Practice Makes Skills

I find that people seem to think that unlimited time on the range will make them the best shooter ever. This is not necessary the case. You have to build up to it. I have the advantage of having a place to shoot on my property, and this allows me to be able to shoot whenever I want to, so naturally I get alot of trigger time out of it.
My advice to you as a shooter is to not overdo it at the range. If you don't understand why, lit is simply because it can reinforce bad habits. So be careful about what you are doing, and establish checks throughout your training and practice to ensure that your skills are in check and your trigger finger is still in the game for you. Things like doing slow fire at range at the beginning of your range session and periodically throughout, is a hugely beneficial method of spotting dysfunction before it messes with your progress and potentially reversing it.
I have a saying about all this. Dry fire to train, and use live fire to confirm progress. This has paid off for me in many ways, and it is important to be able to see when you need to quit. Shooting fast is like working out. You are putting alot of demand on your one finger to independently push a button in an odd manner fast, and without using any other muscle for support or assistance. This is not necessarily how the hand is supposed to function, but that is the great thing about being human. Our bodies are very adaptable and flexible. Just remember that your trigger finger is not a bicep, and a low weight/high rep workout is what shooting is to your trigger finger.
Keep these few things in mind, and I am sure you will always see positive advancements in your skills.
