I feel this ever expanding range is aimed at the USA market and all a marketing ploy. In a nutshell, as far as I can see, there are three different bullet types, the hollow nose, flat nose and standard round nose and cases all seem to be the same size. As we see from Adams recorded velocity for Team ammunition there are wild variations 1047-1100 so are there really differences in the twenty or so different types they now offer? Team, Edge, Force, Action, Biathlon Tenex, Biathlon club, Sport, Semi-Auto Benchrest Outlaw, Semi-auto Benchrest precision, 5 different pistol types etc.
I sometime have the idea they are shovelled out of a Tea chest and into what ever box is handy.
Years ago, in simpler times - there was just Tenex, Match or Club and Hollow Nosed.
It's a little bit more complex than that, to my understanding, however there are some collations with your hypothesis and what seems to be happening.
There are essentially 2 lines, there's the silver line and the black line.
This denotes the 2 types of lead/bullet.
Silver covers off:
Tenex, Team, Match
Black covers off everything else (and at a guess the hollow lines).
Tenex, Team and Match, are essentially the same recipe, same loads, bullet, brass and powder, the categorisation comes down to statistics during the creation and test process. This will be closely guarded information as to exactly what denotes each batch into which category, but essentially the most consistent and best performing ammo coming off the line is denoted Tenex, followed by Team, then match.
If the whole production is good, then you can get Tenex Categorised ammo in team or even match boxes. Tenex code is denoted by 10 at the start of the batch number.
1019 - 00000 /
1020 - 00000 /
1021 - 00000.
If your match or Tenex box has a batch number laid out like the following, it means that the bullet inside meets the criteria to be branded as Tenex.
The Tenex pistol/match etc I believe are the same as Tenex in a different box.
The round nose/black line is somewhat more complicated.
There are different powders, primer methods and bullet weights within this line.
There are Subsonic loads, and Supersonic Loads
40gr bullets and 42gr bullets
Pink Primer vs Green Primer.
And it seems recently that they've added the same kind of grading to ween out the best of these mixes for certain other products, such as the semi-auto outlaw, etc.
For the "action" rounds, I'm informed the brass dimensions have been tweaked for better feeding, however my calipers and measurements on 10 randomly selected rounds of action plus and 10 x action, showed no difference to 10 x Force, Contact or Tenex I had to hand...
There are notably different powder loads from Force to say Action Plus and 100f/ps difference avg. over a chrono.
None of this is "from the horses mouth" or from any representatives of the company, merely observations from using a lot of the products.
