Sako Vixen in 222 Rem Mag review; did I ruin this rifle by using the wrong ammo?

In this video I review one of my late father's varmint rifles; a beautiful and accurate Sako Vixen in 222 Remington Magnum. However, I grabbed two boxes of his reloads labeled "222" and didn't realize there was a 222 Remington, and a 222 Remington Magnum. Did I ruin this beautiful rifle by using the wrong ammo?
