I just finished extensive research on this issue, and in so doing, have set a new worlds speed record for loading 100 quality 357 magnums on a single stage press. The procedures involved include:
Selecting 100 brass cases
Measuring 100 cases.
Tumbling 100 cases. Includes changing the media in the tumbler.
Full length sizing all 100 cases.
Re-measuring all 100 cases.
Trimming all 100 cases on a Lyman Power Trimmer.
Deburring 100 cases, outside only.
Checking the primer pockets for uniformity in 100 cases.
Deburring the flash hole in 100 cases.
Flaring the case mouths of 100 cases. includes searching for the case flaring die I haven't used in 10 years.
Cleaning surface rust from the case flaring die & oiling it.
Removing the oil from the case flaring die (oops!)
Tumbling 100 cases again, with polish to remove my paw prints
Cleaning tumbling media from the flash holes in 100 cases.
Priming 100 cases with my RCBS hand primer thingie.
Selecting 100 140 gr Hornady bullets from my stock.
Researching & selecting suitable reloading data.
Locating my old Hornady powder measure & changing the drum over to the proper style.
Setting up the Hornady measure & calibrating my equally elderly Hornady powder scale.
Charging 100 fully prepped cases with AA#9.
Changing over to my bullet seating die & adjusting said die.
Seating 100 140 Gr Hornady bullets in the prepped, charged cases- no crimp applied.
Change die to a Redding Profile Crimp Die, and adjust.
Crimp 100 loaded 357 magnum cartridges.
Search for an unused 100 round MTM box for my treasure.
Inspect & box 100 loaded 357 magnum cartridges, and label the box.
I accomplished this simple series of tasks in a blistering 4-1/2 days, pausing only to eat, sleep, work 10 hours a day for two of those days, go to the store, watch television, and talk with the neighbor a bit. And go to the gun store. I'm confident this new worlds record will stand for a long time. I have enclosed the manufacturers name for my major reloading tools, since I know there could be a major sponsorship offered at any moment.
