Dillon tips, tricks, and mods. Post them here.

I modified all my 550 heads to floating dies, even the stock Dillon head. It's trivially easy to do.

I had issues with my Whidden seater die, too. I'm glad to hear it wasn't just me. I'm done with those monkeys.

Is this the one i saw many a year ago (somewhere on line) where you place an o-ring under the lock nut. Between it and the tool head? Or some other low budget but works deal.

Kazoo, All you need to do is get Forster, Hornady (maybe) or Whidden die lock rings, screw a die in and back the ring off a bit and drill a hole through the ring into the head (correct size for a properly sized roll pin), then back it out and drill the hole in the ring out so there's a fair bit of clearance for the roll pin to have some wiggle room in the lock ring and drive a roll pin into the hole in the head sticking up enough for the lock ring to sit on it. Then drop the ring on the pin, screw die into ring and head to appropriate depth and lock down the pinch bolt on the lock ring. The pin in the head holds the ring from turning out when it's locked on the die, but doesn't preload the die against the head threads. This lets the die wobble in the threads a bit but still not move in or out.
