[QUOTE="greenejc, post: 1631503, member: 60453"] I do a little bit the same, except I use the Shepherd P series or V series scopes for most of my rifles. I can zero my 30-06s or my 300 winmags for 100 yards and use the bullet drop circles in the front focal plane to range my target on the fly and because the bullet drop is calculated into the ranging points, when the range is determined, the bullet hits inside the ranging point, within one minute of angle or less. Practical ranging with this system in the 3x10 scopes is about 600 yards. Beyond that, I need a range finder, because bullet drop is too great between 100 yard aim points and even at 10 power, some precision is lost. The 6X18 V series can be used farther. Precise aiming can be done using the 1 inch at 100 yards vertical ladder on the side bar of the scope and a good range finder, allowing precise shots to be taken far beyond the effective killing ability of most projectiles in either of these rifles. I do play with both the 30-06 and the 300 winmag at long ranges with these scopes, along with my real elk rifle, the 35 Whelen. They will allow consistent hits at 800 to over 1,000 yards at the altitudes where I hunt elk. I don't think I'd try to kill an elk with any of them past about 600 yards, though.
