Bowies in Texas:
I don't think they are an instant felony, like a "big" (blade longer than two inches) auto outside of a locked container or residence is here in California, but they are on the list of "baddies", which I've seen mentioned a few time.
"I offer the following only as reference and suggestion; a person's ability to legally carry any sort of knife varies greatly due location, circumstances, attitude of the individual law officer, etc. Texas Penal Code 46.01 defines "illegal knife" as having a blade over 5.5 inches, hand instrument designed to cut or stab another by being thrown, dagger, bowie knife, sword, or spear. Carrying the aforementioned is an offense; be aware that the terms "bowie", "dagger", etc. are not cleary explained in the PC. I suggest obtaining a copy of the Penal Code (university bookstores will have it) and speaking with a lawyer familiar with these sections of the code to get more info.
Hope this helps."

Why Bowies weren't thought to be included by the 5.5 inches definition, I can't imagine. I can't really comment further, but there must be some circumstances where transport/use of a large blade is legally permitted. It stuck with me because I thought it ironic considering the Alamo and all.
I think there are some forumites who can clarify this.
High powered rifles--How many do you think are good enough stalkers to bag large game with a shotgun in the desert? From a safety standpoint I can understand allowing only shotguns in densely forested areas with dwellings nearby. One of the few cases where small arms laws do make sense.
