I use the Redding competition die for bullet seating on a Dillon 650. I set it for 1.100, and will get ranges from 1.100 to 1.250.

They all gauge and shoot fine enough. Is that an acceptable margin for range ammo?

EDIT TO ADD: that I am a dumbass. 1.100-1.125 variation.

It's not dangerous or anything like that, but that's a huge variation.

Kind of looks like the seater plug is the wrong one for the bullets you're using or the bullets are really cheaply made.
