Recently I made up a 26" 6.5x284. I have tried three types of bullets all 140gr. Namely Hornady, Nosler Accybonds and Speer Hot core.
They all shoot pretty good but not super.
With lower velocity about 2800 the Hornady shoot three shot into a 1/2" using Relo 22.
Near 3000 it starts stringing.

I started with Reloder 22, but ran out of that powder and could not find anymore. Max load 54.0gr with e the hornady and the Nosler.

The Nosler did not shoot very well in my 8.5" twist. I cut the pastic tip off and they grouped 3/4" at 100. I don't think this is a good idea because it may have a too rapid expansion?

This is the first time I had any experience with a 6.5.

The Speer 140gr and 54.5gr H4831SC shot very good too about 3/4" at 100. I also have a can of H4350, but have not tried it yet.
Thinking I may try the 130gr TSX but this bullet is also very long and may not stabilize.
The 100gr TSX in my 25-06 is deadly accurate and kills with authority on deer and Antelope.

I don't know which 6.5 bullet will be best for long range hunting up to 450yrds mostly WtDeer and Mulie or maybe a moose or elk. Any ideas would be very helpful.

I`d go with 120/130 gr bullets for deer. When you get into moose I still would stay with the 125-130gr wgts but a premium bullet like the TSX or Partition as my choice.
I`ve had real good luck on deer with 129 gr Hornadies in both the 260 and 6.5x55. They act more like 140 gr then one would expect, and are accurate to boot in my rifles.

Ole Joe.
Yhanks for the reply. I will give the 130gr a try.

I think about 2950FPS is the magic number for the 6.5X284.

Mine likes --140 Bergers and SMK's with Hybrid 100V, 49ish grains and 210GM's.



(Always start 5 to 8% low and work-up)

Butch.
During my load development I got the best accuracy at2935ft with Reloder 22. But I ran out of that powder and now using H4831sc. My results are nearly the same with 140gr Speer Hot Core and 140gr Horn. SP. Near 3000ft accuracy is diminishing. 2950ft is a good number.

I think either one of these bullets will be ok for huntig deer and Moose.

Thank you every body for your input

Fred M.

Zermel, go to 6mmbr.com, it has alot of info on the 6.5 x 284. AS in AR, great source for load info.If you are seeking max vel, I think RL 17 is the new "go to" powder for the 6.5 x 284.

Never seen Reloder 17. Yes i know about the 6mmBr.com. I bought the two powder that the
1000yrd shooters use H4831 and H4350. I already bought $150 or more components.

Alliant powders are not always easy to get around here.

I shoot a 260ai & like compressed loads of IMR7828 for my best results w/ 140gr bullets. I would try it in a 6.5x284 as well. It has proven more uniform than RL22 for me & gives me highest vel. w/ exc. accuracy.
For hunting bulllet, I find the Speer very soft. The Hornady should be a bit better but for high vel impact, you might try the 130grNAB or 140grNP.

Neither of these two bullets are available here
Who makes the NAB and the NB

The big N stands for Nosler.
NP-Nosler partition
NBT-Nosler balistic tip
NAB-Nosler accubond
I use the BT for varmints and the NP and NAB for bid game.

Sorry, the NAB is Nosler AccuBond, the NP is Nosler partition. What bullets do you have available? The 6.5x284 can stress a std. cup.core bullet @ shorter range impact vel.

Fredj338
Ah, these abreveation can be confusing. I tried the Accubonds 140 they did not group well. Not enough twist @ 1-8.5. These bullets are very long at 1.390" and need another 200ft to stabilize, me thinks?

So I cut the plastic tips off on a few and they produced 3/4" groups at 100yrd at 2940ft with the new length of 1.228". I don't know what that bobbed tip would do on game? The metplat is now 0.132", pretty flat nosed. Quite sure it wont shoot as flat as the regular tip.

The Nosler Partition 140 I have not tried as yet, I don't think I need them for deer but they shoot weel in my 7x57 #1 AB.

Thanks

i like the 140 hornady a-max. works well on deer.

I had thought of them but on the box it says
a 1-7.5 twist is required my rifle ha a 1-8.5"
twist.

Like I said above about the 140gr Accubonds which are about the same length, would not shoot very well until I cut the plastic tips off.

Fred,
I'm confused as to how cutting the tips helped. I believe twist rate has as much to do with bearing surface as total length.

Its metaphysical

The bullet length has a lot to do with gyroscopic stability. As you know the greater the bearing surface the shorter the bullet gets
in equal weights. A 140gr RN is one heck of a lot shorter than a 140gr VLD.

All I can say, that when I cut off the plastic tips I got good groups. All my stability formulas include the length of the bullet. The longer the bullet the more twist you need or more velocity. The long VLD bullets have the least bearing surface I did not run any math on the bullet I just cut the tips off at the range with my pocket knife. Just as an experiment that
improved grouping.

If you were considerate of other readers why not
use terminoligy that everybody understands.
No it is not abstract nor abstruse. What is difficult to understand cutting off the plastic tips.

Zermel,

No.1- It was humor, without animosity,
sorry it was not in synch with your sense of humor.

N0.2- I never considered it obtuse nor abstract.

No.3- While total length does impact stability,

Bearing Surface Length and Center of Mass exert greater influence.( And with respect to twist exert even greater influence).
Perhaps your observed results are due to CG change more than length.

N0.4- I consider all such reports-- anecdotal unless presented with repeatable data from varied sources.

PS-- I am honestly happy for you if your solution achieved improved results in your particular case;
for that is what most if not all handloaders seek.


Forgive me, if I retain my innate sense of skepticism;
it has, especially with respect to internet postings, served me well over time.

DuggaBoyo.
You are forgiven.

To see whether I was on the right track I did
the math on the bullet at MV 2940 .264cal which was the test
velocity.

Bullet Length of the unaltered 6.5 140gr Accubond =1.388
with a stabiliti factor of 0.97 at MV 2940 ft.
1 is margional stabilized.

Bullet Length of the altered <b>cut off tip</b> 140gr Accubond =1.269
with a stabiliti factor of 1.68 at MV 2940 ft.
A bullet is fully stabized with a factor of 1.5 or better.
Even at 3025 ft the unaltered bullet is not stabilized.

I concede the tip material has not the same SG as the lead core and would perhaps change the outcome some what? Besides the CG and Center of pressure would be different too then if it was lead core. Nor did I correct the new weight of the bullets with the tips cut off, this of coures would benefit the stability factor.

That's about it for the jack knife mutilation operation. It is not perfect but close. Those bobbed bullets shoot realy well. For a hunting bullet out to 400yrds a boat tail like on the above bullet is not needed either. It just adds to length for not much other benfits. A few extra feet of velocity
will not do much at hunting ranges.
