I have never personally seen this happen or seen the aftermath of it happening. I would like to know if this is a common issue with all reloading equipment or if it is only one or two specific brands of equipment. I did a quick search and I found Dillon and Lee as the culprits but I am not sure if they are the only ones that are capable of doing this. I will say this much I have a first generation RCBS ammo Master Progressive and I have had this press since it first came out in the late 80s. Never had a problem with it I know what a primer should feel like when your seating it and anytime that I run into problems I Don’t Force It I stop and check to see what the problem is. Often times I find that I’ve missed a military case that did not get the crimp removed from the primer pocket and had I just forced it in I am sure they would have went off however I do not think it would have created a chain reaction on my particular Pres based on the way it is designed to work so I would like to know if this is a poor engineering issue and from the way I saw one YouTube video on Lee I would definitely say it’s a poor engineering issue so what brands does this happen on

Finding this took all of 10 seconds. In the search results are several mentions that I did not look at, and one video that I did. Take a look.

I just bought some tubes and they came with the recommendation that they regularly be washed out with soap and hot water – which I plan on doing with each use. The time spent is worth it to me.

Exactly.

The primer tube on a Dillon machine is
double walled to contain an explosion like that.

While the press-mounted APS tool is no longer produced, RCBS does offer a bench-mounted version – http://rcbs.com/Products/Priming/Tools/APS-Bench-Mounted-Priming-Tool.aspx If you have the bench space, this both saves your hands and avoids the steps of swapping dies and the tool back and forth in your press. For those that like a dedicated station for each step in the reloading process, this works great.

Some time ago, I figured out that the three most important issues for progressive presses are primer feed, primer feed, and primer feed. If reliable priming is achieved by a design, all of the other issues are relatively easy to deal with. Having said that, the reason that the editor gave the recommendation that he did was not because it is an infomercial, he was telling you of his personal experience with various priming systems and about one that has worked particularly well for him, and which by design prevents the problem shown in the lead picture for the article. I believe that this sort of information is some of the most valuable that is available on the internet.

I am for the wear of safety glass when ever required but reading the article with the Brand name dropping looked a lot like an “info-mercial”.

Excellent reminder. Equipment never gives notice of when a problems of this type are about to occur, so measures need to be put in place to either keep them from happening or prevent injury if they do. How many of you reload without eye protection, or for that matter shoot without it?
