4 and a half stars. I have run about a thousand primers through mine so far and 99% of the time it runs great with zero problems. I have had 3 or 4 primers make their way into the tubes upside down. I caught one of them but a couple got by and were loaded upside down. If they make a large primer conversion I would buy it and I do not regret purchasing this one.

I have used these for our commercial loading setup. We use rubbing alcohol to wipe off the back of Winchester primers (before removing from packaging tray) wait 20 seconds for them to dry then put them in the Primer-pro. I also use silicone spray on a q-tip then wipe the feel channel so they slid easily. We have 4 of these in use and have well over 100K primers through each of them. we will completely disassemble the collator and clean it once a month and they work without issue.

At first I hesitated because of the price point. I reminded myself of just how much I find little enjoyment in loading primer feed tubes or APS strips. With a Primal Rights CPS installed on my bench I quickly got over the sticker shock of this item. Spent the time preparing the plastic parts, setting the magnetic collars and it was off to the races. After charging a couple thousand Federal & Winchester primers I find this accessory a welcome addition to my toys.

If you have a lathe, then a minute of parting, contouring and deburring McJ Tools Pick-Up Tubes (available on Amazon) gives you an inexpensive supply of primer feed tubes for your CPS

Nice tool, but takes a lot of adjusting. Took me a couple if weeks and then it works, however, you have to stick to one brand of primers. Take a different brand and you can start over again with adjusting... also you have to lubricate it with graphite for smooth operation

It's not as fast as I imagined it would be, but still nice not to have to load primers in the tubes by hand.

This is second review. Let's see if it makes the website. The product itself is poorly constructed, all plastic, and has multiple choke points. Metal screws in plastic that need constant adjustment will lead to wear and the screws nolonger functioning. The hole the the primers fall into the tube routinely has primers that get stuck even though you realign and adjust the collar. Primers feed,then don't feed, then feed with no rhyme or reason.

The 2 stars vs negative stars is for the customer service. They are fantastic. Very helpful, understanding, knowledgeable, and polite.

Great people poor product.

Dear Shawn,
We must disagree that this product is “poorly constructed” because it is made from plastic. It was engineered to be made from plastics, and could not easily be manufactured with any other process other than injection molding with its current design. The materials uses are all high-grade plastics and nylons and are not “cheap” by any means. There are no screws needing constant adjustment either.
I am sorry to read you are finding the Primer Pro finicky to use. most users (over 5,000 of these units are out there being used now) are happy with its performance. Not knowing the details of the issues you have experienced its hard for me to respond in detail. but certainly primers jamming on the way out of the exit hole often has to do with the primer tube in use and its chamfer. Try to run the primer Pro without a tube, dropping the primers into a cup to confirm the exit hole is good. Then, QC the edge of your primer tube hole and symmetry of it.
Depending on the type of primers in use, follow the online advice regarding cleaning/polishing the surfaces of the primer bowl to prevent the tacky primers from sticking to the that surface.
