I have had the Ruger for about 7-8 years. I was not pleased with accuracy with factory ammo, getting around 2", but, with handloads and a Timney spring and sear installed, this rifle is a shooter.
My handloads use 13gr Lilgun, WW brass, a small pistol primer, under a 45gr Barnes XLC, assembled with Lee Collet dies. Velocity is around 2,900fps with this load.
It is not the 'K' hornet.
