I have been loading for a while with a single stage press. Just recently I purchased a progressive press with the hopes of speeding up the process considering I have started shooting weekly. I have been reloading .223, .308, .357 sig, and 9mm. My question is toward 223 loading. I have noticed that when sizing and de-priming my cases (mostly LC and Remington brass) it is not very smooth on the up stroke as well as the down stroke. I am using RCBS FL sizing die and I have used a Hornady sizing die with the same outcome. I am using Hornady one shot lube and I have also used RSBS case lube. I have watched several videos on loading on a progressive press and all the videos seem to run very smooth compared to what I am doing. Any suggestions on how to fix this issure or is it just the way it is?
