This system was set up by the match directors who are mainly doing practical rifle competitions, long range shooting on farms, "PRS" style events, etc. and so its focus was toward common calibers used in those disciplines.
We followed the NZ FSA designation for their 308Win template being "up to 8mm" (we investigated it ourselves as well) but as I mentioned above the system isn't perfect for the outliers - hence the list above in post #3.
Caliber equivalence tables... The ricochet templates we have were set up based, generally, upon the heavier, higher BC projectiles in the various calibers we checked to give a conservative estimate of the distances as well.
It hasn't been written so far but it would be a fairly simple (though a little time consuming) task to write out under which class various calibers come under.
@Marty Henry, if the people running those big bore matches want to get in touch, I am sure we can set up a suitable template for them or do some investigation on where the various big bore calibers sit within the current templates we have. Or alternatively they will all sit under the 338Lap template ballistically.
I did set up some templates for pistol calibers - I ended up looking at cartridges like 9mmPara, 38Special, 357Mag, 45Long Colt, etc. I have started to look at the 177cal and 22cal air rifles as well but there are some powerful air rifles out there at the moment so an energy or velocity limit might have to be considered there.
@No.3, yep I completely agree - we wanted simple and simple doesn't work for everything and everyone.
