I just pulled 95 30-06s last week. Out of the first 5 shots from this lot, 3 cases cracked. So it was necessary to salvage the balance of components. I used my hammer type puller, with a foam ear plug in it to protect the bullet. You really do need to beat something solid, like a concrete garage floor. Even my wooden loading bench doesn't isn't solid enough for this. If you beat a surface that "gives" a bit, like wood will, you end up having to work twice as hard. I do have a collet type puller too, but never use it because it seems to deform the bullets too much. I was pulling Sierra "match Kings", and they're too expensive anymore to risk the collet puller.
