The 6.5 Grendel CRASHED my Enidine recoil buffer.

[Biggerhammer]

I just broke down a lower that had been used with a 6.5 Grendel upper and the Enidine carbine buffer is trashed, while still functional. The front of the main body that the contact plate recoils against is hammered so hard it is belled out a 1/8" all the way around and the lock ring for the main body front has been laying loose on the piston shaft and is mangled. That's a first for me, I'll contact Enidine in the AM and see if they will replace it. It's a 09 model but I have used it mostly with 5.56, I only ran a couple hundred rounds of factory Hornady Grendel ammo on it.

since I have a grendel coming, is this an issue with others? Or just that brand?

[Biggerhammer]

After doing some research, I have found many posts on forums of guys expiriencing the same crash/ self destruction of their carbine Enidines. Since then Spikes Tactical has come out with a non hydrologic buffer that functions the same or better than the Enidine for a third of the cost. The spikes " Heavy " buffer has great reviews, esspecialy when it comes to over gases carbine, larger calibers/ suppressed. I'm going to send mine back to Enidine and see if they will replace it. Here is a link to the Spikes buffer bellow, I'm going to order one and try it out with the 5.56 and the 6.5.

  Dang! is it just more in the carbine buffers? Or have people been seeing it in the rife buffers as well?

[JohnVH]

Im hoping since my upper is an AA built for the 6.5G that it wont have any issues, Ill keep an eye on it.

I have found it is mainly a issue with the carbine buffers.

Gotcha, I am going to be putting another one together soon. I have looked a little at 6.5 and 6.8 since I already have a 7mm-08 and then of course 223's. So I have been thinking about a different flavor. Do you have a good ballistic chart for the 6.5 and 6.8? My stuff and software is to old and does not have those cals listed.

[JohnVH]

dont know about the 6.8 now, I was looking at it but went for the 6.5 for the better everything

thanks that one does not help me to much with a 600 yard zero and such a short barrel as well.

I run the Ballistics Field Tactical Edition App by Jonathan Zdziarski on my IPhone. It's handy always with me, I can save my favorite cartridges/loads or work the shot while on the rifle in the field by entering everything I need. It will even give you the degree/ angle of the shot by laying the iPhone on a flat on your rifle for angle compensations. Very handy and well worth the 19.99, I've used it a bunch for awhile now.

That will get you the basics, real world speeds over the Chrony and a good ballistics program will seal the deal and put you on the money. The 6.8 SPC ans the 6.5 Grendel are completly different creatures and shouldn't even be campared. They were designed to serve completely different purposes, the Grendel shot side by side with the 6.8 will walk all over the 6.8 in cruise mode. The 6.8 was designed as a CQB system that's performed better than the 5.56 for close range critical one shot stops on two legged, usually bearded tango types that hang out in caves and other undesirable places. While the Grendel was designed for extended range soft target engagements/multiple target engagements to fill the nitch between the bolt rifles and the 5.56's. Unbeknown to many , the .300 Win mag is used more as a sniper platform for the long stuff than the .308 Win currently.For years the mass majority of Federal match .300 Win mag ammo was allocated to the military, for years I was hard to even get your hands on the stuff.

I just like the extra punch the Grendel packs at distance for a hunting application. 5.56's set up right are just fine for the two legged varmints out to and beond 800 meters as can be seen in the video bellow.

Im pretty pumped, Im thinking when my grendel is done I wont be using my 22-250 or mini14 anymore, we will see!

[carpsniperg2]

Yeah that is kinda why I have went to the 7mm-08 for my calling gun. A lot more ke down range then the little 223. I was getting to many runners with the 223 at 300+. So that is why I made the switch. I like the ballistics of the 6.5 after look more into it. I just don't know if I want to put a extra 400+ into my build right now. Then I will need all the extras brass bullets, dies etc. So I might just throw another 223 together. I am not sure yet, I have been all over the place in hunting down Ideas and found 2 uppers in 223 that I really like. Then I will just build my lower to match what I like and want. Most the gredels are looking around 800-1200 from what I have seen online and gun broker.
