6.5 Creedmoor

[misser]

Most people just reload to control all aspects of accuracy and hand select components. Sounds like you're doing things the hard way for little to no benefit.

control all aspects of accuracy ?? humm .
do good lots, that is to say lots that are much closer to the same dimensions from one to another lot number ,do anything for you? just by chance I found two different lot numbers that are over 20 thousands different . Would I quibblo about 5 thousands difference or would I just show you's that these two lot numbers are only off by 5 thousands difference .

I can appreciate the fact that if nobody knows what you're doing they can't say you're doing it wrong. You say .020" but .020" of what? OAL? What about all the other influential variables like charge weight by tenths of a grain, neck tension, distance to lands, flash hole uniformity and so on. Hand loading my COAL is usually within .0015". Maybe it's just me but breaking down factory ammo to fine tune charge weight just doesn't seem worthwhile. Hornady 140 match had a SD of 11 in my gun and I can't imagine doing better by taking them apart before hand.

do you play left out...... i'm measuring a bullet, never said cartridge

So used hybrid 100V with Peterson virgin brass, Remington bench rest primer 7 1/2 seated to the lands with Sierra 140 BTHP gave me an average of 2720fps with 40.0gr and less than a half inch grouping.

If you are running 153’s and H4350. What’s your charge weight and velocity?

 

[Rob01]

I’m using 153 ATips and not the Bergers but using 40.6grns and getting 2680fps area with my 28” barrel.

Wow! Seems like 6.5 Creedmoor has lost some of the popularity it once had. No one has posted anything on this thread in the past 18 days.
Just an observation.

Well, lots of people are playing around with all these new magic chamberings and starting over. 6.5CM is pretty much figured out except for what is going to be barrel or gun specific. I bought my first 6.5CM about 2 months ago so I'm still working things up.

LOL! Come to think of it, that's where I should be!!

 

[MrMcCrackin]

i still need to buy projo's, just dragging my feet until i absolutely have to

 

[dukecola]

Um, I shot a Coyote silhouette target at 1120yrs today with my 6.5. Wind was changing direction, variable at 10mph. I'm drinking a brew right now to celebrate.

Got my G3 Razor back from warranty work. Need to remount/zero it. Then I'll load some ammo.

Alpha, BR4s, 41.5 H4350, 140 hybrids seated to mag length of an AW mag. My PVA barrel likes it.

Hey all! I'm not new to reloading but new to the 6.5CM.

No chrono so I use OCW method for developing a round in two rifles, 24" Howa 1500 heavy barrel in a Trybe chassis and 1st gen Ruger Precision Rifle. Both sporting Vortex 5-25x56 scopes and Vortex precision rings. RPR is more comfortable to get behind but the Howa trigger is better hands down.

I run 3 shot groups in 0.2.- 0.3gr increments up to recommended max charge, find nodes and repeat with 0.1gr increments two below and above node. I have not messed with seating dept too much as projectiles I have used will not fit in mags with .002" bump. Groups measured with Ballistic-X app.

Starline new, CCI 250, 39.0gr N160, 140gr Barnes MB (max AICS mag length)
HOWA: 0.47 - 0.60 repeatable moa at 100 and 200
RPR: 0.51 - 0.83 repeatable moa at 100 and 200

Starline new, CCI 250, 40.3gr SW4350, 143 ELD-X (max AICS mag length)
HOWA: 0.51 - 0.57 very consistent moa at 200 (6x3rd groups)
RPR: untested

Yessir. And I've got another 6.5 CM barrel waiting, didn't choose a sporty 6 to replace the current 6.5 CM.

Wanted to share a successful load i'm having with my MPA barrel

26" Barrel
Berger 140 HT
Lapua SRP brass
CCI 450 Magnum Primers
40.4gr H4350
COAL is ~2.960" (MDT no binder mag max)
5 Shot group data

Avg FPS 2756
ES 24.3
SD 8
Mean Radius 0.124 MOA
Group Size 0.361 MOA

Was running the same load with large rifle brass with BR2s and switching to the CCI 450s improved things for me, lost about 15 FPS

Hoping this helps someone for heavy bullets, there is some info out there but not a lot on the Berger 156 gr EOL in 6.5 creedmoor. Goal is to make power factor (which it does easily).
Powder: H4350
Brass: Lapua virgin SRP
Primer: CCI450

Platforms: 1) Accuracy international AX308 MC M27 Short action 24" Bartlein 8 twist by the one and only Robert Graduous 500 rounds on it prior to load workup SRS Ti Pro 4 muzzle brake 2) Impact NBK w/ a proof Lone Peak prefit carbon 24" 8 twist 1350 rounds on it before load development (headspace perfectly and fired dimensions are near identical to all of my other 6.5 CM barrels I've owned) MDT CRBN stock, TMB tuner brake 6.5mm.

Ladder, seated 0.02" jump on the AIAX, 0.045" on the proof Impact/LP (which is 2.945 COAL for both) b/c of throat erosion likely

What is crazy is the AIAX ladder shots were touching into the same hole but was .5" wide, I couldn't believe it given the velocity dispersion but demonstrates the accuracy of the AI platform, and how you can't rely just on group size at 100yd for long range consistency. I did not have any pressure signs on this test, 75 degrees at 4500 ft elevation.

AIAX: 41gr initially had the best group and SD/ES 2680 fps average, SD 5, ES 9, 3 shot group .211 MOA ; but, after going out for a seating depth test 41gr was much hotter and had heavy bolt lift at 2730 fps, so pulled the remainder of the rounds and backed it down to 40gr and one load at 39.5gr which all absolutely hammered! Bore scope did NOT reveal any carbon rings in neck of the chamber or in front of the lands. SD and ES on 40gr weren't the best however.... 39.5 though is great at 0.190 MOA seated .02" off the lands.

Impact NBK LP (lone peak) proof factory prefit carbon 24" 8 twist: Went w/ 40gr based on ladder satterlee test, w/ exception of 2 outliers the SD and ES's of this 40gr charge was great at 2603 fps average. Accuracy was pretty solid too seated at 0.045" 0.306 MOA, and .075" off lands at .203 MOA, using the TMB tuner brake at 0 setting. What worries me is the migrating 3 shot group could have been the nightforce NX8 4-32 but I had dialed out ALL of the parallax, hopefully its not the MDT CRBN stock which is not bedded but installed the impact correctly. I had a .03" seating depth off the lands that opened up to .643 MOA but I think this was me b/c I'm not used to shooting a fairy light gun.

As always workup slow and use this info at your risk. Everyone's powder lot is different and I'm shooting at 4500 ft elevation.
