Hello. I got the opportunity to try one of the newest versions of ammunition for this fine old revolver round.
The only revolver I have that is chambered for .45 Colt is this S&W Mountain Gun and it was used for my informal tests.
In a nutshell, this stuff expanded very consistently and penetrated well in super-saturated newsprint.
The DPX's average penetration depth in the "wetpack" was 8". Mike Shovel at Corbon advises that in the gold standard of expansion media (10% ballistic gelatin), that this bullet penetrated roughly 15" after punching through 4 layers of denim. On the left is the DPX. On the right is Corbon's 200-gr. JHP +P, which uses a Sierra hollow point.
The DPX lost virtually no weight in the newsprint and expansion was most consistent. The average expansion characteristics shook out at 0.879 x 0.867 x 0.614" tall.
Accuracy at both 15 and 25 yards was more than acceptable; in fact, it was quite accurate and capable of better grouping than I am shooting from a rest.
For those interested in a more detailed report and a look at Corbon's conventional 200-gr. JHP +P in this caliber and how it compares to the DPX, here's a link:
