6.8 spc II vs 6.5 grendel for deer
« on: June 18, 2017, 04:23:53 PM »
What are you guys' thoughts?  Thinking of keeping a lookout for my son for one of these. It would be for an AR, not a bolt gun.

I have a 6.8 and love it. Its my favorite ar. I actually have a 6.8 pistol also. I have shot 3 deer with it longes one was about 205 yards. I also have shot many yotes with it longest shot on one of them was 417 yards. I dont know much about the 6.5 but have been thinking about looking into building one

Either would work just fine at standard hunting distances. I have a preference for the Grendel due to the fact of the higher BC bullets and the .264 bullet diameter. The Grendel can reach out further and shoots flatter. Which could be a plus if you want to shoot paper or steel at distance, it's also a plus for varmint hunting.

Both have huge support for components. Large selections of factory ammunition for both and both are accurate chamberings. I don't suggest it to the masses but the Grendel is a very capable chambering on big game. We have taken mule deer with it @ 496 yards and 301 yards. Along with one bull elk @ 411 yards. This was all with 16" carbine barrels.

I've also shot both chamberinging necked down to 6mm. The 6x6.8 SPC and the 6mm Grendel both chamberings shot supper well. I did shoot two mule deer with the 6x6.8 SPC both were one shot stops, both were complete pass throughs. One with a 90gr Accubond and one with a 95gr SST. Furthest one was 287 yards.

Nice rifles BH  :drool:

I love the Grendel  :twocents: Very accurate easy to reload and can shoot all day with no fatigue.

I have killed 2 Blacktail bucks with my 6.8SPC and both were DRT both were shot right at 140 & 165 yards both folded at the shot. I have a friend that loves his 6.5 as well and has taking 3 bucks now with it all were clean 1 shot kills as well...  It comes down to preference and shot placement...

OK, I'll throw a couple of parameters in...

Easy to find reloading components, especially powder.
Ammo is not crazy expensive.
Barrel 20" or less

Both have quality factory ammo for $20.00 a box and some change. Hornady dies 40.00 .

This is an interesting comparison. 

http://abesguncave.com/6-5-grendel-vs-6-8-spc-a-different-perspective/

In summary, it's a push ballistically until you get beyond deer hunting distances, especially for the west side.

I think a 12.5" 6.8 pistol shooting 85-110 grain bullets is a great choice for deer, and am building one now.  If you are OK with a 20" barrel and keep the build light, the Grendel has its advantages.

I think the Grendel has the edge past 300.

I assembled a 6.8 using a 20" ARP barrel and it shoots the 110 grain accubonds very well. Or should I say my wife shoots it very well.

This is last years deer with a 6.5 Grendel under 200yds one shot. Shooting the village bicycle.

130 accubond

Was that a heart?   :yike:  Don't want that gun, I like eating heart.....    :chuckle:

So, .264LBC is the same as the 6.5 Grendel? Is it like 5.56X45 and .223 wylde?

I like the heart too.

LBC and Grendel is essentially the same.

Just curious, why the 20" rule for the Grendel?

I have an 18" grendel and with the hornady rounds it patterns BEAUTIFULLY and I've taken a good black bear with it at probably 130 yards.

I am curious too, I have 18" grendel and love it.  Only benefit I can see is velocity, and while every bit helps, I would not say building one under 20" is a big loss or a waste of a build..

For those with experience in both, how does the recoil compare between them?  I know my 18" Grendel AR build shoots soft, about like shooting 223 AR, and it is sub MOA.  That means I can put pretty much anyone behind it and no concerns about recoil, and you can shoot it all day with no fatigue.  My 18" was not built as lightweight build but complete it was 9 or 9.5# and over 2# of that was heavy scope, the bare gun was in the 7# range.  I will get the scale out tonight and confirm..

I like the 6.5, and running something like a 129g accubond lr, it'll hammer deer out further then most should be shooting. Pretty versatle šaliber imho

There is no 20" rule, just recommendations from people who haven't tried shorter barrels. I'd always heard the same thing, until I tried a shorter barrel.

I recently built a couple 12.5" barrels in 6.5 Grendel; the ballistics are very close to 12.5" 6.8 SPC, but the Grendel's better ballistic coefficients give a small advantage even at 100 yards. The velocity difference between a 12.5" Grendel and an 18" is a lot less than I would have thought from people's comments online. Just my experience...

I've run AR Grendel's from 16" inch to 26" inch. Really like 18" inch SPR contours for a all around well handling accurate barrel. There wasn't enough speed increase from 18" to 26" on the AR to justify the weight of a AR with a 26" barrel.

26" full bull contour. Heavy!

Bighammer, that 26" is a work of art.

I went more budget oriented, and while I do not have in the environment photo's I do have a boudoir session on the red shag blanket...

How does that 18" Brownells barrel shoot with factory ammo? Let's say the Hornady 123gr A-Max or SST?
