SUBSONIC .308 WIN reload data

[NWARvet]

I am looking at reloading some .308 WIN subsonic ammo, but I feel like it's kinda hard to find the data. Any help would be greatly appreciated.
I am looking at the Hornady 190gr .30 cal SUB-X bullets, Trail Boss powder. normal brass and normal large rifle primer. Can anybody chime in? I'd love to learn something new today, lol.

Don’t forget the 175 SubX.

Depending on your twist rate, those might not work. My Tikka CTR is a 11 twist and the 190 sub x were key holing. I had to go to a Hornady 170 flat points. These are shorter that the 190's but still 170g. They shoot very well 10g of Trailboss.

This was why I offered the. option of the Hornady 175 SubX and data.

I loaded some those 190s in a 10 twist Ruger American with Titegroup powder and shot less than 1” groups at 100 yards at like 1040 fps.
I could not find any TB

Just like Eric same gun but I used h322 powder. Right at 1050 and about a inch at 100. Killed a tom and the 1s with him didnt do nothing but walk around. Worked good...and we can hunt turkeys in Va with a rifle...it was with the 190s sub-x
