Hi
Anyone got a good case forming load using H4198 and .17 M4 brass made from .223?

.17MkIV brass made from 223Rem brass if formed correctly is already there and should not need any special loads to fire form to your chamber, at least not any more than factory loaded ammo for a standard chamber like the 223Rem. Just use any of the listed recipes for the 17MkIV remembering to start low and work your way up and they should fire form nicely to your chamber.
