Lots. I have 2 6.8 and a 1-8 270 wsm. I also own my own property and hunt and shoot a lot. The 170 berger is a hammer and has a similar bc to the 156 berger I can say it drops game much more dramatically them the 140 berger 6.5, at least out of the creedmoor which I have also used a bit. So did the 7mm /168 out of 7mm wsm. I also dont stick with one bullet type as try many in many different cartridges as I like to test things. I have killed game with 165 matrix, 165 ablr, 170 btip, 170 berger, 175 tgk in last few years and that is multiple of each except the 170 btip which is only 1 so far. I have about 250 170 bergers left on hand since you asked
The reality from your posts Form is you are stuck on eldms as being the best game bullet and will dismiss anything that does not use that bullet. It is a nice bullet but it is not a hunting bullet. All of the hunting heavy 7mm/6.5 bullets are similar bc to heavy .277 cal. There is no magic. And you are right the 6.8 does not do anything the 6.5/7 prc do not. However it does more than 6.5 prc and nearly as much as the 7 prc. Whether there ends up being market there or not is tbd but if you want more performance/heavier bullets than a 6.5 prc but not the recoil of a 7prc/300 mag get the 6.8W.
You folks keep dissing the 270 wsm but it was no different than the prcs. It came out and everybody made ammo for it and chambered it. The Jamison lawsuit and royalty derailed it some but it is still well supported. The RS darling Tikka still chambers for it let alone Win, Browning, Savage, CA (probably others)and I have recently seen Win, Horn, Barnes, and Nosler ammo for it. Both Peterson and ADG making brass for it this year. Not bad for a dead cartridge. How’s that 300/338 rcm support? So, when you think you are a prognosticator at least look outside of your small world. There are a lot of 27 cal fans who like the balance it offers for hunting…
