I bumped into this on the longrangehunting forum, and thought of Spook's Hornet:
I rebarreled a 22 Hornet for a customer many years ago. It was a Ruger #1 and he wanted to shoot the 80 gr VLD bullets out of it and drive them to subsonic velocity and use a suppressor. The rifle worked very well. It was actually a pretty consistant load that produced 1050 fps with the 80 gr. We used a 1-7 twist barrel that was 22" in length and threaded for a can. I believe he used an AWC can but do not know for sure.
Anyway, Max loads could beat supersonic by a fair margin but he worked with the subsonic loads mostly. It was easily a 1 moa rifle at 500 yards and at 100 yards it played with 1/2 moa with most loads. Not to bad for a ruger #1. It was a neat little rifle.
To do this we drew up a specific reamer for the project. He used Winchester cases so I drew the reamer up around those brass making it a very tight speced reamer in the body and neck dimensions. Normal 22 Hornet reamers are built very loose to old black powder specs in most cases which are VERY LOOSE and not good for case life or anything else for that matter.
If you do this, get a reamer made to the correct dimensions and you will be much happier with the finished product.
I personally prefer a 221 FB with a heavy bullet as it has a much stronger case if your looking to load to top pressures.
