Does anyone have any experience with the RCBS Chargemaster Combo Powder Dispenser or the Hornady Lock-N-Load Auto Charge Powder Dispenser.If you have,which one do you like the best?

I've used the RCBS Chargemaster, but not the Hornady.

The Chargemaster is one of my favorite reloading tools. No problems with it, very easy to use, and very accurate.

I don't think you would be dissapointed with the Chargemaster.

I've owned the RCBS unit for about three years.My RCBS Uniflow sits in its box these days. Easy to use,dispenses well even with stick powders like Varget and quick enough for me.By the time I've seated the bullet and dropped the loaded round in its box, the next charge has pretty well dispensed. Great for working up loads as all you need to do is cancel the last load and dial in a new one.
I give it a big thumbs up!!
