Product Description

Install on your progressive press after the powder drop station to automatically check dropped charges. Checking powder charges on your progressive press can be difficult, and is sometimes ignored, even though it's a smart practice. Hornady uses a similar device on our own ammo manufacturing presses. It won't replace careful attention, but helps monitor the reloading process. Works with all powder types and cartridges

This die isn't just nice to have, it's great to have.

It checks powder with a rod. This rod drop into the case and indexes a little white O-ring at the top of the rod above the die body. You observe the position of this O-ring, and if it doesn't come to the same height each time, you know there is a different volume of powder in the case. An undercharge shows up as a lower O-ring. An overcharge will have the O-ring well above where you've decided to index it. That's all there is to it.

The die needs to be degreased with alcohol, or something similar, prior to use, so that no powder kernels will stick to it. Use a dryer sheet to take any static out of the inside of the die body and the rod.

The die, and component parts, are well made out of ferrous steel. You'll need to do the same rust prevention you do on your other dies/steel tools; whatever that may be.

Currently there are three similar dies that do Powder checking. This die, the RCBS equivalent (which may be even easier to set up) and one that locks the press when it detects an over or under charge.

What's good about this die is that you can see how much powder is in the case, whether it be over, under or correctly charged. Very handy to double check how well your powder measure is throwing. It's much easier than peeking into the case. So much so, in fact, that's it's definitely worth the price of the die.

I'd recommend this die, or similar one, for those reloaders that have the space on their press, progressive or turret, and like to be squared away in their reloading procedure.

If you want to fiddle around with a die, you can probably modify a Lee Universal decapping die to perform powder check functions. Of course, it may or may not work out for you, and it won't be ready right out of the box. However, if you reload a lot of different calibers, the price differential may make this approach viable.

As a relative newbie to reloading, I wanted to make sure, as my wife put it, that I didn't "blow my face off". Apparently she values my face. The Powder Cop, once properly set up, makes sure my face stays intact. The rod will either show an overcharge (rod goes waaay up), an undercharge (no white ring), or no charge (no movement of the rod at all). If you just keep your eye on the white ring, everything should be fine.

The neat part about the Powder Cop is that, unlike the RCBS Lock-Out die, it'll work with both pistol and rifle cartridges.

The not-so-neat part about the Power Cop is the accumulation of powder on the rod, which will inevitably fall onto your shellplate, get under the shellplate, and cause minor timing issues. Be sure to grab some compressed air and clean out the area under your shellplate (at least on the Lock-n-Load press).

"It won't replace careful attention, but helps monitor the reloading process. Works with all powder types and cartridges"

It does not provide an accurate powder measurement but rather, it provides a visual for powder dropped in the cartridge. This will be a nice compliment to your progressive reloading station. To me, it seems redundant if you have a single stage reloading station. This powder cop will definitely indicate whether you are short on powder or have too much powder, however. It should not be a replacement for common sense and proper reloading checks that every responsible reloader should take. I'm happy with it. It just gives that little extra peace of mind.

I found the powder cop easy to set up even with the very limited instructions that came with it. It should be a standard item on this press and not an option. I had loaded about 70 rounds and then no powder in a case. With out this item I would have seated a bullet in a empty case. I will not load on the progessive without it.

I just got into reloading .308 for my AR style rifle. setting and dropping the right loads in the cases took some effort to properly dial in the powder drop. Some charges were inconsistant. With this die I am able to quickly and conveniently access the powder levels without removing the case and looking into or wieghing the powder. Its a great addition to an AP when loading tall rifle cases. I dont regret spending the money on this. First time reloader, Hornady has made it very easy to start up this rewarding hobby.

It could be built more like the lock out die from RCBS. This one you have to watch every time you throw a load, the lock out die does that job. It's OK because I don't want to go too fast, I wait a bit at the top of the stroke for the powder measure to completely empty. That's where I've gotten use to checking this die. It is accurate, just a bit more work than the lock out die.

Just like the heading says, I wish these were standard equipment on progressive presses, not much to talk about here, other than to say this thing does EXACTLY what it says it will do. I'd buy it again.

i check, recheck, and recheck multiple times prior to new loading sessions on the powder drops, then i weigh each cartridge when i complete 50 rounds or so.

call me paranoid, but i do not wish to have anything blow up in my face. this device gives me an extra reassurance that i do not double or squib charge.

i have the hornady powder cop b/c i load 223, the RCBS is only for pistols and the dillon requires massive modifications to fit on anything other than... dillon

i grade it an "A," not quite the A+ like i would rate the RCBS lock out die or dillon with it's loud audbile tone indicator.
