I think you're looking to spend a lot more money than you need to.

A lot of people do not know that Hornady loads the Vmax bullet in the 22mag.
You'll lose some trajectory, gain some wind advantage, and gain knockdown power / penetration on foxes with the heavier bullet compared to a 17grain hmr.

The hardest part for you might be finding these rounds, but I'm sure you can get a hold of them in bulk.
