It's been around since 2003... It was popular back then, and I remember reading about it in the magazines and wanting to build one, but never did until 2015. But the popularity kind of died-off quickly, and it pretty much went off the radar for a while, till it had another upswing in popularity that revived it. Then it sort of plateau'd and was still around, just never really took back off until the whole 6.5mm craze took off around 2010, it leveled off around there again, and now it's getting another resurge in popularity. It's doing just what most cartridges do. Everything is pretty much cyclical as far as cartridge and caliber popularity goes.I didn't realize so many people were using it!
Yes, being that the Grendel is a small capacity cartridge that's only going about 2,500-2,600 FPS, so anything over a 130 is going to drop like a hammer. It was designed to shoot 100-130 grain bullets, and most manufacturers made the 123's specifically for the Grendel (like the Nosler 123 Custom Comps), because most folks with rifles like the 6.5 CM and .260 Rem are shooting 130+ grain bullets because they have alot more horsepower than the little 6.5 Grendel does.So, is the 123gr bullet what most of y'all use in your Grendel's?
