168 tsx minimum velocity

[the big greasy]

What is the 30 cal 168 tsx minimum opening speed. I have read down to 1500 fps for the 168 and the tsx 165 is 1800 fps. Anyone know?

Here is Barnes projectile data I've gathered over the years from phone conversations with Barnes tech support folks:

.308 TAC-TX
110gr (30321) 1350fps-Black tip (for .300 BLK)
120gr (30320) 1350fps-Black tip (for .300 BLK)
Above .300 BLK bullets will shed petals at velocities above 300 BLK the tech said on 1/6/21

.308 TTSX
130gr (30364) 1800fps
150gr (30366) 1500fps
168gr (30370) 1500fps
above numbers from Barnes tech 1/6/21

180gr TTSX is 1500fps

308 LRX

175gr LRX 1600fps
190gr LRX 1600fps
200gr LRX 1600fps
208gr LRX 1700fps

.257 TTSX
80gr 1900
100gr 1900
115gr TSX 1800

.338 LRX
250gr 1500fps

.338 TTSX
225gr 1600fps

Ok thanks, So I wonder what the 168 tsx minimum is.
