In 2009, I plan on going elephant hunting with a 585 AHR shooting 750 gr FMJ Woodleighs. A couple of days ago, I loaded up 4 rounds each of 141,150, and 153 gr of H4350 pwd. On the average, this yielded velocities on the Chrony of 2162, 2401, and 2483 fps. The 2483 series had one sticky case, but the primers were fine and I could hold on to the rifle--no problem. All of the loads should be suitable, BUT?

Question: Which load or velocity would you recommend for the elephant hunt, assuming frontal brain shots and why?????????????

I would opt for the 2160fps load.

First, the nominal velocity of the 577NE, a renowned stopper of first order, is 2050fps out of 28" barrels. Actual typical field velocity is probably nearer 2000fps in real rifles. What was fantastic in 1930 will still be fantastic today. Another 160fps will only add penetration and knock down performance to an already well proven standard.

Second, the sectional density of the 750gr solid is .313, well within the range at which velocities of ~2100fps have proven to provide sufficient and more penetration for similar SD solids. And the 577NE, at ~2000fps retains an enviable record on elephants. Again, another 160fps can only add performance to an already proven standard.

Third, while you hope for the best, you should plan for the worst. The worst here would be missing the frontal brain shot, not an uncommon occurance, even amoungst experienced elephant hunters - internet perfection aside. In the event that you do miss, you will want to be able to immeadiately place a second shot within the heart-lung region. Less recoil will surely help with the speed of the second shot and perhaps with its accuracy, though the heart-lung region is quite large.

At 2400fps, .585" and 750grs is too much of a good thing.

My 2 cents.

If it's and 18 or 19 pound rifle
go full tilt.
If it's under 14 pounds I vote for
2162 fps.
If it's under 13 pounds it needs
weight within it's center 33% of
it's overall length.

Maybe 500grains will speak, He used a 585 nyati on one of his elephant hunts, I think he told me he was getting about 2200 and he did not get the pen. he desired.

I go with the 2400fps load should be plenty. My old 577 would put a wop on some stuff, but never shot a jumbo with it.

...so? Can you get a fast follow up shot if NEEDED If not, then they they are only a stunt load. I have shot a lot of big and fast loads, I would not take a stunt load on a real hunt for DG. It could get someone killed.

You need a Penetration Index of around 100. Just go to the formula and calculate the velocity required to get it. You've got my book.

i would shoot the ones that are
1: inside the bullets performance envelope
2: the load is could shoot THREE with, as fast as possible, and hit an 8"plate at 50 yards, under 10 second bangbangbang

that would be the 2050fps load, btw

Here's a Picture of Rob's 585 nyati recovered bullet, 2350fps from an eland a couple years ago ... this is the effects of going TOO fast for a 750gr woodleigh

Not necessarily comparable, but I plan on 2,200fps with a 640gr GS-C (if I ever get them) or 750gr Barnes Banded Solid @ 2,050fps in my dad's 585AHR for Cape Buffalo next October. Both loads give 7,000lb-ft ME. From all that I have read either will give exceptional penetration and knock-down. We'll find out for ourselves, though.
Good luck - sounds outstanding and I am sure Bitterroot and Ed Plummer will want a field report.

Good replies, all. Almost unanimous votes for the 2150 fps load.
Will look up the penetration index in Bill"s book too. My concern was penetration for the frontal brain shot, but as it was stated, it is probably wise to select loads for penetration as well as the ability to recover for three shots. So will practice for three shots at 40-50 yds in a three-four inch dia circle in a 4-6 sec time period.

I might have some of these answers to the penetration question if the Aussie customs didn't confiscate my 585 AHR ammo last Sept before my Water Buffalo hunt in the NT. They rated my rounds as warfare ordinance,

Appreciate the comments!

Dak

Its not the velocity its the ft lbs that count.

I would say that you have them covered.
