I started with a Sako Quad in HMR and as my sole rifle, absolutely loved it and proved it devastating on rabbits, comfortably out to 150 yds. Once I added .243 a "quiet" rimfire was more appealing and appropriate. So, I added a .22 LR barrel, which combined with subsonics, is superbly quiet and still deadly on rabbits up to 100yds (and with less meat damage). OK. I've lost 50 yds distance, but on my permissions that's less of an issue than the noise and so I doubt the HMR barrel will be used again for the foreseeable future. The beauty with the Sako Quad, is this flexibility (and can always add an extra .22 WMR barrel - a better foxing round [up to 100yds], than HMR). One may not have a requirement or desire for different rimfire calibres now, but things change and in the meantime, one can enjoy and appreciate the quality of a Sako rifle.
