For east Texas, I would lean on 16.
There isnt a significant performance and effective range difference between 14.5 16, and 18.
We did a table on barrel length and performance based on the 123gr SST expansion threshold in the Grendel Handbooks that breaks it all down, with a velocity range for each barrel length.
10.5 260yds
14.5 350-400yds
16 400-420yds
18 410-440yds
20 450-490yds
24 500-520yds
Will you be shooting suppressed? If so, I would look at 13.9-14.7 with a pinned and welded brake attack muzzle device for the suppressor to bring it to 16, that way you can have a short, compact fire stick without dealing with unconstitutional NFA horse crap.
