Because the bullet is so short on the CB caps, you probably need a slower twist barrel than the standard 1:16 that's in the normal .22 rimfire. The .22 that I had built to shoot the 60 g Aguila SSS shells has a 1:9 twist and it'll group 2" @ 200 Yds on a calm day. To do that, I had to have a 20 moa scope base. I can get is zeroe'd @ 50 Yds, and there is just enough elevation in the scope to get it to 200 Yds.

I believe the muzzleloaders that shoot round balls have a 1:32 or 1:48 twist.

The .22 WMR is a good round and has been around for a LONG time. The .17 HMR uses the same case, just necked down to .17. For distances of 70 to 100 Yds, the .22 WMR will do what you want as well, admirably. If your range estimation is off, the .17 HMR shoots flatter. I haven't checked prices on the ammo to compare them, but either will be cheaper to buy ammo for than the Hornet. My Mach II seems to be louder than my .22LR, but then again, I'm shooting standard velocity ammo in the .22, not the hyper velocity stuff.
