Has anyone tried writing on cases with magic markers when doing load development?
Charge weight primer etc.
Will it hurt the brass? I sure can't see how it will hurt the gun/chamber.
Hope this question isn't showing too much of my ignorance.
Thanks Shawn Allen

I do it all the time. Beats ruining a range session after you spill your reloads and don't know which is which. I remove the writing for the next reload with a bit of Kroil on a rag. Comes right off.

I have done it for years.
Doesn't seem to hurt anything.

Thanks fellas.

I write on the bullet. That way I don't have the hassle of cleaning ink off the cases.

I do it all the time with pistol cartridges for incremental overloads to see what happens. I use a Sharpie indelable ink felt pen.

Some one gave me a 303 cartridge with a 1909 headstamp, but they wrote "1909" in huge numerals on the case before handing it to me. I think that screwed up the collector value

Sharpie makes an "Ultra Fine Point" permanent marker that is perfect for writing on bullets (better than the case because you don't have to clean it off). Nice thing is it won't rub off...

I color code the primers or the heads with different color markers then make up a list of colors to load info. Don't have to clean the brass after the range session.

I have a set of small rubber "primer" stamps, 0-9. Forget where I got them though.

One thought about writing on cases rather than on the bullet, with the case marked you can measure the case head expansion and check for other signs of pressure of the various loads back at your reloading bench and know which load went with which case.

Anyway, I have done it both ways, on the bullet and on the case. Great way to seperate loads.

Bob338...You stole my post!!
I started writing on cases, after one such spill...sakofan..
I also like to be able to knock the bullet out, and save the powder charge on a bum load, and know which powder I used.

I use a Sharpee pen and number the case corresponding to the load as noted in my notebook.
Simple, number stays on, although a bit faded after firing, probably from the heat. Number is placed on the case and the primer.

I use a Sharpie or any other indelible marker for that matter. I roll my finished loads
for run out, and mark them at the high spot, near the case head. Works like a
charm. Best wishes.

Geez, if you go to a highpower or IPSC match, you'll see more written-on brass than you'd ever believe. And the whole spectrum of colors too!

Redial, I know where your coming from with the IPSC shooters and their colors. I use different colors to mark the heads of cases to ID same cartridge loads I use in different rifles, red for one rifle, black for another. I stops me from trying to put a neck sized case from my M700 in my M7 ect, and helps separate them at the bench.

I also use a sharpy. I like to put some sort of abreviation for the powder type, U for unique, 110 for H-110, red for red dot, etc, and then either the charge weight or powder scale setting, depending on which I used.

I usually shoot a day or two after I load up ammo, which is why occassionally I don't lable ammo, but then again, I've had ammo I thought I'd shoot in a day two that didn't get shot for several months, just long enough to forget what that load was.

Use a sharpie!
