Heavy Bullet Subsonic Rounds
Anyone try them for Bullseye I don't know if there is any advantage but I don't know there is no advantage?

I've shot some Fiocchi. Nothing special.

Practically everything we shoot in .22 for Bullseye is subsonic. The speed of sound varies with temp, humidity, barometric pressure etc. But it is usually figured at around 1125 fps. If you shoot SV then you are already shooting subsonic rounds.

I believe that the CCI Subsonics that I looked at were around 800 fps. They were double the cost of standard velocity so I did not get any to test.

No advantage over SV for most applications. Since it's a heavier bullet, 45 gr, going 1090 fps, there is more muzzle energy compared to SV. More muzzle energy = more felt recoil. While it's not a huge difference it is greater. But it might help those automatics that have difficulty digesting SV ammo while still maintaining subsonic velocities.

Just to let you know;
Legal .22 ammo is 40 grains max. as per the NRA rule book the last time I looked.

That's the way I remember it also. But, I looked last night and again just now and can not find that in the rules anymore. They might have changed it or forgot to put it in there. I was going to mention that last night and quote the regulation. As hard as ammo is to find they may be changing the rules (again). The CMP still has the 40gr limit ( 6.5.2)

Well; I just found this.
Looks like 3.4(a) says it is okay now.
