In my experience(not much more than yours) if you're using the best ammo(Eley, Lapua, RWS etc.) weighing and sorting will not be worth the time and effort. JMHO-Barry
The best teacher is getting out and shooting. When you start shooting your matches you will see what the winners are doing and I would be pretty sure they would be willing to help you in any way they can. Experience is a good teacher. Barry
I have a 6-24 4200. It is a great, clear scope but they are known for having very limited adjustment. I have used the Burris inserts to get it centered and on target. Barry
