bigger plunger for Hornady powder cop die?

[BunnMan]

I routinely use the Hornady powder cop die to check charges before seating on my LNL progressive and when doing small diameter cases (9mm and 223) I can pick up even slight deviations in charges, like a couple tenths of a grain. Doing larger diameter stuff i think the plunger sinks in the powder sometimes. It just doesn't seem to be near as precise. I know charges are to be checked by weight and not volume but it is a handy indicator and does prove out failry accurate when it makes me suspicious and I doublecheck the suspect charge on the scale. With the small diameter stuff anyway. Anybody figured a trick for a wider plunger? I'm thinking maybe a plastic cap or something but it would hae to be BRIGHT so I could see it if it fell off in a case...lol

Thanks,

Drill and tap the large end for a very small screw and attach a colored plastic disk to the bottom. This way you can remove it vs gluing it on. You ARE using the large end for larger diameter cartridges of course?

It only appears to have one "end" which would be the larger end. I guess you ciuld flip it over but it would look upside down with the rings on the bottom and the plunger on top. In that case even the "larger" end fits down the neck of a 223 case. I dig the drill and tap idea...I'm going there.
