I think it got pushed out the by 6.5x284 Norma.
My very first long range cartridge was a 6.5x55 Carl Gustaf Mauser '96 with 24" barrel. Back then (1990) we shot Swedish military 139g FMJ at 500 metres, 600 metres and 800 metres in our military rifle competition. At that time, due to the amount of surplus rifles in Australia, that and the 303 were most popular, the 6.5x55 was far flatter shooting and was a great performer. The Swedish ammo was not anaemic like US factory ammo, was Berden primed and very accurate, It was surprising that it would often print .5 MoA groups.Not much love expressed for the older cartridges like this, but what a beauty: (https://www.longrangehunting.com/threads/6-5x55mm-bjai.136371/)
I just gave my Swede M96 to my son, he's been asking for it for years. It's a death ray, amazingly accurate with the old Sierra 160gr SPRN GKs and diopter target sights, it also has the micro-target sight on the service ladder sight. At 100 yards it's always in that 3/4" to 1/2" moa range, the trigger on this one is glass smooth. CheersMy very first long range cartridge was a 6.5x55 Carl Gustaf Mauser '96 with 24" barrel.

The AI version is just more of a good thing if using modern pressures.
