	I got the 222 Rem die and Mark even cut it down to 1.22" to eliminate the shoulder and neck. The cases that I had run all the way into a 357 Magnum die with no shell holder would stick out 3/8" by hand in this new die. I ran them all in and pounded them out. Now to shoot them to see how they do. Thanks Mark

	I just got out a new 357 Max case and using the cut down die only, was able to full length size a case ending up with a .373 base from .375.

	Dave, Your belling die got me thinking, a dangerous thing at times, and I got out the re-decapper that I made which is a copy of the 25 Hornet one I got from Bob Zimmerman's estate and evidently is a Weber design. I have made a couple and this first aluminum one is now set up with a 357 Mag/max shell holder. I added a collar that bells the 32 RKS case just enough that it is easy to seat in a high wall but wide enough to seal the chamber. It is removable so I can make additional ones for other cases if needed. Jack

	If you use heavier powder loads you could get carbon streaks on the outside walls and even dimpling of the cases. With the belled case mouths you stop the dimpling or gas getting around the case mouth causing carboning around the outside wall of the cases. You do not need to do it every time. I rebelled the cases after about five firings. Belling is not required if you keep your loads down to 1,100 fps to 1,400 fps. For us shooting in the 1,500 fps to 1,600 fps range then belling is highly recommended.

	My 32-40 Ballard has a very sloppy chamber and needs cases belled every time to avoid blowback. My RKS 25 Hornet will dent a case mouth on occasion but belling with a 30 cal bullet on a handle fixes that quickly with no apparent effect on accuracy. I a pushing the 120 gr Paul Jones spitzer at about 1640 fps. A bit fast but very accurate.
