PapaD, Two to three inches is enough eye relief for a 7mm mag. Just make sure your stock is tight against you shoulder. Sighting in and elevated shots from the sitting position are times when you must pay attention. Use a rest or sandbags when sighting in that elevate the rifle enough for you to be in more of an upright position. A low position tends to have you creep up on the scope and possible ring around the eye. When sitting and shooting up hill turn a bit to the side. If you a right hander, turn so your shooting over your left leg. This will be a more stable position and help eliminate a third eyebrow.
