I have these kind of arguments with myself all the time.

The long pointy bullets in the Grendel look cool.

But so does the .30 cal 180 grain round nose that go in my little 18 inch 30-30. It’s a helluva 100 yard gun that’ll punch through some pretty big stuff up close. Just enough kick to let you know it means business. And so easy to carry, and cheap to shoot.

The Grendel is surely better past 200 yards. Sure, get one if you won’t have a problem feeding it.

My other little gun aint so little. A 223 in a full size short action bolt gun.
But ammo selection is huge and not too pricy. Shoots flatter, faster, than a Grendel. So maybe better on small to medium predators at long range.
And with the advent of x-bullets, I’m not sure of the value of high BC bullets for medium game at short range.
A mini action rifle would be nice. And fit long enough bullets for me.

I guess I’d still say get the Grendel if it’ll scratch your itch.
But if you just want another lightweight, easy carrying, light kicking rifle for under 100 yards, there’s options.
