dk17hmr Hello & welcome a board, I have a 219 Zip & 25-35. Botn are great,
I had trouble making 219 brass from 30-30. use 25-35 brass for 219,
You can recamber a 22hornett to 219 by hand yourself, No big deal.
The 25-35 is different you have to have a223 bore to 25 cal by gun smith.
Both calibers I have wanted a long time, Now I have them, Best of luck
Marv.
