There are many commercial reloaders/manufacturers using 1050's and only 1050's. There are TWO main challenges: a) Getting range fired brass to spec & gauge checking each piece prior to loading and buying enough components in BULK to add to your profit margin.
A huge mistake is making bullets in your 1050, as you deprime/resize range brass/purchased brass. You will check these rounds only to see it won't fit the gauge, then have to use a bullet puller on 20-30% on all your work. Better is to deprime/resize all of those cases. Then gauge check the brass. If it fits, 99% of all the rounds you make will gauge check smoothly upon final inspection. Using a CasePro100 with a ponsnesswarren will ensure a lion's share of brass will gauge check before you make actual rounds with them.
