Blackfork is trying to develop subsonic loads for his .223:

I looked on the Hogden site and found a subsonic load: 3.1 grains of Titegroup and a 55 grain bullet. I tried 3.1 grains of Titegroup under a Nosler 69. It works, doesn’t cycle the rifle but it’s quiet. The gun kind of rattles a bit when it goes off. Kind of a beefed up .22lr. About six inches under the zero for my normal ammo.

As he said, a problem is that a subsonic 55 grain has about the same muzzle energy as a High velocity .22 Long Rifle. On the other hand a heavy 77 grain bullet will not give great accuracy unless the correct barrel twist is used. The Shooting Times says a 1:8 twist rate is the minimum need to stabilize a 77 grain Sierra MatchKing.

I look forward to following BlackFork’s progress.

Hat Tip: Snowflakes in Hell

CCI have renamed Quik-Shot as SHP (Segmented Hollow Point) and are now offering it as a subsonic round!

It will drive a 40 gr bullet at 1050 ft/s with 98 ft/lbs of energy! This is great news for me. I have been using Quik-Shot but since I use a suppressor subsonic is preferable.

CCI’s unique Segmented Hollow-Point (SHP) bullet is now available in 22 Win Mag and a 22 Long Rifle subsonic load. This offering is ideal for bigger targets that require a larger wound area and makes perfect sense in the 22 WMR. The flat-shooting SHP is designed to break up into three sections on impact for even more stopping power. These three segments diverge from the main path for unique terminal performance on game. The subsonic 22 LR offering is great when hunting around a populated area and a quiet, effective round is needed.
