[Scorch]

The major steps to proper shooting can all be broken down into more detailed steps, but would need to be addressed by someone who could coach you in proper technique.
1- Properly address and mount the weapon.
2- Proper sight control (less of an issue with optical sights than irons, but still important).
3- Breath control.
4- Trigger control.
5- Follow-though.

If you can find someone to coach you in the small details, you can quickly become very proficient. If you do not get some instruction, you will struggle until someone corrects you. I assume there are still manuals in print on how to shoot a rifle. If nothing else, join a smallbore target club and get taught by their coach.
