.260 rem vs 6.5 grendel

[bm11]

So,

I have been doing a lot of research lately, and it seems that the Grendel has close to the muzzle velocity as the .260, in a smaller, lighter, less expensive package.

I don't know a ton about the caliber, but it seems to be a pretty attractive option... and makes me second guess my recent .260 purchase.

Am I missing something?

Fill me in.

Yep. Same velocity with a lighter bullet.

.260 will serve you well. Dont think you have anything to worry about.

The 260 will get an easy 300-400 fps advantage over the 6.5 Grendel, with same bullet and length barrels.

It's about like comparing the 308 Win, to the 300 WinMag.

Ok, cool. It's just that I have seen some low velocities from the gas .260's (some as low as 2550 or so, which seems crazy low) and some high velocities from the grendel (2650 with 123 Scenars.)

I guess I won't know 'til I chrono mine, it just seemed like it was getting close on paper!

My GAP AR 260 with a 22" barrel shoots the 139 Scenars at 2800FPS. No Grendel will match that or even come close.

I agree Mike. 2800 would be awesome. Mine is a GAP Ar-10 with a 24" barrel, but I will be cutting it to 20-22".

Re: .260 rem vs 6.5 grendel

I have both and love both, but two different animals. I build a lot of 6.5 grendels and have both gas gun and bolt guns in .260.

On an AR platform, one fits on a standard AR15 lower and the 260 fits on the AR10. I sell uppers for folks who can't afford a new rifle, but want to stick with their small framed AR.

If you know how to drive them, either will work well out to 1000yds.

both good rounds but completely different platforms. 260 will give more velocity every time without question. let us know how your 260 shoots.

I decided it wasn't really what I was looking for though (a long, heavy, unwieldy platform) and that with .260 I was making too many compromises by the time I chopped it down to the length I wanted (16-18") so I sold it.

I wish I could do that with mine.
2600fps is what I get from the 139 and 2850 for the 123.
Anything faster than that will blow primers.
