I haven't purchased caliber change overs for this press yet, but i wanted an idea of about how long it takes to do a change over. To satisfy my curiosity i took the press apart and put it back together. I discovered that complete caliber change including different primer size is about five minutes. I also realized how simple in design and function the press actually is.
If the case feeder were to require adjusting, it would add probably another five or more minutes. I set this press up originally without using the instructions. I referenced them for final case slider adjustments. When i took it apart and put it back together, i watched the videos from the above link and fully read the instructions, and i set up the case feeder according to the instructions.
I discovered that my adjustments for the feeder were incorrect, yet all the ammo i had loaded on it, the cases all fed just fine the way i had it. Using the instructions and the videos required the feed bracket to be turned out of the press an additional three full turns! I am just going to leave it the way it is for now, but the next time i take it down for cleaning, i am going to adjust it the way i had it before.
