Let's calculate it.
https://en.wikipedia.org/wiki/Sectional_density
https://en.wikipedia.org/wiki/7.62%C3%9725mm_Tokarev
Using this calculator https://www.vcalc.com/wiki/sectional-density

The tokarev has a diamater of 7,85 and using a bullet that is 85 grain (5.5g) then it has a sectional density of
>0.127

And if we compare that to the flintlock musket from 1686 (M4) which has average bullet caliber of 17.5mm and average bullet weight of 30.93 g (477.3 grain)
>0.144

https://en.wikipedia.org/wiki/7.62%C3%9751mm_NATO
For comparison with M80 ball in 7.62 Nato
>(7.82 mm)
>147 gr (10 g) M80 FMJ
>0.233 sectional density

So ten times sectional density 7.62x25 tokarev vs musket? By bullet diamater then no, Tip? Maybe but I dont know how to calculate that, But if we compare muzzle energy and known penetration stats (+ estimated penetration) then
>7.62x51 M80 ball
>(3,470 J)
>According to tactical effectivness of small arms 2014 by nammo then M80 ball can penetrate 3.5mm Nato plate (mild steel) at 550 meters.
>penetrates 3/8 inch (9.5mm) mild steel at 50 yards (45 meters) but fails at 1/2 inch (12.7mm) https://youtu.be/CxCc_M2fvSg?t=226
Should be able to penetrate 10-11mm of mild steel at the muzzle

>a musket with only 1752 J was noted in alan william book "the knight and the blast furnance" to still have enough power to penetrate 1mm of mild steel at 100 meters
(M4) flintlock musket with muzzle energy of 3774 J should be able to penetrate a plate no more then 2mm of mild steel at 100 meters and 3-5mm of mild steel at the muzzle.

>7.62x25 tokarev
>600 J - 700 J depending on round
>constantly penetrates ww2 era steel helmets at close range (less then 10 meters) and defeat some soft armor below lvl3A.
>penetrated SN-42 (2mm thick version) at ranges less then 40 meters when fired from PPD.
Should be able to penetrate 2-3mm mild steel at the muzzle. 1mm of mild steel consistently at ranges up to 100 meters.
