My F-I-L has 2 1050's, But I don't remember if they are "super" or not. If you are reloading in the "Many thousands" (I put that at over 75,000) a year class, I don't think you can beat a 1050. I have been in the "less than 40,000 a year" class for 28 of the last 30 years and found a 550b to be enough press! When we set up the 1050's, we were doing test batches to figure out the best rythem and routine for large production batches (100,000 or more). With two 1050's going, we found 3 people the best system and 2 people for one machine. For the one machine setup we worked in "1/2 hour" shifts (actually 500 round shifts). One person ran the crank and seated the bullets, the other person filled primer tubes, and kept the components filled (bullet tray, powder and case hopper) we referred to this a the support position. The support person had free time to go to the bathroom, get a cup of coffee and still support the loader very easily. After 5 tubes of primers we would trade positions. We could continue this for as long as needed. On 10 hour days we had a 30 to 45 minute lunch break in the middle of the day. Our set up was standing the entire time. A friend had an original Dillon 1000 set up to sit on a bar stool, he had 15 primer tubes and would go until the were all empty and take a break the fill up everything and replenish "at hand" powder, bullets and cases then do another session.
You do not have to have an expensive tool head ($125) for each cartridge change. You can change out dies, just like any press (the shell plate is the time taker! on a 1050) Look at a complete change at taking about 1 hour, once you know what you are doing. Enjoy! Ivan
