Is there any real difference between these?

Why does Russia opt for the 125mm while Western nations stick with the 120mm?

LoL just to show theire citizens that russian tanks are better .
Russia always using a bigger caliber then NATO kind'a I think they still thinking they are in a cold war

Why shouldn't they use that calibre? They dont need to follow Nato standards.
I dont think these 5 mm make any real difference.

From a period that bigger meant better, that's 5 mm. better. LoL.

quite amazing, isn't it? There we had the bigger, but definitely not better german A7 tank in WWI, various attemts to get better by making things bigge, from overheavy tanks like the russian Klim-Woroshilov, over Königstiger and Maus to Monstrosities like the Rat. Than, after WWII we build lighter hardware, 20 and 30mm autocannons have been fine for decades, the 105 mm maingun was fine for decades, and now we are back to?
Yup. getting bigger, the MBTs get heavier, the guns bigger calibres, I wondeer when its time for Big Berthas rebirth.

ummm...hell yeah 5mm makes alot of difference

Which was also the single most scare vehicle Germans encountered in 1941 and single handedly stopped entire brigades for hours.

Actually the 105mm was never fine, the West was behind Russia in tank design for decades and there was a ridiculous minimalistic approach to armaments.

150mm are coming, Koreans have an option to build it into their tanks, Americans and Germans are quietly considering a new generation of tanks with a 150mm main gun, Russians too though in their case its more of wishfull thinking.

Hope Krupp (I think its Rheinmetall now) didn't lose the blueprints for the Big Bertha. Ansd maybe we can mount some 400 mm guns on the ne frigates. The MONARC Project looked quite promising, but still a small Calibre if we want to do it as bigger as better way.

There's no point for these kinds of guns, anti-ship missiles can make a mangled mess of any ship in a manner which makes capital ships artillery look weak.

As for railway guns, the whole idea was to deliver a big boom over a massive range, today we can do that with improved explosives in 120-150mm artillery and with rocket propelled shells they can reach over 50km of range so beyond the cool factor huge artillery calibers are useless both on land and on the sea.
