Let’s see that’s about 300fps, give or take, less than a standard .22lr round.
In high school the rifle team practiced with standard ammo but on the day before the match, I think, and on match day thry had match ammo. The match ammo was Remington, IIRC, and had silver cases. According to the rifle team coach, MSGT Johnson, the match ammo was slightly slower than standard and made with more precision. The only way you could tell the two apart was the match ammo had silver looking cases. It also cost more than the standard but I don’t recall the difference.
I have heard of the sub-sonic ammo not functioning well in some semi-autos.

Yes, the subsonic load probably is insufficient to cycle the semi auto, plus the long lead projectile tends to foul in sharp feed ramps.
It’s still an interesting “specialty” round.
