Gamechanger bullets on game?

Justahunter has

Yes. The .264 130 grainers worked pretty well for me on a couple of antelope. Killed about as well as anything else I've ever used which was mostly Hornady 129 gr interlocks in a 6.5-06 and/or the 6.5-06AI. I plan to use them again.

Any more reports on this bullet?
Is it just a quite fragile, much like the Hornady SST?

Its a long range bullet, probably pretty soft at close range, as is the trend with long range shooting...but no doubt they will kill deer and pronghorn, about any decent bullet works on them. I don't care for soft bullets like the Nosler Balistic tips, they ruin too much meat up close and more deer shoot up close than out yonder..Ive had good luck with acccubonds up close and out yonder, its a good all around bullet..
