Factory ammo comparison

Hornady 6.5 Grendel 123 gr vs Hornady 100 gr btsp whitetail special.

Muzzle velocity 2580 Grendel, 2960 for .243
Muzzle energy 1818 Grendel, 1945 for .243

If using 1000 ft/lbs minimum impact energy rule the Grendel hits that at 400 yards, the .243 at 375 yards.

If using say 1600 fps minimum impact velocity rule then the Grendel hits that at 625 yards and the .243 at 650 yards.

Grendel b.c. .506, s.d. .252
100gr .243 b.c. .405, s.d. .242

The Grendel burns 25-30 grains of powder, the .243 40-50 grains.

Typical barrel life Grendel 5000+, .243 win 1500-2900

Most people wouldn't think to compare these cartridges but when the math is done they compare really well, nearly identical. They are both great choices, one just a lot more efficient for the the powder it burns.

Pretty hard to ignore those numbers imo. And it's not like it's a new cartridge, just new to Alberta's fan base. It's been killing quite reliably for many years now.

So say you're shopping for a lighter hitter, for whatever reason, and considering a .243 as so many of us do, have, will. And you remove the headstamps, koolaid flavor of the month etc. and look at only the data and you see the above.....you're going to choose the .243 win??? If pbr is really important to you then sure, otherwise i'm not seeing where the .243 bests the Grendel?

Grab your popcorn and chew on that.
