Before this reincarnation of the rifle, I shot the 240Wby with a Douglas 1-10 twist sporter barrel on a Fajen stock for a decade or two. With an 85 grain bullet, either Speer SBT or Barnes X, it was a wonderful combination for the eastern white tail deer at ranges of 50 yards out to maybe 200 yards. I do not remember killing a deer further than 200 yards because of the way I hunted. I am sure that the 85 grain bullets will work further but I just never used the rifle any further.
The reason the 105-115 grain bullets are so deadly at ranges beyond where most people fear to tread with a small bore is the high sectional density and high BC of the match type bullets. Even though the bore diameter is small, the thin jacket expands well and causes a large exit wound. The long bullet has plenty of lenght to let the front expand and still have mass to break bones and penetrate on through. This process was apparent on the twofer pigs I shot where the bullet was continously shedding jacket and weight as it went, such that a bullet with a lesser sectional density would never have exited the second pig. This is generally the same principle as the Nosler partition which always has a high retained weight, except you give up the partition and in return get accuracy and high retained velocity with the VLD.
We all live our lives differently, and to me, the challenge of new personal goals is what gives me personal satisfaction. Just seeing one more animal dead has little meaning to me. Practice and more practice is the thing that helps in achieving new long range goals.
