.22 Ackley Improved Hornet Reloading Questions

Hi,

I am about to get my hands on a .22 Ackley Improved Hornet. I have been looking for die sets or reloading info without any luck.

I am currently looking for answers for the following questions.

1. Does this round head space on the case shoulder or is it the rim of the case?

2. What is the procedure in reloading this round. My thoughts are:

Fire form .22 Hornet
Neck size case with std .22 neck die
Throw away case after every 2 or 3 shots.

3. Is the rifle accurate firing the std hornet cartridge?

4. Is the powder info listed for the K Hornet usable for the Ackley Improved.


Thanks for any assistance.

I have looked in my Ackley books Vol. 1 and 2, cannot find any reference to a Ackley improved 22 Hornet.
Chances are it is a 22 Hornet rechambered to 22K Hornet. The only way to find out what you have is to compare fired case's or a chamber cast.
I think the seller is trying to make the rifle sound better than a 22K and is using the Ackley name.

Hello, UncleGrumpy. I am sorry I can't help on your Ackley Hornet...However, I do have an Ackley .22 Bee. I have this chambered in a Shillen barreled customized Australian cadet. Now when the chamber reamer arrived from Pacific Tool, I didn't care for the short neck..thinking of possibility of shooting cast bullets in future. So I had them push neck back to original Win. .218 bee length.
I headspace off case rim, I use start loads for std. .Win. 218 Bee.
I am confused about your thinking of throwing away brass after only 3 shots. I have a std. .22 Hornet..which "everyone" knows eats brass alive..what with that 5 deg. shoulder..this is in an original Sharps-Borchardt action. Shillen chambered this one with minimum dimensions & very tight headspace (asked Ed to build as if it were a bench-rest gun). I am still using same RWS Hornet brass now for over 10 years. If action locks up tight..& chambered close..and you don't "hot-rod" it..those cases should last a very long time.

All AH's (17,20,22) headspace off the neck. Keep a crush fit and you won't have brass problems, also annealing after about the 4th or 5th firing.

Get 22 Hornet brass, anneal, fire form, resize, don't push the shoulder back, load and shoot. As long as you keep the headspace tight you can hot rod it and not have problems with head separation. Split necks are more common.

Interesting post. I shoot the K-Hornet, and have always worked on the assumption that it headspaces on the rim, just like the regular Hornet. I can't speak to the AI Hornet.

Check the Redding website, they might make dies for the Ackley Hornet. They won't be cheap.

Oh.. forgot. I fireform my brass using my standard load for the 40gr hp bullet I shoot as a fun load. Probably around 2500-2600 fps, IIRC. Accuracy is as good as with the fireformed brass, no need to worry there.

Thanks for your replies.

I haven't found any dies (or much else info) on the .22 hornet AI. I guess I follow impalacustom's advice as far as treating the brass.

I was also of the opinion that every rimmed case was headspaced off the rim.

Do I use the standard .22 hornet neck sizing and seating die?

cheers

I imagine you can.. I do that on my K-Hornet.
