It took two 250 gr Nosler Partitions from a 340 Wby at approximately 200 yards to kill my Eland.
The first shot off the sticks at ~200 yd was about perfect on the shoulder. The 250 gr Partition broke both shoulders and hit both lungs but the Eland did not get the memo and took off at a gallop.
The second shot was an immediate follow-up, off-hand at a run away rump at ~210 yd and I owe it more to luck than skill to have connected. The 250 gr Partition plowed all the way through the paunch but did not reach the lungs. This is where a TTSX or an A Frame are likely better than a Nosler Partition. The NP shed its entire front core and did not retain enough mass/momentum to finish full penetration lengthwise. It delivered enough of a blow however to stumble the Eland forward, and it collapsed within a few yards.
It was a pretty big bull... Hell's own work to get it in the truck! Despite cutting it in two, being 3 reasonably strong men straining at it, and winching it aboard one half at a time, we barely got it done...
My learning points are:
- I really understand why in the golden days, the Brits recommended the .375 on Eland. They have a well deserved reputation for being lead sponges, and the old cup & core "soft" bullets were often a gamble when it came to penetration.
- I really understand why the PH kept asking all morning to NOT shoot unless I had a clear lung shot, and to pleeeaaase break the shoulder on the way in.
- I would not feel stupid with a .375 250 gr TTSX on Eland.
- I feel about perfect with a strong .33 and 225 gr mono-metal (TTSX or similar) or bonded partition (A Frame) from about any reasonable angle.
- I would feel less than perfect, but still confident with a fast .300 or 7 mm (.280) shooting a heavy for caliber TTSX (or similar) or A Frame: 180/200 gr in .300 and 160/175 gr in 7 mm, but I would restrict my shots to broadside or slightly quartering angles.
- I would still feel adequate, but very focused and a little tense with a fast .270 shooting a 150 gr TTSX (or similar) or A Frame, but I would restrict my shots to only perfect broadside at fairly close range to increase the chances of a perfect shot.
If only to summarize what the community keeps saying time and again threads after threads, in one way of another: any bullet of reasonable caliber and good construction through both lungs will kill anything that walks.
Conversely, even the biggest slug in the guts will only be the prelude to a long (very loooong for Eland) tracking job. We all know that, but it bears repeating.
So, yes the .270 kills Eland, every year: all you need is to put in the right spot a bullet that has enough mass, and stays together enough, to punch through whatever bone is in the way and shred both lungs.
Bigger bullets will not make up for a bad shot, but they will generally (and we all know that this rule has exceptions) finish things faster when in the right spot, because they generally break more bones, they wreck more tissue, and, yes, they it harder, however we want to measure that.
I personally like better odds, so I shoot heavy .33 slugs at Eland, pushed by a fair amount of powder...
Just my $0,02...
