1050 doesn't have a lifetime warranty, so when the 1050 got worn, I put a zero lash pin press bearing in it. One of my 650s got a bronze bushing with lubrication grooves, not enough frame for a press bearing.
Greatly extends the life of the presses.
The 1050 has about a million rounds and still VERY tight.
It's the difference between consumer grade & industral grade.
I know why Dillon doesn't use roller press bearings, they intended their machines to be hand powered, I drive them faster & longer than Dillon ever intended.
I've actually reproduced a heavier version of the 1050 frame so I can use even better bearings, just haven't had the time to complete it, but I'm hoping to complete that now things in the shop have slowed down a little...
Dillon has to deal with cost/benefit and not so educated users/abusers, and I get that...
Not every friction surface needs to have roller bearings when hand operated a 1,000 rounds a month, when you do 1,500 cases an hour, all day long every day, it's a different story...
Dillon does a very good job, a good balance between 'China' parts, quality American parts, application vs cost. The design works, the parts fit, the machine holds adjustment simply because friction/wear is kept to a minimum...
I can't even imagine how much a 650 would cost if the plastic parts were machined steel and hardened against wear, roller bearings were installed at friction points, etc.
It's basically a weekend reloader machine that's just not going to be used in seriously high volume work, so what they use saves a crap load of time & money, and with the 650 replacement parts are free and Dillon doesn't crank about living up to the warranty...
My bench rifle ammo is still cranked out on a single, iron frame press.
My match ammo is cranked out on my rebuilt 1050. I have no complaints.
My brass for the match shooter is cranked out on a rebuilt 1050, and they do win matches.
I don't load them, but I do beat the cases back into shape so they have a top notch product to start with.
Every match shooter has their favorite load, so cranking out loaded ammo is pointless (the money is in the brass anyway, no small repop shop has a chance to compete with commercial manufacturers.
As for 'Electro-Mechanical', yup, count me in.
Nothing like taking human error and having everything double checked, and very much volume at all and the QC inspection will eat up as much time as the actual processing & loading.
Don't forget, match shooters are the most demanding customers you will ever have.
Bench rifle shooters don't buy enough reconditioned brass to talk about, but match shooters are ALWAYS practicing or competing, so they go through brass like crazy, and they aren't snobs, if once (or more) fired brass can be made to run with factory ammo, they will jump on the cost savings/availability.
It's up to you what you do, most home loaders don't roll cases, they don't anneal in volume, they don't uniform & deburr flash holes, etc. Just cranking rounds directly out of a progressive is going to give them a more consistent case/load than they/their firearms have the ability to detect the difference.
Not so with match shooters... So if you can crank out match quality rounds, no reason to shoot for plinking quality rounds, take advantage of the accuracy the machine provides.
