+When considering fragment lethality, don't overlook that most fragmentation attacks generate multiple hits. You're not looking at trying to get a fragment to kill somebody, but at trying to get two or three or more fragments to kill somebody. For instance, a single 2d(0.5) pi- pellet from an M18A1 isn't going to kill most targets . . . but that's a highly directional device, and at the mentioned 5 yards, the average victim is going to eat seven pellets, which is rather another matter.
+As a broad rule for dedicated high-explosive munitions (not just solid ones with bursting charges), at a given TL, explosive damage goes up with the square root of explosive weight, while fragmentation damage goes up roughly with the cube root of (device weight - explosive weight). You can optimize for one or the other by altering the proportions. This is where skill comes in.
+So you could get 1-lb. devices like these:
+    *1 lb. TNT in a cardboard casing of negligible weight: 6d×2 cr ex
+    *0.75 lb. TNT in an 0.25-lb. shell designed for light fragments: 5d×2[1d] or 5d×2[1d+1] cr ex
+    *0.5 lb. TNT in a 0.5-lb. shell designed for moderate fragmentation: 8d+2[1d+2] cr ex
+    *0.25 lb. TNT in a 0.75-lb. heavy fragmentation sleeve: 6d[2d] cr ex
+The above assumes omnidirectionality. Directional devices are better modeled on shot shells.
