I had a synthetic stocked 7600 in .270 for quite a few years, and the deer never seemed to mind the forearm not being silent, either 😁 I did mind getting jacked in the cheekbone by that sharp combed stock, though, so I got rid of it eventually. It was a dang good shooter, under MOA with h4350 and a 130 Win PP bullet.
Never had a 742 or 7400, but a friend of mine has an older 742 in .308 that has always worked perfectly both on the range and in the field.
