6.5 Grendel or 6.8 SPC?

[Squid]

All the grendel I have put together have been 20 inch barrels. Average velocity is 2400 to 2500 that's with 123 grain pills keeping it super sonic further than I am going to shoot at any game. I do agree with mike if it came to 6.8 or 300 BO it would be 300 BO all day but I would keep it under 200 yards unless you are super bad ass at reading wind. Most of the blackout loads have shitty BC's and as we know if you are about to have a shot at a sweet buck in oklahoma you are also bound to have a 40 MPH wind.

Barnes 110 ttsx expands fully down to 1300 fps. That's about 350 yards out of a 16" blackout.

Yea, the BO trajectory doesn't really do anything for me. BC just sucks at those velocities and VLDs aren't an option due to mag length.

6.8 is decent since it holds more powder. Seems like with some bullets it is as good or better than a .243 at distance. Stag Arms has a reasonably priced upper with a 21.77" barrel. I wonder if I can order it without that god awful handguard and gas block? Jesse, where you at? lol

If you decide on 6.8 I would recommend taking a look at ironworks tactical. He builds with ar15performance barrels. Great stuff!

I don't remember for sure but I didn't think you gained much past an 18 inch barrel in the 6.8

 

[Wildcat]

That's correct Tony...it was designed around 16-18" barrels with faster burning powders like REL7 and AA2200

I have a a 6.8 spc for white tail. I like the round but it does have a lot of drop. I think it's excellent out to 250 yards. Anything further and it's looses it's magic

 

[Scott Hearn]

Lance, you running a 16" barrel?

Midway has a YHM upper on sale right now. Looks nice but I really want an 18" and if I go with 6.5G a 20" minimum.

Scott, have you thought about a large platform AR in 308 or 260?

Yea G.T. I have, but the last one I had when scoped was like carrying around a boat anchor. I may have to just go with a 6.5 Grendel or knock my range expectations down a notch or two. Maybe a little of both.

I have a 16" CMMG with a M4 profile barrel. It's light weight and holds MOA

I've been kicking around something to build using an AR15 platform and want to plink steel out there a few feet, what I've come up with is to get what I'm after is going to take a bit of effort and some custom dies :-O I will still be able to get the velocity to keep VLD bullets floating. Not sure it would be a good round for hunting but using lighter bullets it's not gonna be too far off of my favorite round the 243 no custom mags to mess with just a barrel and bolt. I never was a fan of either the Grendel or 6.8 but they have their place. Later,
