Like Res45, I love that 358-125-RF for 9mm. All my 9's like it except the CZ75B - its chamber is a little tight even when I lube/size to .357. Just ordered the 6 cavity Lee 356-120-TC. Truncated shaped bullets have treated me well in 40S&W and 45ACP. They feed good.
As far as Lee molds go, I too have had issues with the pins. One thing that seems to help is to back out the pins when cold and use some threadlock when re-installing. Let it sit for a day or two. Also helps to get the molds good and hot before beating on them.
I too use sponges, a lot. My drop bucket of water is full of sponges to let the bullets trickle down without bumping. However, my cool off sponge can be good or bad. It takes a while to learn the mold, where wrinkles like to show up, where to cool and not to cool. For example, if the base of the bullet is sometimes hard to fill, don't cool off the sprue plate, only the lower mold body. And vice-versa. My semi-wadcutters DO NOT fill the ledge below the bullet cone if over-cooled.
