Yeah, I plan on using a shotgun this spring. I actually thought it was against the law to use a rifle in the spring in Texas but just checked it out and it is only against the law to shoot an Eastern Turkey in the spring with a rifle. You can shoot a Rio Grande with a rifle in the spring or fall. All I have on my property is Rio Grande's.
With my shotgun I actually think 25 yards is about my max with my current setup. I patterned my shotgun last spring and was begging for my 7 mag recoil after about 8 shots with my lightweight over/under shotgun. I didn't feel it when I shot my first ever turkey from 14 yards last spring though!
