Ah, this is why I ask my silly questions! It would have never occurred to me that a tall case would be harder to eyeball on a SDB. Let's say you screw down one of your SDBs, check the powder and primers, then get to loading. How many can you realistically get loaded in an hour (while keeping an eye on things and taking no chances...kinda like a new guy would have to do)?
First, the only silly or dumb question is the one not asked.
I can load cartridges on the SDB as fast as I load them on my other progressive presses (Hornady L-N-L, RCBS Pro2000, Dillon BL550). But, I do not use a case feeder.I resize cases at and clean the cases at one time. At a later time, I prime off the press, then charge the case and seat the bullet.
It may seem counter productive in terms of production rates but it eliminates jams and other production issues that cause downtime. It makes it easier to run the process as for each phase you have less to watch and insure things are progressing properly.
Without case feeders, I load 300-400 cartridges per hour even with breaking it up into two phases not counting the time to clean the cases.
I use a Hornady powder cop die to check my powder drops on my presses that use 7/8”-14 dies. This is not an option on the SDB since it uses proprietary dies and only has four stations. Checking the powder cop die with each pull of the handle needs to part of you scan of the process.
Actually, I do most of case resizing, decapping, and mouth expanding on the Hornady L-N-L. I reloaded on a single stage press for decades so when I made the move to progressives, I already had dies for most cartridges.
I’m a tool junkie so I like to different presses. I’ve found I like different presses for different cartridges like rifle vs handgun. Mostly an idiosyncrasy on my part and all presses will load virtually all cartridges.
One last point, another poster mentioned it would be better to start with a single stage press. This is really a good idea. You learn the reloading ropes working one step at a time. Besides, if you get into reloading seriously, a single stage press is handy to have on hand. There several reloading tasks where only a single stage press will accomplish.
I hope this helps.
