Not sure why you would want to do that, though.
Because if you have a need for a .22wmr level load (noise, is often cited) and you have a Hornet, it is cheaper to load down the Hornet than it is to buy .22WMR ammo.
And, once tool costs are paid for it gets even cheaper with cast bullets.
My old (1970) Lyman manual shows a cast 45gr bullet over 3.5gr Unique doing 1669fps from the test gun a 26" barrel Savage 219.
Its the starting load listed, along with 6gr 2400 (1635fps) and 7gr IMR 4227 (1727fps) for that bullet.
Isn't this the ballpark you're looking for??
Loading for the Hornet is finicky, painstaking work, becasue the brass is THIN and cases, bullets, powder charges are small, but other than that its straightforward and no different from any other bottleneck case. I do recommend either a very generous chamfer of the case mouth, OR using an expander die (Lyman M) to flare the case mouth SLIGHTLY. BT bullets are also helpful. Case neck brass is very thin, and very easily buckled,
I've never been a fan of the .22WMR, not due to its performance, which is respectable, but due to the fact that I've always felt it cost much more than it was worth. AND its not reloadable. Last time I bought .22WMR it was $6 a box (tells you how long ago that was,
) and it was more than 6x the cost of .22LR and NOT even close to 6x the performance.
I've never actually loaded down the Hornet, (no reason to for me) but I've always been pleased with the idea that I could, if I needed to.
Good Luck!
