Try Bergers... Once you go Berger, you'll never go back.
I shot Hornady, Barnes, Sierra, Nosler, etc... for years. Once I tried Bergers, I was sold.
I still shoot Nosler Custom Competition bullets in a couple of my target rifles because they're cheap and perform as advertised. But mostly I shoot Bergers in everything.
Im going out on a limb here and saying you probably haven't tried the eld-x......
Op, We have taken deer with the sst and that is a awesome bullet. We switched to the 143 eld x bullets in our 6.5s to see how they do. I personally would opt for the eld-x if BC is a concern if not the sst will do fine. The A-max has also served me very well.
I used to shoot the SST out of my 7 Mag; but found them to be to explosive up close. Out of my 25-06AI they were very good at dropping deer dead in their tracks. No experience with the ELD-X. I have wondered if they might be explosive up close as well.
Exact same thing that happened to me, which is why I stopped using them.
I've never had an SST fail on me. And I have shot deer at nearly point blank through the shoulders and everytime I get an exit and the deer either dies right on the spot or runs 10-15 yards. I'm not shooting a wimp load either, I am pushing the 140 at 3080fps from my .270 and this load never fails me.
