6.8 spc any good for hunting?

True enough about the plinkin' loads, but trajectory-wise there is no comparison as the 6.8 shoots much flatter. 7.62x39 is down about 93 inches at 500 yards compared to around 56 inches for some of the better 6.8 hunting rounds.

gimmie a break, who shoots a 6.8 at 500yds, But I'll play anyhow

notice I said 7.62x39mm HANDLOADS

my 2400fps 125g nosler ballistic tip load matches remingtons 115 ultra bonded load even out to 500yds

at 500yds from a 200yd ZERO my 7.62x39 load drops 69.5" with 588fpe

at that same set of parameters 6.8 drops get this 68" with only 481fpe

a whopping inch and a half at 500yds, and this is BEFORE you drop 200fps off of remingtons overly inflated velocity numbers that I allude to in a previous post. Even with these numbers MY 7.62x39 load packs MORE energy at that range

So by "much flatter" to you must mean 2% :eek:
 
"gimmie a break, who shoots a 6.8 at 500yds, But I'll play anyhow"

Not sure how they do things in your neck of the woods, but most folks put their ballistics tables out to 500 yards for a full comparison.
I was comparing Federals soft point hunting round with SSA's
200 yard zero
6.8 SPC
300yrd 10.4
400yrd 30.6

7.62x39
300yrd 14.5
400yrd 43.9

Was attempting to compare apples to apples by comparing commercially available loads that have verifiable and published data. That is something I don't have with your handload data.

Remington loads are also the worst case scenario for 6.8 SPC. Much better and more accurate loads are available from Hornady, Seller Bellot and SSA. Currently the hunting round most folks seem to be using is the SSA 110 hunting round.

If you would like to see a good catalog of things being hunted and the results, head over to 68forums.com. Lots of folks getting good results with this round.

I still stand by my original statement. That properly handloaded 7.62x39 will match 6.8spc. For us handloaders there's a great deal of improvement to be made over factory 7.62x39mm offerings. On the other hand with 6.8's throughly modern bullet selection and pressure rating the best a handloader can hope for is to match factory 6.8 loadings. Thus even comparing your chosen SAA load

200 yard zero
6.8 SPC
300yrd 10.4
400yrd 43.9

vs

200yd zero
7.62x39mm 125grn nosler @ 2420fps

300yrd 11.46
400yrd 34.08

something doesn't add up with SAA's trajectory table, the 400yd figure doesn't seem to add up with what it should be. Either way at hunting range inside 300yds the difference is only an inch . Hardly enough to beat your chest over, none of which however takes away from both rounds ability to cleanly take game at serious ranges.

krochus,

Haven't been keeping up with the latest developments in 6.8 SPC lately huh??:confused::confused:

Over on 68forums.com (http://www.68forums.com/), the people developing hand/hunting loads are getting very respectable performance out of the 110-115g hunting loads. Try average of 2800fpm out of 16-18" barrels!!!:what:

I understand why someone would want to have an AR in 7.62x39 with all that cheap import junk to shoot, but you can't reload steel cases. If you are going to down play the 6.8, at least get the most current information. You keep comparing your hand loaded 7.62 with factory 6.8...not too fair I say. If the OP wants to look into what the 6.8 can do, just join in the forum above. You have to register (that keeps out the spammer/porn people), but it is a great group of guys and they have really done some tremendous things with this round including taking a bull elk at 372yds using 110gr Accubond at 2880fps, same 20" 13 twist 3 groove built rifle!!!!!!;) Not everyone can do that, but it was a clean kill with a very good shooter.

Again, check out the latest information and you will see that the 6.8 is a great hunting round for medium game out to 400yds with the right loads.
 
What pressures are they running with that 2800fps loading? Is it safe? How many loadings do they get out of those cases? Oh wait they have the magic 1:12" twist rate that multiplies velocity.
 
jerkface11,

I gave you a link that will give you all the information you ask. Did you read it or are you just wanting to spread mal content?? The tests were done using barrel pressure testing equipment, so the information is there for all the barrels/loads!!!!!!!!!!

Yes, the twist rate does have an effect as does the chamber dimensions. Is there something secret that is being hidden from people??? I think not!!!!!!:fire: All you or anyone for that matter has to do is do their due diligence, but for some, perhaps you and krochus, reading is not your forte!!!

Oh well, sorry...the information is there for everyone!!!!!:neener:
 
You're right a special rate of twist will allow 6.8 spc to get the same velocities as .270 winchester a cartridge with DOUBLE the case capacity. I think I'll build a .270 Weatherby with that twist the bullets will probably flash into plasma.
 
Folks on 68forums.com are actually working up these loads and publishing their data.

Feel free to publish yours when you get your Weatherby Flash/Plasma round going.

Twist rates, headspace, chamber dimensions, these can all drastically affect muzzle velocity as much as barrel length, case volume and powder efficiency. There is a point of diminishing returns on case size where the round loses efficiency. It is not a linear thing. Twice the case capacity will not get you twice the velocity.... but you probably already knew that. The tone of your posts seems to be more to degrade others than to actually discuss the topic.

There is no twist rate in the world that will make 6.8spc shoot faster than .270 winchester. The only way to do that is to dramatically increase the pressures. I do notice that you 6.8 fans seem to be very defensive of your pet cartridge. Since any time someone questions your nonsensical ballistics they get accused of being rude or degrading.

As for the people on 6.8.com or whatever they can work up any overloads they want to. I just hope they let the people next to them at the range know before they start shooting the things.
 
"There is no twist rate in the world that will make 6.8spc shoot faster than .270 winchester. "

I never said that there was.

"As for the people on 6.8.com or whatever they can work up any overloads they want to"

Some of the hotter loads I have seen data for were done in a pressure barrel so that chamber pressure was being measured along with the velocity. I haven't seen any irresponsible behavior from those reloading on 68forums.com.

"I do notice that you 6.8 fans seem to be very defensive of your pet cartridge. Since any time someone questions your nonsensical ballistics they get accused of being rude or degrading."

My comment about your attitude had/has nothing to do with your opinion of this cartridge.

I would have thought this tread would have ended with a "yes, at a reasonable range".:confused:
 
so you exact-o thread dissectors are saying that a 6.8 will not kill a deer as dead as any other centerfire?
Click to expand...

With the right bullet placement and at close enough range, a 22lr will kill an elephant as dead as a 416 rigby. your point?
So if I'm hunting grandpa's beanfield and expect shots @400 yards or so, I'd go with a 270 or 7mag etc...but a 6.8 spc would work, it's just that you'd be handicapping yourself.
 
come on guys

Can't we get along.
I thought this place about learning from each thru our experiences
with a certain guns ammo accessories.
Not to down grade someone just because you think you know it all.
I have read a bunch of stuff over at the 68forums.com
The information seems pretty straight forward.
There will never be a magic do all ammo caliber or rifle to do everything.
Each hunting situation is different.
And anyone that believe's they know everything about everything is just stupid.
Back up opions by facts proveable stuff not guessing but through personal hands on
Experience and not hearsay or a friend told me or that crap
Fine if someone thinks the 7.62 is better than a 6.8mmspc fine prove it
Don't start acting like a baby. Show me examples for or against.
I'm lookin to by a new upper reciever for my AR15 convince me.
