I don't see where range matters in reloading.
But it does influence the successful shooting system.
Sinclair offers some really good books. Among them: HANDLOADING FOR COMPETITION
There is 'Varmint Hunter' magazine, which is excellent.
And Precision Shooting released a very good 'Reloading Guide'.

Lotta good stuff out there
I started with Handloading for competition, and QuickLoad software. Never needed anything beyond that, other than personal experience.
