I switch back and forth between calibers on my LnL. Its not that bad. Takes me 15 minutes at most, and that only going from small to large primers or vice versa. The secret is having all the tools and parts ready on the bench before you start.
Generally my LnL is set for small primers as I bulk load 9mm and 223. Change over for those is minor. Swap the rotor and change the bushing in the drop, and adjust on an empty case, takes a couple minutes, 5 at most. Change the bushing in my case feeder and adjust and swap the feed plate, 1 minute. Change the shell plate, 1 minute. Thats about it, less than 10 minutes.
Going from small large primers takes about another 5 minutes to swap the primer punch, primer slide, pusher foot on the case feeder.
If you dont have a case feeder, this process takes less time.
