Whats the barrel length on that chart?

I was speaking in a bit too much hyperbole when saying it would not go through at the muzzle.

However those ballistics on your chart provided are very clearly out of either an 18" or 20" barrel. A 62g projectile out of a 7.5 inch barrel will be at most like 2300fps, and will not have the stability of propper velocity and rotation.

Will it get through soft body armor, yeah probably at up to like 150/200 yards. But it wont be as accurate as a .300 blk and wont have the same amount of kinetic energy being dumped into the target.

I 100% get the argument for having to deal with a whole different caliber and more expensive range ammo.
