Re: 170g SST in the 8x57
My main criteria here is the absence of an exit wound and retention of the bullet shank in the deer. Accubonds tend to exit on principle which is great for sambar in the high country but dangerous for rusa in a horse paddock.

Re: 170g SST in the 8x57
I am thinking, and that can be dangerous. I may chop my 8x57 barrel to 16.5 inches. Be a bit handier with the suppresser. A more frangible bullet may be required because of the reduced velocity. May need to try a box of the 170 grain SSTs.

Re: 170g SST in the 8x57
I’ll weigh it next time I have the chargemaster switched on but it certainly pealed back past the canulure almost to where the boat tail begins

Re: 170g SST in the 8x57
Looks like what you have chosen is doing the job in the manner you need
Retained weight can be interesting, but not necessarily of vital importance. I recovered a 160g 7mm Partition from a sambar spiker recently.
Retained weight only 60% BUT entered through nearside shoulder. Shoulder absolutely stuffed - didn't even bother with a dissection.
Proceeded to create at least a 2inch entrance hole in the ribs. Through lungs. Smaller exit hole in offset ribs- maybe 1.5 inches.
Then smashed the offside ball joint, passed through the rest of the offside shoulder and pulled up hard under the thick hide.
I wasn't concerned about the loss of weight

Re: 170g SST in the 8x57
Updating this as I’ve actually got around to weighing the bullet above
57.4% weight retention at just over 100m
57.4% weight retention at just over 100m

Btw pretty sure that’s at 2850fps

Re: 170g SST in the 8x57
Hi GBE. Just wanted to revive this thread to see if you had any updated thoughts on the 8mm SST? Im finding it very difficult to get accurate info on this bullet. Would appreciate your thoughs now that you would have more experience with it.

Re: 170g SST in the 8x57
Sorry to say that I’ve probably only shot another 3 or 4 rusa with it and then switched to a .308 because of a factory round only rule where I’m currently shooting.
Do I want to go back to the 8mm? Yes indeed!
Would I point the SST at anything bigger than a red probably not. I still have a few boxes of 200g Nosler Accubonds on the shelf that need to be loaded up and pointed at either sambar or sitatunga- preferably both!- but at this stage I can’t even get them to a concrete bench.

Good luck on the big two elusive "S"s. Please give us an update on the Accubond. I am really trying to find a reliable report on them. I have had great results with 180gn ABs in a 300 mag, but when it comes to the 8mm AB, some people tell me they are great, and others that say they are too hard to expand. I looked for several years and finally manged to find a box of 8mm ABs at the beginning of the year, so I might have to go load up a few and see how they go.

Re: 170g SST in the 8x57
I’d say it’s all relative to what you load them in and what you point them at. I’d say the Accubond would be a guaranteed exit on a rusa just because of what I’ve seen them do in other calibres. I’ve also got boxes of 200 & 220g PPs for another 8mm project that has been put on the back burner by range closures. They’ll get used in Victoria eventually.

Re: 170g SST in the 8x57
Yes, the 200gn Woddleigh PPs shoot very well in my sons 325WSM. I could use the Woodleighs for a lot of stuff, but I would like a better BC and hence the reason for wanting more info on the AB. I have also had great success with the AB in 30 cal with one shot kills out to almost 500 meters. If I can get that terminal performance with the 8mm AB, I will be stoked.

Re: 170g SST in the 8x57
I used the 170 SST two years ago with great hunting success.
Using a heavy dose of CFE-223, Geco-brass, Rem 9,5m primers, COAL loaded to the crimping groove, crimped with LEE factory crimp, that load was tested more than once at the range to proof the exceptionally fine match-grade accuracy (as well as the lightning-fast muzzle-speed ...).
