Me too
Ok, So I was in the same boat as you kind of sort of.
I grew up hunting and fishing all my life. Only thing I truly know how to do competently is shoot. Can not please any employer for my life, but I know how to shoot. Now comes today, why not try to shoot better, maybe even try competitively. After weeks if not months of reading several forums like this one, I finally spent some money on a few books. I can not give the names as right now I am not at home, but anyways, it was a start. As of right now I have purchased a nice heavy front rest(hart or heart), a rear bag the one with the ears that you can add and remove sand, I removed the sling attachments from the bottom of my rifle. I load 3 sets of 5 shot groups in different powders using same bullet weight. I document everything!!!! I can not express this enough. Document everything. I write all the load information on the target and then at the end of the day, once home, I cut the target up and glue the groups on binder paper and keep in a binder. All the information is with the target with the group. Do not worry about where the group is on the target, concentrate on posture of body relation to rifle during firing and concentrate on repeating everything exactly the same during the shooting. Now this is of course once you figure out your shooting style. Some shooter hug the rifle, some only touch the rifle trigger with one finger and that is it. I have seen people fire the rifle using a trigger weight gauge and document this too. It is different every shot believe it or not. not by much, but it will never be the same. There you go, that is a start. Once you become part of your rifle, add a little more information to your trigger time. it all comes together nicely after a while and you will be eventually getting people asking you questions or asking for advice.
