Thread: Perfecting reloads - what to do first?

I'm reloading for my new 7mm08. I've made my own before but this is with a much better rifle now.

I want to get them just so and know I need to figure out the best charge, the best projectile and the best length of the round for the barrel.

My question is what takes precedence. Get the charge right - so it's giving pretty consistent velocity and accuracy before I worry about how close to the lands I am? Or will changing the length undo the good work with the charge?
