I recently aquired one- With handloads (and a scope) it shoots on par with a remington 22-250 at 100 yards (1/2"-3/4" groups for two different shooters) Don't know about further out, but it is on par ballistically with the 223.
ammo availability is a bit hit or miss, but we have found it simple to run annealed once fired 30-30 brass through a 25-35 die, trim it, and run it into the zipper die.
I would mention that the gun came from a semi-retired smith, and he admitted to a trigger job, and my have done more tuning.
