I may be heading to the Caddo National Grasslands NE of Bonham this weekend. I'm not hunting, just camping, but will be there with others who are hunting.
As far as I can tell, that area is under joint federal ( BLM ) and state ( TPWD ) ownership / control / management.
If that's the case, I'm not aware of any TX CHL restrictions that would be in effect there, assuming it's not 30.06 posted. It would be kind of ridiculous to do that I suppose, considering all the high-powered rifles in use for hunting

Can anyone confirm?
Thanks,
Katmandu
