I bought my rcbs see through green all plastic puller about 1975 and it still working fine. The aluminum shell holders wipe out quickly and I went through two or three sets before going to a standard shell holder. I have no problem pulling pistol or rifle rounds. The worst are the light weight 22 cal bullets as they have the least mass. As I said earlier, how you hold it determines how long it will last and how well it will pull bullets. A friend I loaded with bent the aluminum handle on one then got a rcbs all plastic one and broke the handle on it, both in a one year period. To make one work well and last DO NOT hold the handle firmly. Hold it loosely with thumb and two fingers on the very end of the handle and swing it very fast and strike it on steel or concrete so that it rebounds freely and your hand isn't still driving forward. The harder the surface you hit the faster it will rebound if you let it and the fast retreating puller head helps to pull away from the bullet that is trying to go forward. Try this IT WORKS and you can reuse your bullets.
