I have and have used:
1) RCBS: Good, but a bit if a pain sometimes. You need different collets. No good for the odd mistake, is press mounted and you either have to have it set up in a different press or remove your dies or wait until the end of the loading cycle. It does leave a mark most times, even when you are careful, but all still re-shootable.
2) Bonanza: OK, quick but crude. Can leave a mark on the bullet. Puller can get damaged if you are not careful (ask me how I know this
, don't lend it).
3) Kinetics or Quinetics or whatever hammer:
Excellent tool to have beside the bench, Get the green original one with the one 3 piece shellholder. It is a bit fiddly until you get used to it, but works well. It is important that you do not use it like a normal hammer (you are after velocity, not impact under the hammer head like normal hammers). Read the instructions carefully. You have to hold the end of the handle between thumb and forefinger and position the hardwood (I mean real hard hardwood) so that you strike at the most advantagous position, lift it high for a good stroke and whammo! Most things take a couple of strikes. Despite the warnings, somethings need a concrete block or floor. Be careful or you will break the tool here. Make sure the angle of the blow is 90degrees, etc. I've had mine since 1981 or 2 and it looks a bit wonky on the end, but still works a treat.
The quickest bullet puller is your trigger finger. Unless the ammo is suspect, I'd just shoot it off.
If you are going to do a lot of reloading over the coming years, I'd recommend you get a hammer first, then get the RCBS kit later. Both are handy in their own way. Mucked up the seating depth on two rounds? Get the hammer out. Got 200 mils sup that you want to pull the bullets on (you are a masochist aren't you? Don't worry, we all go through the same stages
) Set up the RCBS puller and get on it.
Some guys recommend using a normal shellholder in the kinetic hammer, I haven't tried this, but it would not be so fiddly and a lot quicker.
Good luck, Mick.
