Please excuse the few that where reposted here before, Also for lying as I do not have a DM31 (5.56), or DM151 (7.62) . But the far right is (2) DM91 (9x19), one awaiting sectioning.
You can see the three basic shapes, the first being the M993 and M995. Strait walled, flat base with aluminum pusher cup. Single bevel point.
The .338 Lapua Mag made by Finland (LAPUA) with copper "pusher" sabot, has a 2 stepped point and a notched base that indexes with the jacket to prevent the core from slipping. The MEN (German) "DM" have similar cores but would have a grey coating on the projectile itself. Much like the DM91.
Then the Swiss went with a completely different core design, shifting the weight. Most likely done to cut costs of the manufacturing of the tungsten semi carbide core itself, as it needs to be made into the shape without to much grinding.
The first uncut .223/5.56 that is on the stripper clip of "only one, need another" is a Swiss (THUN). Its tungsten core would look like a SS109 penetrator or one of the French experimental tungsten core farther to the right.
As said before, these are extremely hard to come by, even lucky to find one let alone a second to section. But when they do come around, you buy it, regardless the price. Where and when are you going to find another!
Competition for the M995(AP3) = NAMMO AP4, and the MEN DM31
Competition for the M993(AP8) = MEN DM151, MFS 2000MM-FS, Lapua AP492, RAUG P-AP
NAMMO FFV (Sweden) is currently switching to a nickel/iron binder for its cores.
