Hi danxt
The .243 is the best deer caliber ever invented. It will cleanly and humanely kill
any deer you
ever see at
any range you
ever have any business taking a shot at. It will do so with more than one particular weight bullet.
In general, .243 bullets of 90grs or more are designed to penetrate better and expand slower which is to say they are designed for deer/antelope.
In general, .243 bullets of 85grs. or less are designed for very rapid expansion which is to say they are intended for varmints.... and they DO open up much faster. However I've found the Hornady 87gr. BTHP stays together much better than the lighter bullets. I also know someone who uses the 85gr. Sierra Gameking bullet with good success on deer.
I have killed a trainload of deer with one-shot kills using the Hornady 87gr. BTHP which - theoretically - is a "varmint" bullet. A couple have been beyond 400yds. I have dropped deer with the old 100gr. bullets beyond 300yds. Just recently I killed a doe at about 260yds. with one of the new Hornady 58-gr. V-max bullets - but that was a head shot. I also killed one at about 60yds. with that bullet with a lung shot - she went about 100 feet before keeling over. Though I am "
two-for-two" with the 58-gr. V-max, I have decided to NOT use it anymore on deer. That is partly due to the fact that they are more affected by wind.
My rifle is (was
) "zero'd" at 275 yds and here is the trajectory chart for it with the Hornady 95gr. SST bullet...

You can see that out to 300yds. I can use virtually the same point-of-aim and be sure of a lethal hit. From 350yds. to about 450yds a point-of-aim slightly above the top of the deer's back will produce a lethal hit (in the chest cavity).
The difference between the 95gr. bullets and 100gr/105gr. bullets is not enough to change that point-of-aim substantially. But of course you can always fine tune your sighting for the different bullet
The muzzle velocity of - for example - the 87gr. BTHP or the 95gr. SST can easily (and safely) be made to 3200fps. by reloading. I still favor the 87gr. BTHP (or spire point) because it will also open up well
at shorter distances and I like to have the bullet expend
all its' energy
inside the deer.
The blast and recoil of the .243 are very, very modest and that is a
tremendous aid to accurate shooting
(Sorry the numbers aren't spaced more evenly. I type them evenly spaced but the "translation" to the forum scrunches them all up)
