Dillon's new XL750

The reason for blow ups is bad design. It you can manage to blow up a primer on the 550 only one will blow, not the entire tube mag.
Primers can be totally mangled and if there is no shock involved they will not blow. Put a primer in a vice and slowly crush it (always assume it will blow for safety). As for arrogant I call them like I see them. I am not a Dillonite
But I do have 2 Dillon presses. The one that blew was brand new and spotless. The issue is not a single blowen primer, the issue is that if you do blow one it will take every primer in the press with it.

Hang on here... are you saying the 550 doesn't use a tube full of primers? I don't have a 550 but I do have a 650 and a 1050. They both use a mechanism where the primer drops into a hole on a carrier and is transported to the priming station on the press. The 650 uses a circular carrier and the 1050 uses a linear but they both move the primer away from the tube (obviously) to line it up under the shell plate. The only way a primer will go bang and ignite the tube is if it doesn't fall flush into the opening on the carrier.

I'd love for an explanation on how the exact same gravity fed process on a 650 is inherently more dangerous that the 1050 or 550. If you blew a primer that took the tube with it on a 650 you either had dirt on/in the primer carrier, you had a misalignment of the primer magazine and the carrier causing a primer to drop into the carrier sideways or you didn't have enough pressure to drop the primer into the carrier.

Either way you look at it, the physics of how pretty much all Dillon primer systems is the same and if you blew up a tube you did something wrong.
 
FWIW I have had 2 primers go off in my 1050 but they were both cases with live primers and went bang in the sizing/decapping station as the primer was being pushed out. Wasn't that loud when it's all contained in a die.
 
I have had my 650 primers explode on one of my 650's. All of them go off (60 were in the tube). Makes a loud bang, a lot of smoke, a lot of little holes in my ceiling, the plastic rod is sticking in the ceiling as well. Oh yeah, I forgot, a very pissed off wife.
Dillon will replace the entire primer system under warranty. I asked if I could re-use the base and black tube, but Dillon said they are only good for one explosion.
This does happen, Dillon will admit it. I was using CCI primers, in which explosions are rare. Dillon says it is usually Federal primers that cause the explosion and in the instructions it states not to use Federal.
I own 2 x 650's and 1 x 550. I have a Mark 7 Autodrive on one of the 650's. It has only happened once to me. I am extremely more careful now and have slowed down a bit. I also maintain my presses to a higher degree now.

Where were they when they went off? At the bottom of the primer mag or under/in the case they were destined for?

Hi Corey,

They were in the case at the bottom of the priming stoke. I was trying to seat them a little too deep for revolver.

Oddly they were still too hard for a 929 and I gave up on that experiment. They shot super clean however.

I clean my priming tubes on a regular basis. A small wad of paper towel soaking in brake clean pushed through by the plastic priming rod. easy

Ya... this is the only place they will go bang unless it's operator error in that either large primer pieces are still on the feed mechanism or the feed mechanism is dirty. There is nothing to "punch" a primer until it gets to the die station so the only way a primer can go off even close to the primer magazine is if it's sideways or not fully in the rotating disk. Both of these issues will happen regardless of the priming system. Some people think it's unique to the 650 but they are idiots.

Explain how it can happen then.

Because you screwed up you are blaming the 650 priming system.
