More Flat Primers (but with a minimum load)

[Nevada Ed]

per post #11;
Minimum loads cane be dangerous too.............
mostly in rifle loads, no matter what primer, if the volume is around 50% or less.

The primer goes off and if the load is level, it will light off the total top part
of the powder in the case..........
instead of lighting the bottom of the powder and working forward.

The large surface area can cause a Detonation faster than normal and raise
pressures in rifles and pistol loads, enough, to damage a weapon.

One reason a minimum starting load is listed with all powders as well as maximum loads.

Below starting loads and compressed loads with Ball powders can lead to big problems.
Follow the data closely.

I gave up trying to read primers for over pressure, I get flat primers using minimum loads, so I don't even consider them anymore.

...but CCI primers tend to be hard and to the point that they are harder to fully seat.
.

I am another one who no longer buys CCI primers because of the difficulty I have doing a good job seating them.

I don't know what people are using to seat their primers that say this but I use CCI exclusively & have loaded tens of thousands of them. I frequently load 200-300 rounds a week & have had no such trouble.

I give my primer pocket mouths a one-time quick chamfering & have always seated all my primers using the press mounted universal primer arm. They work without fault.

Five out of Ten reloaders surveyed on the internet, prefer different primers than the other Five do.


Some primers are thicker. not harder(which may make them seem harder)



Ten out Ten, Flat Pistol Primer threads result in the same discussion/debate.
