    Curdog, be aware there are at least two versions of K Hornet. The original is the Kilbourne version which has 35 degree shoulders, then there is the Ackley version with 40 degree shoulders. I’ve got the original version with Redding 35 degree dies for my Ruger 77/22 K Hornet.

    Be sure the reamer used is a minimum specs reamer or a custom grind to under the usual Hornet SAAMI dimensions at the web and just ahead of it. I have one by Clymer that is a waste of good tool steel. Way oversized, brass comes out looking like a pregnant Hornet and lasts only two reloadings before it separates.

    Let me preface this with saying all the loading for the Hornet that I have done has been for light squirrel loads using cast bullets and it has worked out real well. I haven't shot any given lot of brass enough times to know for sure, but with the neck sizing and light loads, I don't see brass life as being a problem for me.

    Is the K Hornet conversion really worthwhile? Reading around on the web it just seems like two cartridges, the .22 Hornet and .45-70, seem to attract people who want to make it something it's not and was never intended to be. Again, my experience is limited and I got into the Hornet with specific goals that were quickly met and I don't intend to do much else with them, but I like the little cartridge as it is.

    I've had 22 Hornets for years, also had a couple K-Hornets. In stronger modern actions, such as the CZ, with modern powders such as Lil'gun or H110 the standard 22 Hornet will out perform the what the K-Hornet was touted at back in the day. I currently have 3 standard 22 Hornets and see no reason to K-Hornet chamber them. Out of my Savage M40, Contender and Ruger #3 the 45 gr Hornady at 2950 fps and sub moa accuracy is all I need from the hornet.

    I also neck size with a Redding Bushing die but the Lee Collet works as well. Using the FL die backed out results in crooked necks most often. Using a Lyman M-die to expand the neck, with jacketed bullets especially, so the bullet is started into the case before seating negates crushing the thin fragile necks during seating.

    I'm late to the party, I've got 3 Hornets and 3 K's. All of the K's were not rechambers, the barrels were chambered from the get go as k's. With today's bullets, powder, and nice chambers I won't buy anymore K's.

    I'd rent a 22 K hornet reamer and re-chamber it. It will out perform the standard hornet. I had a Ruger # 3 I re-chambered that I traded several years ago that I regret!
