Couple tips I do to help me with accuracy on paper.
1. A lot of ammo. Practice, practice, practice.
2. Know everything about your trigger. The pre-travel, the pressure it takes to break, know when it breaks, take it out for dinner and a movie....whatever it takes for you to learn your trigger.
3. If bringing rifle from air conditioned home to warm weather outside, let gun stabilize to new temperature for at least 30 minutes.
4. Keep your heartbeat soft and steady. Basically don't run 100 yards like a little school girl to your target stand, run back to your gun, and start letting pellets fly!
5. Solid shooting table.
6. Kind of related to heartbeat...don't grip the snot out of your rifle. Keep soft even cheek weld, shoulder, and grip pressure on your gun. Heartbeat can really be distracting when trying to hold your cross hairs on the target.
7. Last ,but not least, know everything about your rifle. You should never have to think when you want to manipulate your rifle. You need to build that muscle memory.
Anyways these are some things I have applied to building my skill as a shooter.
