.223 Barnes load

I haven't used TTSX but for most 55gn bullets I use Vhit n135 24-5gns to about 26gns You could start 10x at 24gn and go up and check groupings etc , good luck
 
I would urge caution and stick with recognized load data from Barnes or the powder manufacturers.
 
just loaded up some 53gr Barnes over n133
23.2gr in a .222
two clear nodes at 22.2 and 23.2 seated to -50 thou OAL
