hey guys, wanna hook me up with some load data?

i will be using Lapua brass and Redding type S bushing comp dies. these are the only components i have settled on. i want to use Berger VLD bullets (140 grain) and Sierra Match Kings in 140 or 142 grain.

i will probably use a 1-8" twist barrel.

whatchya go fer me?

Yup on the 8 twist and skip the 140 Sierra's. Let your gun decide on the other two.

Just buy a load of H-4831-SC, same lot, and don't fritter away your barrel looking for the holy grail.

I know one guy loading for this cartridge, and he has been very happy with the max load for 140gr bullets and MRP-2 (for more than 2900fps) found on Norma's Reloading Page

I post a link so I do not have to worry about typing! smile

56g H1000 with 140g Berger VLD for 2950 fps or so was the ticket when I had my 6.5x284 barrel. Max for me with H1000 was 58g.

Curious to hear more about this load?

Bullet, velocity, accuracy, etc..

LD,

Longrange target shooting or hunting? For hunting I'd stick with the Bergers (if you can find them). Are you using a short or long action?

One of my favorite loads in my LA REM700 is 51.0 gr of RL17 (MAX in my rifle) with the Bergers seated out to a COAL of 3.18".
I have had 1/2 MOA accuracy with this load jumping the bullet .020"-.030". Velocity averages 3030-3050 fps out of my 24" Douglas barrel (1-8" twist).

I've also gotten similar results with accuracy and velocity with 61.0 gr of MAGPRO (also MAX in my rifle).

If you are looking for a longrange deer/antelope hunting load be sure to check out the 120gr Ballistic Tips. Not quite as high B.C. but they shoot LIGHTS-OUT in my rifle (1/4 MOA).

Whatever you choose have fun and be prepared to spend a lot of money on reloading components b/c there are a ton of choices and the cartridge is a joy to load for and shoot.


It ain't what you don't know that makes you an idiot...it's what you know for certain, that just ain't so...

I am building on a long action and it will be for shooting steel and hunting. The plan is to shoot the Berger 140 hunting bullet.

4135sc and RL 17 was the only powders I was going to try. I have read some reports of up to 200fps gain with the RL17?

I have a custom 6.5-284, Pre-64 M-70, Jewell trigger, blueprinted with Bordens bumps and a 26" Kreiger heavy 8.5 twist sporter bbl in Boyd's, Jon Sundra laminated stock, glassed, free floated and pillar bedded. My best accuracy with 140 gr. SST's and 52.3 gr. Vv 165, is a .174" three shot group at 100 yds. Shot a .200" 3 shot group with 140 gr. Berger VLD's, .050 jump, same powder charge.

Tried RL-17 for the advertised extra velocity. Best accuracy/velocity combo was 48.8 gr, which consistently chrono'ed over 3,000 with 1/2" groups and good SD's. Over 49 gr., groups opened up and at 49.5, was shooting 1 1/2". The Vv 165 load chrono's at 2,950, so the RL-17 doesn't give me a 200 fps premium, only 50-75 fps and 1/2" groups, no teens or twos. Probably stick with Vv 165.

SST's devastating on Pronghorns and Whitetails. No report on Bergers, yet.

Don't automatically assume that you will be shooting that bullet unless you have at least a #7 contour barrel. You may have to try some other bullets. Having shot thousands of rounds in 1000 yd competition with that caliber, I have had occasion to try lots of stuff. I quit shooting it before some of the boutique powders and bullets were out but last year built another.

I have equally good luck with 140 Amax, 140 Berger and 142 Sierra in competition. Now I use 130 Norma Diamond Line and 108 Lapua Scenars. If I were to hunt elk with it, I would use something else. I like R17 and H4831. I also like H4350 with the 108s. They make a great 700 yd coyote round!

I have a few boxes of 130 and 140 Accubonds but have yet to shoot them. Might be the better bullets for elk. I had a hunter shoot a very large bodied bull elk last week with a 7mm Rem Mag and a 140 or 150 Accubond and it did real well. I suspect the 140 Accubond out of the 6.5 would fair equally well.

I prefer the 8.5 twist to the 8" twist as I can usually get at least a 50 fps higher "sweet spot" with the slower twist- sometimes 100 fps. For hunting, this is nice. An 8.5 twist will stabilize every bullet I have ever tried. Some I haven't tried are the 147 Cautarucios and 160 Akers.

Dennisinaz,

Appreciate your info. I'm now working on Berger 140's for hunting. I did the Berger suggestion on optimal jump,
shooting three shot groups at .01, .05, .09, and .13 jump. Seemed that I had my best groups at .05, and .13. I decided to do a "jump ladder" from the idea of a powder progression ladder, looking for clusters. Problem, you have to account for each bullet for it to work. I shot at 200 yds, hoping for more spread to make it easier to tell what was going on. I loaded from .01 to .18 in .01 increments all with my best Vv 165 load. Many were hitting so close, the 80X spotting scope couldn't differentiate. Made a bunch of 4 wheeler trips to the target. Bottom line, had two clusters, around .05 and around .13. Currious as to why two clusters and which one to use. At least the data appears reproduceable.

Any ideas or suggestions?

Does anybody else find it amazing what a disparity there is in the load data for this cartridge??

It doesn't seem like the case capacity difference between the 6.5-284 Win (short throat) and Norma would make such a big difference... take for instance the Nosler 130 info vs. the Hodgdon 129 gr info for IMR-4350; 50 gr max for the former, 45.9 gr max for the latter. And the NAB used in the former info is typically "stickier" than the 129 gr Interlock used in the latter... weird.

In looking over the Hodgdon data Hybrid 100V caught my eye as being a constistent top performer in the cartridge, yet I see no no mention of it anywhere. Is this another anomoly that can be chalked up to the difference between the Win & Norma iterations of the cartridge?

I'm with dennis... that 107 gr SMK at a high rate of speed seems to me like an insanely awesome 'yote killer!

I'm working something up for 129 gr SSTs. My Savage 112 BVSS has a long action and "Norma" throat. I've got H4831SC & RL-17 & intend to purchase (due to the preferences of other rifles) some IMR-4350 & RL-19... anyone have any suggestions? Anyone have numbers for 129s/130s and RL-17?

Also, has anyone tried Ramshot Magnum in this cartridge at all?

Any assistance would be greatly appreciated.

Great discussion all! Merry Christmas!

Are you getting cratered primers. Mine were cratering before 2900 fps. Can't imagine what they look like at 3000 fps. Norma brass shooting 142 SMK. 12F Savage 8x32 NF[Linked Image]

I've had 8 and 8 1/2's and haven't seen a velocity advantage with the slower. My go to load was H-4831-SC at 3060 with the 142's in 30" tubes. Primer pockets still holding after a dozen firings. 140 VLD's seem to prefer 3 grains less at 2950 or so. All moly, all hard in the lands.

Do you gentlemen use magnum primers? I've noticed that a lot of load info is... I thought that was weird for non-ball powder loads in an '06-sized case?

Oh... 210 M is Match not Magnum!

Thanks for that clarification...

mine loaded with the match grade. Savage must have a sloppy firing pin to crater like that at lower speeds than other models. Anyway I live with craters and leave them cruise around 2900fps -142 smk. Very accurate round. We were shooting pop cans at 425 yds straight out the box with this rifle. They won't go through a 1/4 inch steel plate. The bullets blow up on contact.
