haven't used one foor probably 30 yrs or so. Broke two of them and didn't bother buying another one. I may have been too hard on them, whacking them on a cement floor, but, whacking them on a 2x4 wasn't doing the job for me. What I didn't do back then, was make sure I'd broke the coldweld by breaking it, by seating them a bit deeper, enough to break that weld, maybe .010 or so. I don't really need one anymore, may have been useful with cast bullets, but, wasn't about to run out and grab one for just that. I can see their usefulness for that and stuff like round nose pistol bullets, or stuff seated too short for a collet puller to grasp, haven't had a need for it in a long time.Hey, just wondering if anyone that has broken their rcbs hammer type bullet puller have the nut just laying around still intact? I broke mine and thought I would try here before picking up something new. cheersView attachment 994067
