After reloading during the rain on Sunday I finally had the time to crank out some rounds. Being a cautious newbie I ended up measuring OAL on several of those completed rounds. I had some concerning numbers ranging from 1.121 to 1.130. I was shooting for 1.125 per several sources. Does anyone have any advice as to why this number is changing so much? My bench needs more support (in the process) as I think perhaps it was jarring the press slightly. It is a Dillon RL550B with Lee deluxe carbide dies w/ Dillon lock rings. Any advice would be greatly appreciated!
