, .480, .490, .490)



The felt recoil of the DT ammo is quite stout, reminding me of the old Santa Barbara surplus stuff. With that in mind, I was frankly expecting greater penetration results. In effect, the Speer and DT ammos perform virtually identically. Price-wise, the DT is a bargain compared to the Speer: the former is about $24 for a box of 50; the later is $13-15 for a box of 20.



EXPECTED PENETRATION BALLISTIC GELATIN: Approx. 7.5".



In conclusion, I expected more from the DT, although if you like the Gold Dot round, it's a more cost-effective way to go. On the other hand, the Corbon DPX still reigns supreme in the .380acp hollowpoints IMHO, with penetration numbers of 6.25-6.50 " inches in wetpack (up to 10" in gelatin), and expansion of .625".

The price of over $1/round is hard to swallow, but the performance is unmatched at this point.



BTW, unlike the unfortunate results Erich posted about, the DT ammo performed flawlessly for me, with no light-primer strikes or feeding problems, both in the wetpack test and the prior 30 rounds I shot prior to the test. Best, DT Willy
