Have you looked at what is being posted on Rimfire Central?
The .17MH2 is one of my favorite cartridges, probably the best tree squirrel round EVER MADE. But without Eley or Eley-made Remington ammo, the rifles are just candidates for being rebarreled to .22LR.
I bought a bunch of it when CDNN and Centerfire Systems was selling the last of the Remington. I bought 500 rounds of Hornady last year, but didn't get to shoot much because of my prolonged health issues.
