Savage is now selling a bolt action rifle chambered in 5.7x28mm. It comes standard with a 1-9" twist. Looks like a 22 Whisper to me.
Doing a stability calculation it seems like it will stabilize a 65gr sierra Gameking. With a 22 can. Talk about a quite varmint gun. And I think it would perform better than the anguilla sub sniper 60gr 22lr. I've heard those are hard to stabilize in standard barrels.
Muzzle velocity: 1,070 fps
Bullet length: 0.85"
Bullet weight: 65 gr
Barrel twist: 9.0"
Bullet caliber: 0.224"
Stability factor: 1.04
The bullet is marginally stabilized
