journeymen,
Regarding HalfaDouble's comment about the possibility that your rifle is chambered for the 5.6x35R, Vierling. If it was proofed as a 22 Hornet, it should be marked 5.6x36 (they did not mark the "R"); if it was proofed as a "Vierling", it should show 5.6x35. When you take it apart, you should be able to see which it is. If it is marked 5.6x35, but will close on a 22 Hornet case, it was likely rechambered in the US and not reproofed. Both cartridges are smokeless versions of the ca 1885 22 Winchester centerfire they are very similar, the main physical difference is the Americans made the Hornet rim thicker so it would not chamber in 22 Win. CF rifles. Loading the Vierling is pretty easy once you thin the rims of 22 Hornet cases and deepen the primer pockets or buy cases. I use normal Hornet dies and shell holder and load to a little over 2300 fps with a .223" 45 gr bullet. Bullet diameter may vary (even with the Hornet). Enjoy.
Mike
