Was a little disappointed with mine. It is hard on the gripping hand (needs rubber coating). It does mar the bullet. Not enough that it is not useable. I would like to try vise grip and channel locks with duck tape or plastic in the jaws. It just might work as well.
I guess I don't understand your issue as I have pulled apart crimped loads to investigate what's inside. No issue.... I have the multi version non mil-spec one so I can pull almost anything. It takes very little effort to squeeze the bullet. I suspect this may be a user issue.
Who are you addressing?
I had to pull 40 rounds. I just expected more for $50. Rubber coating would have been nice. I saw Sears or someone advertising channel locks or vise grip with rubber or plastic inserts to cover the jaws. I just wondered if these would do the same job or better for $20.
I think most on this thread seat bullets with minimal neck tension and especially avoid crimping. The grip-n-puller works great in this scenario. It is more difficult, if you are trying to pull a bullet with a factory crimp. In this case you will probably mar the bullet beyond reuse. Sometimes a puller like the RCBS that mounts to the top of the press is nice but they are expensive (due to having to have different collets for different calibers), are somewhat slow and will mar just as much trying to pull a crimped bullet. Now if you have a crimped bullet and just want that sucker back, no matter what, use a hammer kinetic puller. Problem with those is, they wear me out, are slow, and can ruin the powder by crushing. I guess the perfect bullet puller has yet to be created, as far as I know, in my little world anyway.
