I picked up a Loadmaster and after watching all the vid's I could find in tweaking this,filing that watch for this and don't do that I'm up and running.
It's the REALLY S****Y instruction's included with it that cause problem's.
I decap,size,prime,flare,charge,seat and use the factory crimp die.
All this for 45Win Mag, a caliber I bought this press for exclusively.
I've had some boo boo's but took it slow, ran it without anything in it at all to see how it work's and generally got familiar with it.
When it came time to load up I did one case at a time for awhile till I got familiar with it.
When i put the case feeder on it same thing,look-learn-listen.
I've picked up spare part's,just in case and have crunched a primer slider/feeder.
It's a learning curve with this press, a LOT happen's with EVERY up and downstroke.
Run it empty and LOOK. Wear it in a bit DRY, high spot's show themselve's and can then be taken care of.
You wouldn't drive in a big city the first day you learned to drive a Standard would you?
