Light bullets have less inertia, and crimped bullets are more difficult to pull, no getting around that. Still, I find the Orange Hammer I use to be more efficient that the RCBS collet die I used for years. Time after time no matter how tight I got the collet, it would still often slip. Not much is as frustrating as tightening the collet as tight as possible, using a cheater wrench, to the point where you had to hammer on the handle to get it to loosen and still have a bullet slip free.
Doing that two, or three times every two or three rounds made it a real pain.
I had overlooked the hammers for years (decades, actually) and when I finally decided to try one (and it was cheaper than the collet die) I got the big Lyman one, not the smaller RCBS one, and it has worked like a champ for me.
Pulled down 400 rnds of 7.62 Nato in maybe an hour and a half and most of the time was removing the pulled components and putting in another round.
GI milsurp stuff, crimped and lacquered and 5 or 6 wacks (or less) did the trick.
Pulling down .223 and some .22-250 rounds actually took a bit more work, due to the ligher bullet inertial, but it was usually a matter of another couple wacks, or three. And the hammer will pull lead bullets undamaged, something a collet puller will not do.
Maybe its just something I'm naturally good at, or maybe its the fact that I get to HIT SOMETHING while doing needed work, either way, for me the hammer is the way to go. YMMV
