I know this is an old thread, but just wanted to post an update. I used CCI SV rounds hollow pointed with the Waltz die on my recent hunting trip to take beavers, raccoons, opossums, rats, mice, voles and armadillos. Unfortunately no coyotes. The hollow points were accurate and did a great job on everything I shot with them, and the standard velocity rounds were nice and quiet through my suppressor. We really put a hurting on the raccoons, which were climbing on and damaging my buddy's feeders.
Also, I just got a Taurus TX 22 compact to use as a suppressor host. I'm in the process of wringing it out with different kinds of ammo to find what it likes. Velocity is low enough with a pistol that hollow points will not expand, so flat points are the way to go. I made some last night with CCI Blazer 40 grain ammo and the gun fed and fired it with no issues. It's quiet too! Should be a nice kit gun to take along hiking, fishing, etc.
