So you are literally comparing a shoulder fired gun to a tripod mounted crew served AGL and saying "oh yeah if muzzle velocity was so important with computer gunsights why did the US Army  dramatically reduce the projectile mass of the 25x40mm to achieve a V0 that isn't even quite as high as an AGL's? Checkmate, atheists!"

Sorry, but I'm not the one who made the comparison (XM25 vs. Mk47), I was just a guy replying to him...

He said "something like an XM25", he said nothing about using the same caliber. Just seems... A little obtuse to not get that?

Whether or not it is or is not "right" is a matter of opinion.

However, the convention of bore size = caliber is a reality. 

What was it you said about the people who deny reality?

Or maybe the whole point of velocity being not so good because of the handcapty in weight, recoil, cost and complexity should be obvious. The go fast boys would want our troops carrying tripod weapon int combat because the muzzle velocity certainly makes up for it... that post exemplifies it perfectly the advantages of a sensible solution.

Are you going to explain why 7mm (.284" bullet) is the "ideal" caliber?

Maybe you should educate yourself more and read the work of Mr. Murray, he does that better than anyone else. But basically it's the ideal compromise of range, stopping power, recoil, etc for a rifle. It's the one size missing until now.

When Murray talks about 7mm being the ideal caliber, he's referring to .284" diameter, not .277" diameter. 

So, if NGSW does get adopted, we will have a caliber that's smaller than his supposed "ideal" (7mm) caliber.

And yet my follow on comment is still dead In the x ring since we discussed this here when these articles first hit...

How is it that one of us works for an actual MOD and they're the one that's shockingly more badly informed?

We need something with oh I don't know between a 22 and 24 inch barrel that does oh let's say no more than 2600 fps and is let's just call it between 270 and 280 caliber.
