I just bought Hornady's updated hand priming tool. I have their first model,which needed bushings to use RCBS shell holders and it was a bit of a hassle to change holders and primer sizes. The new one has a separate tray for use with RCBS shell holders.

I primed a few cases with it. It looks to be a good product, better than the old one and much better than the RCBS hand priming tool. I bought the RCBS when they first came out. I had nothing but problems with it. It sits gathering dust, it will probably go into the trash.

I have a Lee hand priming tool which I keep set up for small rifle. It also is a good product, but the Hornady is sturdier.

For someone who is buying a hand priming tool for the first time, I would recommend Hornady's new tool. It is also easier to change to different shel holders and primer size. Hornady thought this one out with the new tool.

I've spent a lot of money on tools, some work, some don't.

Do I have to buy Hornady shellholders to use it or can I use my Lee shellholders?

I bought and got rid of one of the original ones, sure glad to hear they've done away with the plastic bushings to change primer size. I have two of the Lee's, one set up for small primers and one for large primers. That along with Lee's shell holder set works great for me.

I believe you can use the Lees as long they are for a press, not the special shellholders you use for their priming tool. To be sure, I would E mail them.
