Accuracy is a complicated event and I think it is important to figure out what affects accuracy the most. When I think about accuracy, here is what I think is most important to least important.
1.) The quality of the shooter.
2.) The quality of the gun.
3.) The quality of the ammo.
4.) The cartridge selected.
Notes: Great shooters can shoot most any gun well. Poor shooters will never shoot even the best guns well.
I put cartridge as least important because there is so much variation in the first 3 items that most shooters will never get to the point where what you picked as a cartridge will make that big of a difference.
Thoughts? What am I missing?
