Deff something you'll get a million opinions on, lot of caliber and projectile length based I/we dont shoot under 300yrds for because of this on the 338lms often will actually shoot tighter groups at 400yards than 200yards. goes completely against conventional wisdom but have proven it countless times in lots and lots of testing. other calibers vary on this obviously but you also need some distance to really see into the specific variables and be able to scientifically break them down in to why its doing this and that.
Here is what I do.
Ladder testing: 400-600
Charge weight testing: 100 (course) & 200 (fine)
Seating depth testing: 200-300
Load verification: 500-1200+
