Mid asian ibex - cartridge choice

[best defense]

After many years of planning, it looks I will finally make it to Tajikistan to hunt mid asian Ibex. I am looking for advice, out of my 3 suitable rifles, which one should I take?
APR 7 SAUM (love it, but if ammo is lost, you are not getting it in Tajikistan)
Blaser R8 300 weatherby. Accurate but a bit heavy.
Sako S20 6.5 creed. I shoot this one the best but i am not sure if it is enough gun (143 hornady eldx factory ammo)

i would try to keep my shots 500 yds.
What would you take?
Thank you!

Go with the Sako. It is plenty of gun for an Ibex if you do your part. Aim for the top of the shoulder and try to take out the spine.

Beautiful Trophy and it sounds like a great hunt. I am glad it all worked out for you and want you to know I am very Jealous!

Thank you for all the kind lines. Without going into much detail, it was certainly not a cheap hunt, but it was less than half the cost of guided elk hunt these days, including airfare. Admittedly though, I'm yet to kil a bull elk, but I keep trying to get it down unguided….
