24" grendel sst123 muzzle 2591fps energy 1833
100 yards 2424fps. energy 1609
12.5"grendel SST123. muzzle 2210fps. energy 1334
100 yards. 2061fps. energy 1160
24" has almost 40% more energy at 100 yards
12.5" grendel is just about the same as a 16" 300 blk .
As for it being similar to the 300 blk, at the muzzle sure, but with it's high BC, you'll stay above the expansion velocity threshold (1500 fps) for 123 ssts out to 500 yards while retaining the same energy as a 357 mag at the muzzle.Last edited by sir shovelhands; 03-04-2021, 06:37 PM.
