I reload with a Lee Hand Press. I started about 9 months ago, and just wanted to get my feet wet reloading so I went in cheap. Now I'm about ready to smash everything on my reloading bench, and I think it's a result of my equipment... but I'm not sure. I have had my bullet seating die locked at 3.400 OAL for the past 7 months or so. Tonight I go out there, put 190 gr SMK on top of 73g of RL22, and the first four lengths are: 3.312 3.321 3.309 3.308 I remeasure every round. I instantly get pissed because its a simple mechanical device, and I don't understand where there is any room for error with regards to this. I try again with new rounds. 3.318 3.318 3.316 3.327 3.327 3.319 This is all with the same press and seating die mind you. What in the blue blazes is going on here? Thanks guys.
