precision rifle

To do what you want and be good at it is like learning to skydive by starting off BASE jumping.
Reloading cheap safe rounds is easy but loading highly accurate rounds for load developement could be taxing.
What you need to remember is make every step and component the same.
Trim all casings the same length. weigh all powder loads the same. seat all primers with the same pressure(tricky). seat all bullets to the same depth. weigh brass and bullets culling those to heavy or light. turn casenecks to the same thickness.
Then there is the small stuff like deburing the flashholes, chamfering the throat and uniforming the primer pockets.
Then you are gonna want to seat the bullet just off the lands of the rifle.
this will get you to the first round you test.
Now try diffent primers to find which have the least standard deviation in the velocity. then move up and down in powder weight until you groups stop getting smaller and begin to open up. then move the bullet deeper into casing and see if the groups get larger or smaller.
At this point, pick another powder and start over again.
And don't forget to start all if you change lots of powder or brass.
