I have a Redding die set for my 22K Hornet. I also have a 22 Hornet collet die, but have been using a Redding Type "S" neck sizing die I have for the 221 Fireball. It makes some very good handloads
Here is a typical group with a cheap MidSouth Varmint Nightmare 34 grain Hollow point bullet.
I originally wanted to get a Lee Collet die (I really do like them) for my 221 Fireball. I sent in two fired cases and two bullets (50 grain V-Max) with a check for $54 (I think). they sent it all back to me with a note saying the 221 Fireball was too short to make a collet die for. the 22 Hornet is the exact same length, and it is the an off the shelf item...go figure. Any way that is how I ended up with the Redding neck sizing die. Since the 221 Fireball and the 22K Hornet are the same length, I though I would give it a try and it worked to perfection.
Good Luck and Good Shooting
