Will .222 Mag rounds fit into your magazine? Many years ago I had a Sako short action fitted with Douglas Premium barrel and chambered for .222 Rem Mag. The gun shot great, extremely small groups, but the bullets had to be seated very deep to fit into the short magazine. I had a local gunsmith open up the front of magazine so I could fit 3 rounds in it with longer seated bullets. The gun worked fine but was limited to 3 round magazine capacity for my handloads.
