Reply With QuoteI don't know much about this round. I do know it's case was for a 284win that was necked down to 6.5. I also know that a lot of people consider it a barrel burner (1000 rounds) from what I hear.

I am getting curious about the 6.5-284 and considering building one. What original cartridge is it based upon? 308? This maybe the next rifle I build as it seems to be a killer long range round that will get me out past my 25-06 and hopefully less or similar recoil. I was thinking along the lines of 28" barrel and a slower powder (4831SC ?) to start loading. I had been kicking around a 260 Rem chambering, but the ballistics of the 6.5 sound like that they are just a little bit better for longer range shooting.

1000 rds is plenty good enough for me if it is a real shooter. I am also considering a build using the 260AI, but the 6.5 ballistics seem to be just a smig better at distance. I have never had a wildcat cartridge setup before and want to try at least one before I can not see well enough to shoot
They ARE barrel burners. There are plenty of other cartridge's that will give better all around performance.
I have one. I load H 4831SC in mine, Lapua brass, Federal gold medal match primers, and Berger VLD match 140 gr bullets. I'm pretty happy with it.
You might also look at the 6.5 x 47 Lapua, not to be confused with the old 6x47 (222 Rem mag necked up to 6mm-I have one of those too).

What would you recommend with better all around performance??? What else has the performance of this caliber with longer lasting barrel life without sacrificeng your shoulder? Sorry not trying to steal this thread.
It's not a wildcat. Savage makes the rifles and Norma & Nosler make factory ammunition for it.1000 rds is plenty good enough for me if it is a real shooter.

From what i have read, this is one of the finest long range cartridges, with outstanding accuracy compared to many similar ones. I have read that barrels may go as early as 800 rounds and some go easily to 2000 rounds, with slightly reduced accuracy towards the end. I have a fine shooting 25-06 with Shilen 26" barrel, but was looking for a flat shooting short cased round with good velocity and flat trajectory. This seems to be the cat's meow for all of these criteria. I am open to other suggestions, as I want to build a new rifle in a caliber other than the norm, but with great characteristics in terms of flat trajectory and good impact out to 1000+ yds. I want to keep recoil to a manageable level too.
The 6.5-284 seems to be the trend in the long range target game. I think you would be very happy with the performance of this caliber.
As far as I'm concerned if talking about hunting rifles the only fly on the 6.5-.284 is that (in my personal experience) it can be a picky eater! I have a Broughton barreled Savage that has had 87 rounds down the pipe all of them were fired looking for an accurate hunting load. The accuracy is certainly there, 140 grain Berger VLD's will go into tiny groups but I was looking for a load for the 125 grain Nosler Partition. It doesn't look like it will happen any time soon in this barrel but that is OK. As far as barrel life, if you are talking about a hunting rifle, how many people actually shoot in excess of 1000 rounds through the barrel anyway? When mine goes I'll just re-chamber it to .264 Winchester Magnum. This is actually my second 6.5-.284, my first one was built on a Ruger 1V stainless action, it shot great as well but had a heavier barrel so I sent it to live with my shooting buddy.

For me this will be a long range steel shooter for the most part. I would hope to do some hunting with it, but that is not my primary desire for this rifle. Its a hobby for me so if the barrel only last say 1000-1200 rounds, that is still a lot of shooting and reloading for one rifle ;D
Post some pics when you get that bad boy together.
Ah yes, my misunderstanding, sorry.Sorry, I was referring to the 260AI in regards to the wildcat cartridge :)It's not a wildcat.

Mine's just the opposite. I have a Krieger barrel and with minimal effort I have found loads with every bullet that I've tried so far. The 100 grain Nos BT's, 120 grain TSX, 140 grain Hornady SSt's and the Lapua 139 grain Scenars will shoot 5 shot sub <1/2MOA groups when I do my part.

What about a 6.5x55AI? or a 6.5-06(AI)? Either would be a little more wildcat-ish than a 6.5-284.
I just built a 6.5x55 varmint rifle and I'm kinda wishing I had AI'd it right off the bat for something a little different.
excuse my ignorance but what does AI mean?

is it just the throat that goes or does does the bore/rifling also wear prematurely?
...I'm not second-guessing you, it's just you brought up a point I had never considered before and so now I'm curious.
I suppose the whole bore wears to some extent but the vast majority of the erosion takes place in the throat, I have rechambered several barrels that were "shot out" and shot several more accurate rounds through them. I got a used Hart benchrest barrel once that was originally a 6mmPPC it had been set back and rechambered at least twice, Lord knows how many rounds were fired to require that! I cut the shank off, threaded it for a Whitworth Mauser action I had laying around and chambered it in 6mm/06. I was on a quest to see just how fast I could push an 80 grain bullet with the then new moly coating. I don't recall the exact round count (around 500) but the accuracy was great, then I rechambered it again to 6mm Mach 4, I roasted it pretty quick after that but I sure had a lot of fun with a barrel I got for twenty bucks!
I fully expect to get at least 1800 accurate rounds out of the current barrel between the 6.5-.284 and the .264WM.

Mine is a Broughton 8 twist 5c, the best it will do so far with the 125 Noslers is right around .700 for 5 shots at 100 yards. I haven't given up yet, I'm just waiting on more GM210M primers to show up!

1800 rounds That's a couple months worth of shooting. ;D Seriously, that doesn't seem too bad to me.
interesting. thanks for the info :)
Waceyf, I'm referring to my 6CM. With a 115 DTAC it has 5 inch less windrift at 1000 yards and barrel life can go 5000 rounds when loaded properly.
When talking about the 6.5-284 yoy have to realize that there are two different cartidges being loaded. One is the 6.5-284 Winchester chambering, which is designed for a short action and loaded to an overall length of about 2.800 inches. The other chambering is the 6.5-284 Norma, which uses the same case(and the same loading dies) but is designed for a long action, with an overall length of 3.310 inches. The data for the 6.5-284 Winchester chambering can be found in the Hornady 7th edition manual, and the 6.5-284 Norma data is available in the Nosler 6th edition manual. The big difference is how far out you can seat the bullets. The Winchester version, to fit in a short action, seats those long, high BC bullets well into the case, while the Norma version seats the bullets much farther out and requires the long action. While you can use data for the Winchester version in the Norma chamber, you will be getting lower velocites and pressures. Using the Norma data in the Winchester chamber can cause problems I don't even want to think about! So the only similarities in the two chamberings is that they use the same reloading dies, and the same cases, but nothing else is the same.
Savage is chambering for the Norma version, as far as I know, which makes a better long range rifle. It is just that when talking about the 6.5-284, it is important to know which version is being discussed.
Great post! I didn't know that, thanks for the info.
I don't have first hand experience... yet with the 6.5mm rounds yet. But I was reading an article that was discussing the 6.5mm cartridges. Seems that the 260 and the 6.5x47 Lapua can both easily achieve the two lower velocity nodes or sweet spots for the 140gr bullets. The 6.5x284 can get you into the third and higher velocity node. However, the ability to get into that higher node will come at the cost of the barrel. If you are willing to pay the piper the 6.5x284 is the way to go. If you want to shoot a barrel a little longer I would look at some of the slower offerings like 260 Rem or 6.5x47 Lapua.
Just my .02
