honestly it's average shooting. i dont want to discourage you, or try to down you. but i remember when i first started out, or even now sometimes. people will say im doing a great job even when it sucks. i guess their giving an A for effort.
i think to be honest with you is the best policy. not to say you're not doing well, but to say you can do a whole lot better.
you said 20-30 feet? thats not very far. i am assuming you was shooting off hand (standing without rest). there is a lot that can be done to improve your groups just by taking the empty gun and practicing your sight alignment, grip, stance, and trigger control at home.
if you dont do it already, take the unloaded gun, stand as you would on the range and act as if you're going to shoot it. hold the gun the same each time, breath easy, squeeze the trigger while concentrating on holding the sights aligned on a speck on the wall, and pull the trigger. practicing your stance and grip, making sure they are the same each time and practicing trigger control will help you a bunch. do it every single day if you can, even if for only 3 minutes.
most people cant hit the broad side of a barn. im not a great shot. but i am far better then most people at any distance.
i think that if you dont already have a proper grip and decent stance that learning a new technique will help you out tremendously. and make sure you dont press the trigger with the joint of your finger. you should press it with the center of the pad of your finger, halfway between the tip and the joint.
last time i shot my single six on paper. i was sighting it in after knocking the rear sight off. 25 yards i did about a 2" group off hand. to do a 1" group at that distance. could be that the cheap federal ammo isnt consistent. could be i was just having an off day.
theres nothing wrong with shooting fast. shooting is a lot of fun and it looks like you're having your share. i dont want to discourage you and ive tried to choose my words carefully. i want to encourage you to get better.
if you was handy i would suggest we go shooting together. mostly cause i need all the shooting buddies i can get.
