I have looked up Texas laws re: using my Garande. As long as I use a 5 round clip and not the standard 8, it is legal to use it on deer. Hog hunting is a little less regulated but don't push your luck there.
From TPWD website........
Magazine Capacity (number of shells/cartridges allowed): There are no restrictions on the number of shells or cartridges a legal firearm may hold when hunting game animals or game birds (except migratory game birds, see Legal Shotgun).
