RCBS Automatic Priming Tool: Review
The RCBS Automatic Priming Tool is a bench-mounted, single-stage priming tool.
I’m not sure why it’s called the RCBS Automatic Priming Tool, unless it’s because the primer automatically falls into the priming rod cup when the user manually pulls the feed arm over it. I would have named it the RCBS Bench Priming Tool. Having said that, it’s a very effective tool for high-volume priming.
It comes with everything needed to prime with small or large primers, and can be configured to prime with either one in just a few minutes. The two parts that have to be changed according to primer size are the primer tube and primer rod assemblies. The primer tubes can be filled with up to 100 primers at a time. Once the primers are all facing cup side up, you pick them up with the plastic nipple on the end of the tube. I used my Dillon Primer Flip Tray to get them facing the right way.
The other end of the tube uses a retainer clip to keep the primers from falling out until the tube is placed on the Automatic Primer Feed Arm. If you’ve ever used a Dillon progressive press, the primer tubes with be very familiar to you. Below the hole where the tube sits, there’s what they call a Stop Pin. The spring-loaded stop pin keeps the primers from falling out of the tube until the feed arm is pulled over the priming rod cup. The cup depresses the stop pin, allowing a primer to fall out into the cup. It works very well, and can be cycled much faster than it took me to type this sentence.
The RCBS Automatic Priming Tool uses standard shellholders, which clip into the main ram just like they do in a press.
I’ve used both RCBS and Redding shellholders with mine. Once the primer is dropped into the priming rod cup, simply lift the handle, insert a case, and push down on the handle to seat the primer. The handle has enough leverage to firmly seat every primer, yet enough “feel” to know when you’ve hit the bottom.
The overall build quality of the RCBS Automatic Priming Tool is impressive. This thing is solid, and as soon as I pulled it out of the box I knew it would last a long time. Other than the nipple on the end of the primer tube, there are no plastic parts. A casual glance at my shooting log shows I’ve seated around 6,000 rifle primers with mine since early last year. I’ve had no problems with it and would buy it again. I bought mine from here.
