The bullets recovered from gelatin are interesting. If this was properly constituted and properly calibrated 10% Ballistic Gelatin, it is obvious that the steps followed in its design to “improve performance” were a total failure, as the bullets show not one single sign of deformation. Since they are light weight, it would be interesting to know the penetration obtained in Gelatin by them? Unless the bullets followed a highly erractic path through the Gelatin, it would appear that a normal 115 or 124 grain FMJ RN bullet would be a better self-defense choice.
Nifty for a collector though.
There are a number of Fiocchi 9 mm rounds with black bullets - the following are from my own collection, so there are probably more than this:
9 x 21 mm - Both brass case, nickel primer, no PA
Black RN bullet, total cartridge weight 188.7 Grains (12.22 Grams)
Black Truncated Flat Nose, total CW 190.3 Grains (12.33 Grams)
9 x 19 mm - Brass case, nickel primers, no PA
Black RN bullet, total cartridge weight 197.9 grains (12.11 Grams)
Black Truncated bullet with Dimple Nose, TCW 167.3 grains (10.84 Grams). THIS IS LIKELY THE BLACK MAMBA LOAD IN ITS 9 X 19 MM VERSION.
Black RN Lead bullet with brass base (gas check?), Total Bullet Weight - pulled from case - 123.3 Grains - brass case, brass primer with red primer seal for “Leadless ammo.”
There is also a Leadless round with Enclosed base, 100 grain GM Truncated bullet with a small circle of lead apparent at the tip. Brass case, brass primer with red PA.
For weight comparison, a Fiocchi standard FMJ RN 9 x 19 mm cartridge with 115 grain bullet, taken from its labeled box, weighed 181.4 grains (11.75 grams) Total Cartridge Weight.
Hope this is of some interest and assistance.
