Nosler 6.5 140 Custom Comp Bullets

[Shane Roya]

I posted this on a 6.5 Creed site and all I have gotten for feed back is You are over pressure shooting those speeds.

Has anyone here had any experience with the Nosler 140 CC in 6.5 rifles, 260, 6.5x47, 6.5-284 or other 6.5.? Target results real world BC results? I have only found older posts relating to Nosler CC

They are not a high BC bullet but no reason they won't work well out to 1000 yards and for my intended purpose should be great.

My Post Read:
"I ordered a box of 1000 factory over-run 140 gr Nosler Custom Competition Bullets (not blemished) to use in my 2 6.5 Creedmoors.
I liked the price (only $207 for the box) and I wanted a bullet I could use for low end velocity 200 yard egg shoots or just 100 yard shooting. It looks like I should be able to find 2 nodes between 2600 fps and 2850 fps with H4350, RL16 and RL26. There should be one more node at around 3000 fps with RL26 with the 24" 10 BA Stealth, add about 50 fps to those figures for the 26" Savage build.
Will test with BR2, GM210M and GM215M primers using Nosler Brass."


I already know that the highest node is at the limits of 6.5 Creedmoor Pressure, I have run many other bullets up to that point, not my first Rodeo. Funny thing is the info given above is not enough for any one to make an over pressure statement. Unless they new all load data I will be using they are only talking out of their Donkey Hole.

I shot many of them years ago. They will work fine for your 100-200yd uses. I just found that the 142 smk shot more consistent out of my 260 for 1000yd uses.

I have a supply of the Nosler CCs and I use them like you intend to. I find that they are very jump-tolerant, preferring to be away from the lands a good bit in my 6.5 barrels. Given their profile, it will eat into case capacity to some degree but I don't push them hard.

They do just fine for short to mid range. Try 'em well off the lands (.020 or so) and they're likely to shoot pretty well for you.

Thanks for replies, it looks like the upper node I usually get with 140 bullets and RL26 may not work because of case capacity, if my 2 Creeds don't like it close to lands. That will be fine I already have loads with 147 ELD-M and 143 ELD-X that shoot well at upper end with the 26" and 24" barrels. My main concern is reducing 200 yard groups in half, so if I do screw up I may still be within the EGG.

Tested out the Nosler 140 Custom Comps today kept temps above 70 degrees so it will be easier when summer comes around.

I loaded to 2.740" COAL (.020" off lands) using Nosler Brass Collet Neck Sized 52.7 gr H2O capacity. Used RL26 powder, BR2 primers and all bullets were HBN coated. 5 shot averages
Rifle 10BA Stealth 6.5 CM 24" Barrel
Grains Average velocity SD
46 2745 fps 17
46.5 2783 fps 6
47 2816 fps 18
47.5 2848 fps 8
48 2894 fps 5
48.5 2926 fps 12
49 2964 fps 8
49.5 3001 fps 11
Everything ran very close with projected QL data, highest load was at Max CIP for 6.5 CM according to QL for my Rifle, I do not recommend loading that high without slowly working up.
The 49.5 gr load looked like it was just moving out of the node, will know after tests without MagnetoSpeed installed. I just don't think from what I see I will be able to use it. Too close on upper pressure as well I think 48 through 49 gr will work for me some where withinn that range. Once I have a better handle on it I will change seating depths.
No visible sign of pressure, easy bolt lift, tight primers, no flattened primers 49.5 was just barely less rounded than the 46 I started with. Definitely way less noticeable pressure than with Hornady Factory 140 ELD-M Loads.
I tested velocity with my MagnetoSpeed, will now do an OCW without it installed. The Stealth is more effected by the MagnetoSpeed than my 26" Heavy Palma Barrel is.
I am also testing out a few (10 each) for effects of Full length Sizing, Bump Die and Collet Neck sizing as well as Body Die and Collet Neck sizing. I am using the 48.5 gr load above for the 3 different sizing methods. Will check Velocity and SD.
I checked for bullet Run Out on each type with the 10 loads each. The results were:
Full Sized with Forster Die was the best with .0005" to .0015" with the majority .001" or below.
Body Size with Redding Die and Lee Collet Neck die ran .0005" to .0015" with the majority between .001" and .0015"
Lee Collet and Forster Shoulder Bump was .005" to .0015" majority were .003" and down.
Not a lot of difference with full length and Body size Collet Neck size, but just Neck sizing does leave a bigger variance.
