6.5mm as an antelope killer

I doubt the 6.5 cartridges are the best all round big
game cartridges. But in the deer and antelope area,
they are close.

Knowing Wing is building a 6.5 x55 Scandinavian, I
thought of bullet choice for antelope in 6.5 might be
interesting info for him.

I've used the 129 gr spire point interlock, the 129 gr
V-max and NOW using the Hornady 123 gr V-Max. why?
Best ballistic Coefficient .510 better than some ELD
bullets, and my antelope experiences seem to be longer
range every time I see a critter. The V-max always
expand...flop.

I don't know if I would use a prairie dog bullet on an antelope.
But the boys swede 6.5 has killed two bear a moose and a but load of deer and antelope . I have no idea what he uses in it as a load.
He got a Kimber 6.5 Creedmoor, still working a load he has found out it DOES NOT LIKE 145 gr anything.

If I was to go with 6.5, I'd have to try nosler's 142gr ABLR with .719 BC, but I'd push it @3,200fps in 26 Nosler.

I've used and have 257wby, 270wsm and 300wm for antelope, they all run pretty decent at extended range, wind can be a factor in lighter ones. I had a 270wby before and it would be pretty good with 150gr ABLR (.672bc) @ 3,200fps, as would 28 nosler 175gr ABLR (.672bc) @ 3,200fps.

I won't have the gun back for a month or more, but I
have started gathering stuff. I bought a set of dies and
a box of 140gr Nosler Accubonds. Like Robert I wanted
Accubond LR's but the store only had one box of
accubonds and a whole shelf full of LR's. So I got the
ones that might be harder to get later. I will be trying
both.

I also plan on trying Sierra 140gr Game Kings. I have
had really good luck with Game Kings and Pro Hunters in
the past.

I am leaning towards 140 grain bullets first and if they
don't shoot good then I will try 129's.

I have always tried to find the most accurate load I can
then worry about speed (drop) from there.

I have killed many an elk with 130gr .270 bullets. Am I
safe to assume a 140gr 6.5 should work just as good?

As some of you know, my "dream" is to someday have/build a .264/06. I was thinking in terms of the heavier bullets, but with the awesome penetration of the 6.5, heavier may not be necessary.

Looking forward to following this conversation - thanks, Bear, for starting it!

Those Nosler's sure look good on paper. I would imagine the recoil would be a bit stiff though. Not to mention the price tag on the brass.

Tash made a good point about the penetration ability of
the 6.5. I have read that they are great for penetration.
Any idea why they would be better than anything else?

.......Was it Hemmingway that shot the charging rhino end to end with a 505 Gibbs?

Bullet design is all. Find the optimal expansion on a long and lean bullet, it will bury deep as it expands evenly.

6.5mm do not work well on antelope out of a 6.5x55

.264" bullets are 6.71mm. If you shoot a 6.5mm in a 6.71 bore it will
rattle down the barrel and have terrible flame cutting and accuracy.
Give up your dreams of a accurate custom 6.5 and join the 6.71 team.

The guys can correct me if I am wrong, but I believe that it is the sectional density of the bullets, which tend to be long for their weight.

BEAR: I use the wonderful and wonderfully accurate Nosler
100 grain Ballistic Tips in my 260 Remington.
I have shot Mule Deer, Whitetailed Deer, Antelope and
Coyotes with it.
I have yet to need to shoot an animal twice with this
set-up.
My Rifle is a Remington 700 VLS (Varmint Laminated Stock)
with the 26" heavy barrel I have a Leupold 6.5x20
variable scope on it and its always equipped with a
Harris Swivel Style Tall Bi-Pod.
I am now of the age and mindset (and have been for the
last 20 years) to be able to intentionally wait for Deer
and Antelope to give me a broadside heart/lung shot, and
again I have NOT had to use a second shot on game to date
with this rig.
This 100 grain Nosler Ballistic Tip has sure served me
well.
Good luck with your 6.5.
Hold into the wind

Recoil wouldn't any worse than RUM, just bit less case capacity used, to get there. In order to get above 3,200fps, with a bullet heavy enough for game, you'll have some recoil and cost.

Much of the great penetration is from the old 175gr bullets, which has high SD. 140gr .264 bullet has similar SD to 175gr .284 bullet.

Sectional density (SD) is the numerical result of a calculation that compares a bullet's weight to its diameter. To calculate a bullet's sectional density divide the bullet's weight (in pounds) by its diameter (in inches), squared.
Consider old bullet, where reputation came from.
175gr .264" bullet (175/7000)/(.264*.264)= .359 SD compared to
140gr .264" bullet (140/7000)/(.264*.264)= .287 SD
175gr .284" bullet (175/7000)/(.284*.284)= .310 SD

It would take 200gr .284" bullet (200/7000)/(.284*.284)= .354 SD, or a 235gr .308" bullet (235/7000)/(.308*.308)= .354 SD, to have similar SD and penetration.

Thanks Robert. That's very good information. Would it be
safe to assume that a 140 grain .264 bullet traveling at a
muzzle velocity around 2700 fps. would be a satisfactory
choice for elk at 250 to 300 yards or less?

Thanks Buddy.

I have allready been beating myself up over caliber for
a year or more.

Would have better performance, than 130gr 270win and many consider that enough for elk. I would like a sturdier bullet, than BT/SST though AB and interlock should preform well. It would have about the same SD and velocity of 160gr in 270, with a .007" smaller diameter, so it wouldn't give up much power.

One reason that the 6.5 cartridge gives such good
performance is that it has light recoil, which promotes
better shooting.

The 6.5 Creedmore and the 260 Rem have the added
advantage of fitting perfectly into a small action.

Having shot and reloaded for the 264 Win mag (AKA 6.5-
300); I must say I could not see anything different than
the 270, except for the belt!

I have an old 6.5 mauser that has been sporterized. It is not the most accurate gun but it is adequate. I picked it up at a pawn shot years ago just for a truck gun. Since that time I have started a number of new hunters on that gun and it has always been an excellent killer. The only bullet I have used is a 140 gran hornady and have never had a problem with it. It just works, nothing fancy or flashy or complex. It really hard to argue with that.

Thanks Robert.

I am one of those guys that shoots elk with a 130 grain
.270. I never had to track one very far. I never have had
one fold up either. Usually they kinda hump up then stand
there for a few seconds then fall over.

I am hoping it shoots either 140gr Acubonds or 142gr
Acubond long range. Those are the two I have to try.
