Let’s see. Available 7.62 rounds in 86.

7.62 x 39 (AK round)

7.62 x 51 (308)

7.62 x 54r (Mosin Nagant)

7.62 x 63 (30-06)

Can’t think of any others off the top of my head.

Those look like a 308 and a 30-06 but you can confirm with a micrometer.

Yes, although technically it's 7.62x51 instead of .308

From Wikipedia:
Although originating from an identical preceding series of experimental cartridges, the commercial 1952 .308 Winchester and the military 1954 7.62×51mm NATO chamberings have evolved separately but remain similar enough that they can be loaded into rifles chambered for the other round, but the .308 Winchester cartridges are typically loaded to higher pressures than 7.62×51mm NATO service cartridges.[26] Even though the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) does not consider it unsafe to fire the commercial .308 Winchester rounds in weapons chambered for the military 7.62×51mm NATO round, there is significant discussion about compatible chambers and muzzle pressures between the two cartridges based on powder loads, chamber dimensions and wall thicknesses in the web area of the military compared to commercial cartridge cases.[27][28] As the chambers may differ accordingly the head space gauges used for the two chamberings differ.[29]

It’s funny. When it comes to pressure the opposite is true in 5.56 vs 223.

So always get rifles chambered in 308 and 5.56 and you can safety shoot both nato and civilian rounds.
 
The black tipped ammo in the enbloc clip looks like M2 AP, armor piercing.

Do you have a M1 Garand to shoot the ammo in the enbloc clip? If not, there's a reason to get one.

That black tip needs to be saved for special occasions.
 
I once picked up some 30.06 AP rounds that looked rather the worse for wear and tear and decided to pull the bullets and reload them. It proved to be a good idea as these were WW2 vintage meaning corrosive primers. One in five had soggy powder inside.
