M64 Question
I have a 1416 that is newer mfg. With Lapua Master L and Rem- Eley Match I can get .3" at 50yd. if I do my part and the wind cooperates. You have a nice rifle there.
You might need to give a careful cleaning with Shooters Choice Lead Remover then shoot it back in with lead target ammo for a few rounds then test it again.
