How exactly did the priming system blow up your gun?
I have two Loadmasters and have had them for at least 15 years. Aside from replacing a few small, cheap parts (mainly consumables like the primer slider) they have worked fine for me and I'm talking 10's of 1000's of rounds. The fact is that the vast majority of problems with Loadmasters are operator based. People who complain that they don't work are often the same ones who run their lawnmower for 10 years without changing the oil or sparkplug and then when it craps out it's the machine's fault. Like any machine they have to be maintained. The priming system has to be kept scrupulously clean. Moving parts have to be properly lubed. Crud has to be periodically cleaned off. I don't consider myself especially mechanically inclined but with a little practice l have been able to consistently produce large quantities of good quality reloads on my Loadmasters.
Would I like a Dillon? Sure, who wouldn't. But for the money I saved on these two presses compared to two Dillon 650s I was able to buy two $1000+ handguns. That was a pretty good swap in my estimation. And Dillons break down too. Several of my friends have various model of Dillons and I continually hear how this part or that part broke and they had to order another one.
If you've got $1200-1400 to spend buy a Dilllon 650. But if you want a decent press for $300-400 don't be afraid to go for the Loadmaster. Watch the many videos online and things will go fine.
