So the fun part of sten's additions to the conversation is they are a mental trap designed to lure certain individuals here into thinking yeah thinking a certain bullet diameter is somehow intrinsically better is stupid!

So is trying to slavishly recreate an old thing no matter how much it's just not actually going to work for your new application and or platform because it's just inherently unsuitable for modern use!

Hey.... Wait a second...

Never ascribe to malice that which can be explained by stupidity. Stupidity drove the 6.8 pick over 6.5

???  None of that makes any sense as a reply to my comments about .264 USA and .277 USA.

At least your trolling is fun interesting and makes us look for how you're deliberately twisting things.

Only in your mind, have I "deliberately twisted" anything.

You could have compared 40x53mm to 25x59mmB, and noted the velocity increase of 80 percent for the 25mm AGL. I wonder why you chose not to?

Because the XM25 is firing the 25x40 mm round and not the "high velocity" version?

I mean, there is enough 40x46 mm in service (which are really "low velocity"), so if the point of Roguetechie was that the US wanted to replace / supplement the 40x46 mm with a XM25 derivative (instead of adopting the M32, with a substantial increase of the velocity and reduction of the ToF), he would have write it that way.

Not seeing how that matters.  Sten's post was mostly about the supposed superiority of 7mm caliber, which is bigger than the 6.8mm caliber of NGSW.

That's rather vague.  Who is trying to slavishly recreate what old thing?  Are you referring to Cris Murray's attempt to sell his 7mm UIAC?  Or something else?

7mm is 6.8mm is .277

It's simple

7 mm (bore) is .284" (bullet).

Which is further than 7mm than .277, so it's misnamed. This is a case where the so called "official" nomenclature is incorrect. Unless of-course 7.214mm is closer to 7mm than 7.04mm.

It is you who is incorrect.  You're displaying ignorance of the difference between caliber and bullet diameter.

     7.62mm / .30 caliber = 7.82mm / .308" bullet diameter

     7mm / .28 caliber = 7.21mm / .284 bullet diameter

     6.8mm / .27 caliber = 7.04mm / .277" bullet diameter

7.62mm NATO, 7mm Mauser, 7mm UIAC, and 6.8mm SPC are caliber designations, not their bullet diameters.

Caliber is measured between the lands of the rifling, not the bullet diameter.

First it's bullet diameter that matter, it's self evident enough. Second, even using the incorrect terminology and using bore diameter in both ways of measuring it (grooves or lands) .277 is still closer to a true 7mm. Trying to steal the limelight of the superior caliber by taking its name is the sort of underhanded tactic the Grendel cabal used to kill off the competition.

Unless you can prove a number further away from 7mm is actually closer to 7mm, then you're wrong and will remain wrong.
