I used to use them all the time. Yep broke a handle or 2 in the past. But I always had replacements from estates sales etc. Now days I use a RCBS Bench mounted priming tool. In fact yesterday I got another at the gun show for 10 bucks. Didn't have the primer tubes but hey I have plenty of them anyway. Yesterday I also got a NIB RCBS hand priming tool. Single priming..Paid 5 bucks for it...It'll probably go on the infamous Fleabay.... The original Lee single primer tool was of course pot metal body with a screw in shellholder. They also came in the Lee Target Model Lee Loaders...which was a very neat item and worked very well for it's intended use. I used them extensively for my 222 22-250 and 243 varmint rifles
