I have pulled a lot of bullets...... see hall of shame...... any how, rcbs works very well. I can re use all the bullets I have pulled except maybe one or two. One reason I have pulled so many, besides the screw ups, is I had some 338 lm loads put together some time back. I have since determined the right load for my rifle and pulled all those, 150 rounds, and reloaded them. Saved my barrel life a bit and now shooting better rounds. I have the collet for each caliber I load. Its just automatic. When I start buying dies for a new caliber, I buy the collet.
