Blast only damage

What information source(s) do you have for the HG85? It doesn't seem to match any of the published information I have from many different Jane's Infantry books I have looked thru.

The sources I found are below. The last one contains scans of the HG 85 manual, though it is in German:

The filler may just be TNT, though the sources conflict on this point. Since I put up those specs above, I have found a source that claims the fragmentation liner is composed of 3mm balls, which is very close to what I calculated.

My Jane's lists:

The Arges HG 85 is the medium size in the Arges HG range. As with other Arges designs it consists of a plastic body, an inner liner carrying the preformed fragments, and a filling of PETN high explosive.

Fragment distribution covers the full 360° area around the grenade and an HG 85, detonated 1 m above the ground and 5 m from a 20 mm soft wood target gives an average fragment density of 8.1/m2.

An offensive pattern, OFF HG 85, is available and differs from the HG 85 by having a plastic core without fragments, a smooth `lemon skin' surface and being slightly lighter.

Specifications
Weight: 340 ±20 g
Length: 96 ±2 mm
Diameter: 57 ±1 mm
Weight of explosive charge: 50 ±3 g
Diameter of fragments: 2-2.3 mm
Number of fragments: ca 3,500
Delay time: 4 s +1.5/-0.5 s at 21ºC

If we want HG 85 game specs, we need to nail down at least the weight of the filler. We have 50g on the low side and 155g on the high end. Same with the grenade weight, though I was able to calculate the size and number of fragments using the 0.1g per fragment weight I found, which puts the fragments alone at 200g. I haven't looked up the weight of the DM 82 fuze yet.

Is the difference in the age of the source? It seems that the entries showing the heavier grenade are all older. The three you cited appear to contain specifications from 2003, 1995 and 1985 (ish).

We are looking at and talking about 2 different HG85 hand grenades.

The Arges HG85 (Austrian) is this version: https://www.lexpev.nl/grenades/europ.../splhgr85.html

The other version as discussed is the Swiss HG-85: https://www.lexpev.nl/grenades/europ...g85uehg85.html

This Swiss version seems to be cast and the Austrian version is molded. They both have different specs and that is what was throwing my searches off.

Ah, how convenient that they both share the same designation. But that does explain a lot.
