AR Style 6.8 SPC or 6.5 Grendel?

[shyfireman]

Wanting to build a new AR in either 6.8 SPC or 6.5 Grendel. Looking for input from those who know best. Looking to use it for a mid-range deer and pig rifle. Thanks

If you haven't had a chance try doing a little googling or searching here as it has been discussed a few times in the past.

With that said I made the decision to go 6.5g because it shoots flatter, but alot of people swear by the 6.8spc.

for the 6.5 sierra infinity says 120 gr. Nosler ballistic tip SP, supersonic too 1055 yds @2500 fps MV, 1078 ft/lb @300 yards.

6.8, 115 gr. Sierra MK supersonic to 705 yds @2600 fps MV, 923 ft/lb @300 yards.

6.8 for hunting or a 6.5 for target shooting. I have two 6.8s but lust for a 6.5 (I'm a target shooter).

Thanx, Russ

Midrange either will do fine; I went with 6.5 Grendel.

I went with the 6.8x43mm SPC.

Grendel

dont try this with 6.8 at 550 yards

For short to mid range hunting either will do. For long range, choose Grendel.

I like the 6.8 for hunting and mid/range shooting.

I love my 6.8 AR. Yeah if you wanna be shooting long-range, then the 6.5G is for you, but mid - short-range, I like the 6.8SPC. It's a hell of a fun gun to shoot!

Define mid-range.
Everyone's definition is different.
I prefer to use the NRA definitions for the different types of rifle matches.

Short range: 200yds and closer.
Mid range: 300yds to 600yds.
Long range: 800yds to 1200yds.

The distances between 200 and 300 would be short to mid.
The distances between 600 and 800 would be mid to long.

Im thinking more along the lines of 300-600. I also want the power in case I go beyond that. I havent checked into what either caliber is going to cost either. I think they are about the same comparably. Im also curious as to what the more popular is right now in for the simplicity of parts and ammo. I read some old threads on here that were posted around 2007 and people were talking that the military will not go with the 6.8, therefore mil-spec designs will not be there... right? I suppose this is correct in regards to the 6.5 but... The idea originally was an AR-10 but the cost is enormous and i was being told that the military is finding that the performance of the 6.8 is better if not the same as the 308.

.....6.8 is better if not the same as the 308.....

Woah woah woah.....no.

I suspect you have not spent much time in the field.
Do you realize how far 300yds is?

Most in-experienced people will double or triple range estimations.
The stop sign at the end of my street is 100yds from my garage.
When I have customers over and we start talking about range estimation, most people will estimate the range at 200yds or more.



I would be willing to bet that your estimation of needing to shoot to 300-600 yds realistically translates into 75 to 250yds.
I have been at the range many times when people put targets up at 50yds and thinking they are shooting at 100yds.

If you want an eye-opening experience, buy a laser rangefinder.
Drive around with it.
Every time you are at a signal, start ranging things and note the distances.
Then start walking around in the field and range things with it.
You should do this when you are scouting a potential hunting area.

Not my quote... This was coming from a buddy who is saying the military is going away from the AR-10 in the 308 obviously and looking at making the 6.8 the round of choice. From what Im understanding, that doesnt make much sense as the 6.8 seems to be more of a short to mid range round.

I completely agree with your opinion. I wouldnt say Ive spent a lot of time, a fair amount and enough to the know the difference between 100 and 200 yards. Yardage was a real eye opener when I started hunting out of state in Idaho and Montana so with that I did do what you had recommended. I have a Leupold Range Finder that goes out to 1000 yards. Most of my shots out of state have been between 300-400 yards with either a Remington 7 Mag or 300 WSM, but distance is nice out of state. California is a different story. Shots usually around 75-200 yards if that. I spend about 3 hours every other weekend working on shooting, typically milling targets to about 300, but thats with a bolt action. Im no expect, but if I am going to spend the money on another AR, Id like something with distance as well as punch at that distance. Nice range by the way. Wish I had area to play with like that on a daily basis.
