Just in the middle of reading the biography of Carlos Hathcock by Charles Henderson- Marine Sniper. The book certainly has me drawn in, am up to the chapter about the Apache, the man hating female sniper- very frightening. Anyway, It is amazing to think what Hatchcock and the lads were able to acheive with the .30-06, loaded with the 173 grain Sierra BT at 2550fps. Henderson states that Hathcock kept his M70 zeroed at 700 yards. I crunched the numbers using the current 168gr SMK and for a 700 yard zero, the bullet would strike around 24" high at 100 yards, 59" high at 375 yards and from there, gradually fall to its zero. I wonder if this was actually the zero he used or if Henderson has not gotten it quite right. I have been working on a client's .30-06 today, its a very old Parker Hale/ Mauser action/ English trigger/ English light weight barrel in OK condition for its age. It had a re-stock and I was asked to bed the old girl. Seems to like the Hornady 165 grain BTSP at 2950fps which for an old rifle, is a healthy load. I will probably take it out for a couple of long shots before the rifle goes back to the owner so it will be great to give it a work out. I certainly have a lot of respect for how guys like Hathcock and also match shooters, have been able to use the .308 and .30-06 and read the wind at 1000 yards. With my .308 culling rifle, I am absolutely hopeless past 450 yards. Although I should learn to use the .308 out further, the .30-06 is very appealing. Have any of you guys become smitten with the old .30 for inexpensive LR work?
