Flash-Over incident using Hornady Hand Primer

I always use safety glasses and ear protection when priming so the thought of a single primer going off do not scare me but imagine a full tray with a hundred primers?
I have seen pictures of that and also of blown aluminum tubes and that really scares me.

That is why I quit using hand priming tools a couple of years ago.

I now use an RCBS bench priming tool with APS strips and will never go back.
It gives a much better feel and the primers are always seated all the way.
Best part is that a primer going off can never cause others to detonate.

That being said, I have a Dillon 1050 with a Mark 7 autodrive for 9mm.
It runs about 1200 rounds an hour.
Once in a while there are primers upside down or primers seated sideways and completely crushed but I have never had a primer going off.
I have deprimed hundreds of cases with live primers and never had a primer going off here either.

But Murphy is always lurking and some day it will probably happen.
We have to keep that in mind and take our precautions.
Stay safe!

Hi PaulB,
I have a Ballard Arms Model 1885 chambered for .333 Jeffery Flanged. Do you have any idea where I can get ammo for this?

I am new to this forum so I am sorry if I am doing something wrong!
Thank You!
