The Hornet brass that I use (PPU) is heavy enough that it is practical to machine the case necks to leave a shoulder on the inside of the case.  Then the round is simple to load, just re- and de-, charge the powder, and stick in a bullet.   The internal shoulder locates the bullet properly. Ammo loaded this way has shot a 1.5" group at 200 yd.   I am shooting a .262" diameter 75 gr bullet.

What exactly is the machining process to convert from RF to CF?  I'm assuming the Breech Block has to be drilled/filled and re-drilled for a different position on the firing pin.

@Cap45:  If you're converting a Favorite, it's best to start with a .22 breechblock.  I simply bored the firing pin channel to a better angle using a 1/4" end mill, and made the firing pin 1/4 diameter instead of the original, (which I remember as .180").  That cleaned up the old channel nicely.  Even so, the tip is offset from the pin centerline.   

My conversion is of a 1915 Favorite, whose breechblock is wider than the 1894 model.  I wouldn't do that to a "94" Favorite.  Filling the old channel with a brazed-in slug is a much better approach for those.   

Either way, setting the breechblock in the mill at the correct angle is tricky.  I used a method that is too complicated for a forum post, but it avoided making a fixture.  If ever I were to do another conversion, I would send my breechblock to John Taylor, who is much better tooled-up to do the job than I am.   

Uscra112 the intent was to make a 100 identical cases. All or just the amount needed primed, charged, lubed bullets in place and ready to take to a match. Advantage would be to rapidly shoot a good condition before it goes away and or as soon as it comes back. No powder measure, re&de capper or breech seater needed on the bench.

Thanks all; I really like the suggestion of sending the block to John Taylor.  Although, I do have the tooling to drill; tap, and plug the block myself.  Gotta think that one over.

It's been about a year since the last post on this discussion. It contains so much great information, lets keep it alive. 

I went to the range a couple weeks ago with my .25 Stevens #2 rolling block. I was shooting both the rimfire and centerfire versions. I had a couple misfires with my new, home made rimfire cases. They needed a little fine tuning. I went back to the range yesterday with 34 reloadable rimfire cases. They all worked great    Now I need to find some more .22 Hornet brass.

Here is the video from a couple weeks ago.
