The "Best" of anything always unleashes a cascade of opinions, especially anything reloading. How can anyone know what is best unless they have tried and compared everything? So, inspired with a crusading spirit, I set out several years ago to buy and try all then available handheld priming tools, as shown in attached pic. (I've bought and tried even more since then but you get the idea. ) The experience netted more than one conclusion, and suggestions to pass along: If you want to impress your friends and neighbors you can do no better than the elegant Magnum Metals' tool, which is beautifully machined from stainless steel, captures and centers the primer before seating, is adjustable for seating dept and fits in your shirt pocket. For $200. you get a beautiful tool that works as good as it looks and provides a satisfying helping of pride of ownership. But even so, in my opinion it's definately not the "best" because I don't like handling primers one at a time. Same with the nicely made, sweet working Sinclair hand seater and its pretty clones thereof. But if no auto primer feed it's no deal for me. Which is why I give high marks to the Lee tool of a generation ago, which set the standard for a lightweight, inexpensive, self-feeding hand priming. But alas, they are inclined to break, as if self-destruction is built into their DNA. Having said all this, my favorite "best" is the
OLD STYLE Hornady hand tool. (Definatly
not their current model, which I cannot say enough bad things about.) They are comfortably hand filling (as is the RCBS tool) have good leverage for easy primer seating and possess features lacking in all other hand tools: mainly being the 360degree three-way work positioning: (1) You can hold it at any angle that is most comfortable in your hand, then (2) rotate the primer tray at the angle that gives a smooth primer feed co-ordinating with the handle, and (3) rotate the shell holder so that you can position the shell entrance at an angle that works comfortably and effeciently. No other hand tool does all of this, which is why even used
old style Hornady hand primers now fetch $100. or more, if you can find one for sale. Attached pics include the OLD Hornady BEST hand primer, and workings of the lovely Magnum Metals tool.
