have heard quite a few times guys didn't like the SST and switched to the ELD-M and much happier
I've only used the ELD-M, 4 seasons now and 10 head of big game in Alberta, 213 yard average shot distance and 12 yard average recovery distance, the eld-m is where it's at, very happy with this little combo
even from a short 16.1" barrel like I'm shooting now 1700 fps lands around 500 yards with a 2386 fps launch with factory hornady black ammo, I took a large whitetail doe at 420 and 1800 fps impact this year, quartering away, in middle of ribs, 1.5" exit hole after 15" penetration out inside opposite front shoulder and everything above the heart destroyed, DRT
pretty tough to get the SD or BC out of the mono-metals imo, if you're gonna play with the Grendel and maximize what those 30 grains of powder are doing then the 123gr eld-m is 'thee' bullet choice imo, we're batting 1000 over 4 seasons with it and 10 big game critters, 5 for me, 5 for my kids who are 12 and 14 now
