I should say Nigel that I haven’t shot anything at 700m with my Creedmoor. Looking at the log book, 625m and 608m are the furthest (large nanny goats), one after the other, they both bang flopped. There were six 2 yr old spikers between 580m and 600m exactly, on the same hunt that I have posted about before. Of those three dropped on the spot, two staggered about for a few seconds and went down within 10-15 yards and the last one made about 30 or 40 yards IIRC.
Seven reds and two fallow have been taken between 245m and 465m, some of these I’ve posted here. One fallow ran quite far - straight downhill to deliver itself to the bike, 70m or more, brilliant planning... entirely my fault as I didn’t have enough windage for the stiffer breeze blowing further up the escarpment towards the animal’s position, and I struck it 2” behind the shoulder. That’s the furthest runner I’ve had for quite a while.
There’s been numerous goats in the 400s to mid 500s, shot from all angles from normal broadside to very steeply above and several from behind, shot through the abdomen and out through the front chest, instant death. The ELD-X just poleaxes them. In 6.5mm, a heavy for calibre ELD-X doesn’t need to be steaming along to kill effectively, it works very very well at quite modest terminal velocities.
Initially I set myself a 1800fps limit to ensure correct terminal performance. Hornady claim 1600fps but I gave myself some leeway after some discussion. I no longer concentrate so much on retained energy, it’s more about velocity of a given bullet because that is what governs the expansion and fragmentation of the bullet. As long as the bullet is expanding and fragmenting properly it has enough energy, and it will kill the animal. It will penetrate a soft skinned deer and expand fully as per design without any difficulty whatsoever at 1800fps. The ballistics say that”s a maximum range of ~675m.
To that end, a 6.5-284 is not really necessary for what I want to do at medium ranges. Its a great cartridge as long as the chambering is correct for the type of bullet you want to use, which not all of them are according to the little I’ve read about them. I think the fascination with velocity and energy is understandable, but enough velocity to get the bullet to work is... enough. A little bit more won’t make much difference at all at a given range, in fact as we know too much more can be quite detrimental to performance.
More velocity is only required when you want to go further, into the realm of proper long range, which I don’t do cos I’m not really good enough. More energy is only really required when you want to shoot a buffalo, a marauding hippo, or maybe a grizzly that’s running towards you with a keen sense of urgency! That’s why we love .375H&H, .45-70 Govt and the like. But for thin, soft skinned deers, you really don’t need a cruise missile, you need accuracy and dead drops and no need for a good dog!
Lateral is onto something with the RS60. As blokes start to experiment with the Creedmoor cartridge beyond the standard H4350 there are more and more reports of successful load development with other powders generating significantly improved velocity. I was talking this morning to my firearms dealer about returning my defective chrono and he told me about his recent exploits with the Creedmoor. He has switched to RL17, in his 24” Howa, RL17 is giving him close to 2900fps and 0.5MOA at 300m with 140gr ELD-M. I’ll be switching powder next batch, just to see what happens.
