No.Isn't a subsonic 223 a .22LR? Just askin'
Some is, some isn't... Virtually all of your 22 LR match ammo has a velocity of 1040 - 1085 fps, making it subsonic. Can't comment on the OP's question of subsonic .223, unfortunately..No.
22 LR is supersonic.
Those are some nice results. The 125 TNT is a great little bullet for the price.Since you asked about Titegroup, here's some loaded in a 308 w/125 tnt.
Loaded more 7.4 gr. to test. Had a zero going untill I pulled one. All 5 shots 50 yds.
Any of them would work fine for short range headshots on pests.
Anytime your loading very light loads start at the upper charge weight and work down while checking velocity, especially with jacketed bullets. You really don't want to stick one in the barrel.

The best match grade .22 (Lapua, Eley etc) is subsonic.No.
22 LR is supersonic.
I bet an adjustable gas block and opening up your gas port would solve the issue. It would be wise to have a replacement barrel on hand in case you can't adjust the gas block back to normal gas flow.I think I ran Trailboss in the past. But I lost interest in manually cycling the AR after about 10 rounds.
SSK Industries made me a Contender with a .300 Whisper & .223 barrel. I've shot both with only suppressed loads for over 30 years. I use only Unique in the .223 & WW296 in the Whisper. Both have worked fine. Accuracy is very good. Never saw a need to work with any newer powders since these do extremely well. Never had a problem with the "less than bulky" loads.
