6.5 Creedmoor semiauto loads

[VKC]

I didn't see a specific thread for semi-auto 6.5 Creemdoor loads, so here goes. If possible, Please state your semi-auto platform (eg GAP-10, JP, Mega, etc), barrel length, bullet, powder and charge weight, brass and primer, and muzzle velocity at what temperature.

Okay, I’ll bite.
BRO Norguard receiver sets
21” Lilja fluted
22” Bartlein
24” Criterion
139 Scenar in Lilja and Criterion
140 AMax in Bartlein-soon to be resolved feed cone issues-feeds AMax okay.
41.5 H4350
Annealed Hornady brass, shoulders set back about .002/.0025.
CCI BR2 primers
2650-2675 at 90d, 1200’ elev.
Scenars pretty outstanding, working on AMax with large inventory of same.

 

[Niles Coyote]

22" JP barrel and guts inside a Mega Maten frame set
41.5 grains H4350 under a 140 ELD in Hornady brass with a standard CCI primer = 2670ish

 

[Saf3sh00t3r]

JP LRP-07 and Seekins SP10 6.5cm 22" Barrel each

42.3, H4350 140 ELD-M

Shoot from Temp in the 50s F to 100 F

Both produce on Average 2720 ft/s in that temp range.

Ive left my ammo in the sun by accident and get really bad swipes.

Every gun is different, so am not sure what the purpose of this thread is? not being a jerk, am just wondering the point.

Variables you asked to be defined is a good start but more importantly you need to know:
Barrel blank manufacturer
Gas system length / port location
Gas port size
Buffer weight
BCG weight
Buffer spring
Trigger (yes, it does have influence and more than most would think)

 

[Scottie15]

20" WOA 1:8 twist, rifle length gas. Slash heavy buffer, standard spring and bcg.

123 Scenar, 42.6 gr H4350, Fed 210m, hornady brass, 2790 fps. Loaded to 2.760 COAL, I think.

 

[bobke]

Scottie
Is your WOA short throated, or is there a particular reason for running at 2.76 OAL? PMags will let you approach 2.81, ASC and others to 2.85+. Scenars shoot well for you with that much jump?

 

[JimmyT]

AR 10 with PWS MK 2 lower and geissle trigger. Upper is Aero precision upper, BA 18" barrel, adjustable gas block, and lantac BCG.
Rifle is a hammer with American Eagle 140 grain BTHP and Prime 130 grain ammo.

Best reload for this rifle so far is:
Hornady brass
Berger 130 grain AR Hybrid bullet
CCI BR2 primer
42.5 grains of 4451
2.800" OACL
approximately 2650 fps out of this setup.

Round delivers sub MOA performance out of this rifle and a 24" Bergara BMP at 2750 FPS

Very happy with this combination.

 

[PorkChop]

Anyone have data for 130 ar hybrid bergers or 130 hornady eld with h4350 hornady brass.
I'm shooting out of a 22" gap 10.
Also what kind of velocity should I be expect?
Thanks

 

[GBMaryland]

Anyone got loads for a Larue OBR 6.5CM with a 22inch +2 gas system?

[Jakediesel06]

I’m curious to what the difference in the load is in a semi compared to a bolt.

 

[B y r o n]

Not sure with the newer AR style guns but guns like the Garand and M1A's hotter loads tended to beat up the actions from extra force. Bolt guns didn't have this problem until you got into over pressure loads which are bad for any gun.

I worked up 130ELDM with Varget and H4350. Varget was best. 22" JP barrel. 40gr, 2.835"COAL, CCI primer, 2851fps at 60F with SD of 10.8fps. It was a lazer till about 600, then the bullets inferiority shows up. It falls a mil short of its G7 BC at 1000yds and is horrible in wind. Dont waste your time. go 130Hybrid or 140hybrid/eldm.

[LG65CM]

Rock River Arms 20" bbl, 6.5mm CM: Hornady 1XF brass, trimmed to 1.918", Federal 210 primer, Hornady 140 HPBT bullet , 44 grains of Superformance powder. COAL 2.80". Upper 2600s MV. Easily less than 1 MOA @ 100 yds. Get same results using this load in my RPR.

 

[223762]

Dpms in 6.5 cm. 22” Bartlein gain twist barrel. Hornady 140 ELD Match 42 grn of H4350 Hornady brass federal 210m or cci 200 primers. Not sure on velocity, but if I had to guess 2625 to 2650 range. Here’s 2 pics, one from 800 yds and then 900 yds

 

[lennyo3034]

24" Bartlien rifle +2 gas system.

41.2 grains of H4350 and 140 ELDm.
2720 fps

Factory Hornady ELDm gets me the exact same velocity and POI. Very easy shooting load, no pressure signs at all. Ran without a hiccup on a hot match. I've taken it al 42.0 without pressure signs but had better accuracy at 41.2 and thought it would be nice to match factory ammo.

 

[wildcats]

Lmt mws 6.5 CM with 1-9 twist.
anybody have a loads for the 120 ELD-M and Scenar 123s ?

How horrible is horrible? Looking at a 130gr based 65 build so gathering real world experience. Thnx.

Here in Europe we shoot 123 Scenars out of 20” Krieger 1/8 with 39,5 gr of VV N150 in Hornady brass at 2790fps single digit SD. Same results with 38 gr. In Peterson’s. Easy half MOA at 100m.
You should achieve same results there with almost the same recipe but with Varget instead.

 

[memilanuk]

@gnatmm good to know... I have a *bunch* of N150 (40+ lbs) and it'd be nice to have it work in my 6.5CM

 

[Txmxracer]

Has anyone used 4831 in a 6.5 gas gun?

Hornadys g7 vs litz custom curve differ by about a MIL at 1000 yds for the 130 eldm. Beyond 600 hornady black works better. And my impacts matched the custom litz curve which is worse in the wind than hornady black.
Berger 130Hybrid or 140hybrid/ 140 eldm are fine.140 hybrids are too long for Ar10 magazines. Sierra and others have interesting 130 options that I have not tried.

Should be too slow. Expect poor velocity and compressed loads. You will have to turn your gas down.

 

[Txmxracer]

Kinda,what I was thinking. Thanks

 

[lennyo3034]

I've tried and these were my exact results. Stuck to H4350.

 

[Caterpillardoc]

42 grains H4350
140 ELDM
Starline SRP cases
CCI 450
Seated to 2.800”

I use this load in an Aero AR308 with 22” Ballistic Advantage barrel, runs 2717 FPS and a 26” Criterion barrel on a bolt gun that runs 2811 FPS. Both rifles shoot great with the same load, much easier since will work in either.

 

[rggianfranco]

Hi everyone, my AR is in 6.5 creedmore, it has a Lothar Walther match 24 inch barrel, Precision Armament compensator, Vortex diamonback optics with a high performance, 37 grain Viathavouri N 150 ammunition and a 140 grain smk.
At 100 meters 5 shots in 1.5 centimeters and at 300 meters 5 shots in 4 cm, we will see whether to increase the dose for 1000 meters.

 

[Perchowski]

JP LRP-07 clone with a Juggernaut tactical 80% lower/matching upper. Only difference is I run mine suppressed with an Omega 300 so I went with the JP VMOS BCG and their H3 SCS to prevent premature unlocking of the bolt.
Load is 42.3gr. H4350
Norma brass
CCI #34
140gr. Barnes match burners
Seated to ~2.785 ±.007 (ogive varies)
Lee crimp die

With no crimp I'm pushing them 2750fps, crimped they're at 2800fps.
Shoots under MOA @ 600yds.
