Yep. Bought as a 16" .17hmr, it's not a two minuite change like the Sako quad, but it's still only 5 mins, but that's fine, it's not like you suddenly decide 'oh that rabbit is 40 yds, I'll swap to .22 ' it's a shooter, my best group so far is .146" at 100m. Admittedly, I can't get that now, hmr ammo quality has gone downhill, proved by checking against my original batch of hornadys. I'm glad I kept some as a 'benchmark' round.
