Home Forums Hunting & Shooting AR and Tactical Rifles newbie question on the grendel/6.8

way newbie to the AR so go easy.

was wondering how the grendel case would perform on a 6mm or 25 cal platform as a deer rifle? or would the ppc case be easier in the long run?

really want to hunt with mine this year and am not a fan of 6.5(just never did anything for me). love the 25's. was thinkin' 75-100 grainers.

enough poop for killing shots at 300 yards?

dont want an ar10 so whatever i end up with will be on an ar15 lower.
TIA

I've never seen a 25 caliber for a AR platform, but then compared to many in here, I'm a newbie too, so their may be some out there. I'm sure you could get someone to build one for you but then you'd likely be working up loads from scratch. I can tell you from working with the 50 Beowulf that working up a load even partially from scratch in an AR is a bit nerve wracking, if for no other reason you do not have the indicator of bolt lift to clue you in to pressure problems. I know bolt lift is not the definitive factor in pressure guestimation, but I hate to be without any indicator when I'm exploring new territory with my sweet little face ( <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />) so close to potential disaster.

I think there are several wildcats based on the 6mm. The easiest is the .223 case necked up to 6mm. Heard lots of good things about it, particularly when deer are in the conversation and the comparison is the .223. Of course, that was before the .223 Partition and TSX's.

I'm curious and this is no flame (ever hear that before??? <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />), but why would you love the .257 and be lukewarm at best on the .264? How can .007" be a deal breaker? This particularly with the 6.5 that has won a whole bunch more matches than the 25's ever will and has had battel rifles designed around it?

I will say I was hopeful for the 6.8 after reading E4E had to say about it. It may be available in higher numbers and for more reasonable money than will be the Grendel. Still, I want the Grendel. On paper it looks like it would be a pretty handy 300 yard deer gun.............if a guy can just accept that nasty 6.5 Euro-bore <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />.

i can honestly say i have never hunted with one (6.5). i know there probably isn't a lick split of differnce between the two but that 100 grain tsx does work. also, like many here i just want something different.

the grendel seems to have won huge fans vs the 6.8 which i really haven't heard much nice to say. i haven't any experience with either so i will plead dumb.

the grendel numbers work in real world deer vernacular(sp?). i would like to see it in a 25, that about sums it up. i dont want to win matches with it or punch paper at insane ranges (i have a third upper in the works in 204). i just want a 25 in an AR that zips along at 2.5k. seems the grendel is the platform...

the pressure thing i couldn't work out in my head for sure. i could only start with a software number and work up. if i finished at similar velocities to the grendel in a lighter bullet i would be getting close, no? i am not an expert on this so homework would come first but i think it is a viable project once complete.

i am stubborn so that will cost me but i am in no hurry for it. just not warm and fuzzy yet with the voodoo rifles inards/abilities....... <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

i see that barnes is now offering a 6.5 120 tsx hmmmmmmmmmmmmmmmmmmmmmmm


woofer

.......and a 110 grain 6.8. Oh yeah, midbore AR's are comin' to a store near you! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

i am gettin' all warm and fuzzy bout' this. i think i am going to have a lot of fun.

wonder how a 25/204 or a 6mm/204 would fair? i see a few mid bore wildcats with the 223 and the 222 mag case. now that winny is making 204 brass you would not be fireforming the smaller cases to get an improved. just necksize. any idea what velocities you might see in a 70-80 6mm or a 100 25 cal on the 204 case?

I have seen a 243 on an ar platform, cant recall much about it now....

Woofer,

Remington holds the future of the 6.8 in the palm of their hands.

Currently there is no ammo to be Had on the Market from Remington.

The Grendel is interesting, and actually more common than the 6.8.

With Barret contracting for ammo being made in support of their uppers, it might very well take off IF the company contracted for the ammo maintains QA/QC to the level of the claims made.

Midway has/Had 6.8 Brass available.

If a Wildcat is to be the order of the day,look seriously at the 6.5PPC.

Magazines are available(Very important to the Magazine fussy AR!) and 7.62X39 bolts are available.

Load data is available.

Tossing spent PPC Brass into the weeds with each shot will pucker the wallet quickly however.

Remington is all set up to produce the 6.8, but they are obviously hesitating for some reason.

I share your desire to hunt Deer with the AR.
And I do have the fingers crossed.

High volume shooting with wildcats can get stressfull however!!!!!!

E-Mail Remmie daily.
Ask your friends to do the same.


As for a rifle.

Do NOT overlook P.R.I. or "Bravo Company USA".


Barret has the advertising cash.

PRI and Bravo Company quietly do as well or better (PRI provided the rifles for Remingtons R&D) and with the small makers touch of care.

Best of luck!!!!!!!!!!!!!!!

P.S.

.204/223 Ack!!!!!!!!!!!!!!!!

Am waiting on feedback for a reamer!
Have lotsa CHEAP Brass, and now available projo's.
It could get Ugly for the local crows and woodchucks!

Woofer,

Just an additional thought.

If Legal in Vermont.

.223 loaded with the Barnes "X".

Have witnessed the load run through Gelatin (Cor-Bon 53gr DPX) and through assorted barriers, and if the shot is placed properly, should be a good Bambi load.

The one Yodel Dog I shot with the DPX had an exit wound after 11" of penetration.
(She was trotting away from me and I was aiming for the back of her head when she paused.... was a smidge...er.. 80 some yards off on range estimation.)

Just in case you still have the itch come fall and no 6.8/6.5 mutant/wildcat available.


Have a bud with a Block Permit for nuisance Deer and have given him some of the DPX loads to see what happens.

When I hear about it, I'll pass it along on my home site, and pass a link to you.

P.S.

"Hello Remington? yeah, I am a disadvantaged Deer Hunter that will die thanks to a mental disorder surrounding the numbers 6 and 8, if everything in my surroundings are not balanced on those numbers.

I am non-violent and a family man with 13 Children.

Please produce the 6.8 so I can maintain my sanity and not leave my children as orphans, as my wife passed away six days andeight years ago...please..?"

e4, the only time you can hunt deer here with a 22 is at night with a flashlight <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

the more i read the grendel seems the bestest way to go. both in money and time spent. brass isn't real bad like i thought it would be and dies are a phone call away.

i still like the idea of a 25/204. any guess on velocity with a 75?

woofer

6.5 grendel and 6.5 PPC are basically(for all practical purposes) the same round. Grendel has a few slight mods but going PPC has you forming the brass off 6ppc(no big deal anyway)

Good luck! Sorry I dont' have a clue on the speed question. I hate Ruger so bad I ignore all their products and have honestly never looked into the 204 case.

I've heard that Olympic Arms is working on making uppers based on WSSM cases, specifically in 223,243, and 25 caliber. Can you imagine an ar 15 that can handle a cartridge with 25- 06 potential, hehe. This is for the AR 15 platform not the AR 10. I'd love to have one based on the wssm necked up to 6.5 mm. There is plenty to read on this topic on the ar15.com forums.
Here's a link to the topic: http://ar15.com/forums/topic.html?b=3&f=12&t=209173

Woofer,

I believea 6/204 is just the old benchrest cartridge, 6x47. Someone who knows better than me how the TCU line of cartridges might compare to your proposed series of 204 wildcats. I think the TCU were/are based on blown out 223 Rem cases, so capacity MIGHT be similar to standard 222 RM (my guess) one website has this to say about the 25 TCU:
"It is in about the same class as the old 25-35 and would be marginal for deer."

I am looking forward to the 6.8 myself, but if it was based on the 25 Rem, and the 25 Rem was based (capacity wise) on the 25-35 WCF, and I neck it down to .25, am I right back where it got started? Probably, except for better powders, and higher allowable pressures in a bolt action vs. a model 1894 in 1895.

Anyway, have fun with your project, I'm waiting for a model 7 or an ADL (whatever they call them now) in 6.8

I don't know if you guys have heard of this guys website but check this out .

I don't know of anyone who has used his stuff but it does make one think. I'm thinking of one of his 204 Ruger uppers.
