Are any of you guys familiar with this hand priming tool? If so, I would like to know about its quality. I have about had it with my Rock Chucker priming arm and am ready to order a hand priming tool right away. I had the Sinclair in my cart at Brownell's, but they are sold out of the priming head tool for 338 Lapua. I was set on getting the Sinclair, but I need a priming tool right away and can't wait for a back order for the 338 head tool. I've searched the web, looking for a decent hand priming tool, but I'm not having much luck. I am only interested in a single feed tool and definitely want a good quality tool. I found the 21stcenturyshooting.com hand priming tool and it looks interesting. I'm tempted to order it right now, but I thought I would come here first and see if anybody has any experience with it. If anybody has any feedback for me on this, it would be much appreciated!
