Mason, there is no easy way to get good. It takes practice and time. I am still not a good shot, even after 20+ years in the shooting sports.
I coach a kid shooting club in .22, muzzleloader, archery and shotgun (shotgun not so much). There are somethings that carry over from those disciplines to airguns. The most important I believe is breathing (respitory pause) and Natural Point of Aim.
NPA refers to body alignment that supports the gun with skeletal structure, rather than on muscles flexing to hold position. Muscles get tired holding position, bones do not. That discussion leads to respitory pause topic.
We often hold our breath in while concentrating on a task. That takes muscle effort to do, and in a very short time leads to hypoxia (low blood oxygen) which further affects mental abilities (getting sight picture and holding steady.)
At the end of your exhale there is a shallow plateau where you are not breathing in or out - that is where you are most stable and using the least effort to hold still. That 2-3 seconds is where I attempt to pull the trigger. I am not always successful, but I do a lot better when I concentrate on the basic principles.
Shoot'em good
