Workedfine for me in 6.5x47lap
I use 37gr rl15 and 123 scenar and got drt from skull and spine neck shots out to 135yd
Now using barnes tsx 130 but likely go back to scenars when they run out
Don't miss vitals! I have had problems with them not expanding and pin holing deer. I killed 2 with 123 scenars. One 8 pointer ran about 60 - 70 yards. The other was a piss poor shot and hit in the guts. Never recovered him, even with a hired tracking dog.
Switched to 120 amax. Killed 3 so far this season and none have run more than about 20 feet. Better shooting on my part though.
The best bullet is the one that shoots pretty good, and the one you think shoots pretty good. Then shoot pretty good and the bullet will too.
A bullet that expands soon upon impact would seem to slow sufficiently to open and enlarge the shock area and hence wound size. Rather than an entrance would without an exit, exit wounds create a better chance of a blood trail to track being two holes to leak blood, hopefully. So balance penetration with mushrooming. Any deer with a entrance hole in one shoulder and an exit hole in the other shoulder (shot placement) ain't goin too fur a piece.
The 123s lapuas seem to be very hard on deer. They leave a huge exit wound. I shot this one on the move. It did not go 15 feet after the hit. Check out the massive hole. This is the second deer shot with the 123s. Both are down with massive wound channels.
I took my buck this year with a 123gn scenar from my 6.5X47 lapua.......462 yards, it was a heart/lung hit and a massive exit hole. I'm very happy with it's performance.

I have heard better for the scenars than the smk and I believe the smk is deff more common. I have a 50/50 ratio as of now on the smk performing as desired. The swift sciracco is 100% right now with me. I havent shot anything with my 6.5x47 but have with the .260 shooting 142 SMK. 2 deer fell dead on spot and 2 ran to be trailed. The sciracco put them SOB right where they stood is where they died.
