the hardness has diminished somewhat. however, I've used such lead for casing pistol bullets for about 40 years and never had any problems....
In depends on the hardfacing technique and the final Fe dilution. Typical values range 42-45 HRC.
A typical steel knife would be in the 5-5.5 range on the Mohs scale.
Actually its depend on the types of pistol cartrized but its range is 30 - 60 metre.
The range of Chart is as non metallic
There are several firing ranges located in or near Manhattan. They include West Side Rifle and Pistol Range, Coyne Park Rifle and Pistol Range, Woodhaven Rifle and Pistol Range, and the Bay Ridge Rifle and Gun Range.
10ms to 560ms
Hardness is a characteristic that applies to a range of materials-metals and nonmetals alike- and is defined as the resistance of the material to deformation.

Strictly speaking obsidian is not a rock as it is not composed of crystals so can't be mineralic! It is technically a volcanic glass. It's Moh's hardness is approximately 5-6 according to the Wikipedia entry for Obsidian although an exact value would depend on the exact composition of the Obsidian in question.
@ 50m
if you are meaning as in a gun pistol you shouldn't of but it in this catergorie but a pistol looks like a L pointing the barrel to the sky which fires a range of bullets that match up to the pistol
