I make cases for my 5.6x35 R Vierling by thinning 22 Hornet rims, from the rear, by enough to allow the action to close (around .010") and deepening the primer pocket with a Lyman primer pocket uniformer. In addition to being easier, it removes the Hornet headstamp. Sectioning a case after performing this operation showed sufficient "meat". Slugging my barrel showed it has a .223" groove Diameter. Bullets of .221,.222,.223, and .224" cand be found with a diligent search. It is best practice to determine the actual groove diameter when deciding which diameter bullet to use. I use standard 22 Hornet dies and shell holder, adjusted to headspace on the shoulder. If the particular rifle demands a small bullet, the expander button may need to be changed or adjusted to provide enough neck tension. I do not yet shoot cast bullets, but plan to do so, and have bought appropriate mold blocks.
