I had both, hammer type and Hornady Cam Lock Puller. I picked up the Hornady,... https://www.midwayusa.com/product/1012764862 ,... after breaking two hammer type.
I like to put heavy crimps on most calibers I reload. Hammer types would take a dozen whacks sometimes, so, breaking them is probably a direct result from my crimping,... don't really know.
I think marks on the bullets are mostly a result of bullet type, and crimp intensity. Softer, platted bullets, can result in crimp marks,... but, for target plinking, I don't think it would make much of a difference. As posted, dump the powder, not worth pushing the safety factor.
The Hornady Cam Lock Puller, when adjusted correctly, pulls quickly and with no marks! I'll never go back to a hammer/inertia type puller!
