Well like a lot of things, it is generally the USER, NOT THE PRODUCT, that is the problem when things go horribly, catastrophically wrong. Like the guy in the ammo factory in WWII who carried primers in a bucket from one place to another (yes, really). He would shake the bucket to hear the primers jingle and one day there was a huge BOOM! Reportedly all they found were his shoes and red painted walls. seems the primer compound was being shaken out and finally went off, no more carrying primers in buckets!
Yes, the 550 CAN have the primers blow in the tube (thank God not to me!) but that is why Dillon put the heavy tube in another steel tube, just in case, so everything goes up. Also the Lee presses CAN have primers blow up in the primer feeder (the primer feeders in Lee presses are junk in my experience but that is another post) and if you use the recommended primers (Federal and others, NOT Winchester) when (not if) they blow they usually are contained, but it is aimed right at your face. Winchester MIGHT blow the feeders up, so Lee sells a shield rather than up grade the feeders and then attacks Dillon in the MODERN RELOADING to make himself look bigger, exactly as happens to me when I am attacked. Of course if you can't find at least 32 lies about the Lee warranty in the book and a few dozen others (yes, it IS a great read about reloading IF you understand most of the stuff about Lee being the best and the so called warranty is an out right lie) and some other mistakes, you aren't trying. If you have ever talked to Dick Lee you know what I am talking about. Rather than upgrade the Lee equipment to make it better, Dick attacks every other reloading manufacturer for upgrade THEIR equipment to make THEIR stuff better!
