I'm not sure if this forum allows posting direct links, so suffice it to say that you can go to powder company websites, such as Hodgdon's, and they have a page where you can input a cartridge and get loading data.

I just looked up the 6.5-284, and they list several.

A 140 gr psp can be pushed to about 2900 fps with the right powder. My 270 WIN pushes a 130 at almost 3100 according to my cheap chrony. I'm not sure I'd go that route. I'd rather go with the 270 WSM.

Check other data, though, before making a decision. I've really not researched it beyond this site. I didn;pt even check downrange velocities. The good BC of the 140 gr .264 could prove more benificial beyond 300 yrds.

All my hunitng is in pretty thick Tennessee or Michigan woods; my farthest kill with a 260 is less than 100 yards, and I';ve only shot two with my 270 beyond 200 yards.

Posting informational links is OK on the board. When posting links strictly for commercial purposes that its a no-no.

Where the 6.5 is going to shine is down range, 300 yards and on. Use one of the on line ballistics calculators and do some bullet swapping between a 6.5 and 270. Just pick a couple of bullets like the Nosler Ballistic tips. Just use the same velocities, they will probably be pretty close anyway.

Nosler has some load data for the 6.5-284 Norma, not sure if that's the one your looking for. But they have load data for 100, 120, 125, 130,and 140gr bullets. On the home page go to where it says resources and then you'll see it.

As JAKEWAY said the hodgdon websitehas load data. Accuratereloading.com also has data. And the Hornady website has a ballistic calculator that is pretty good for comparing cartridges. You can compare estimated trajectories, wind drift, and also, retained energy.
Hope this helps, Ron.

Considering the 6.5x284 is cleaning up on the 1000yd matches [where ballistics are very critical], I can think of no better gun for deer-caribou out to as far as you should be shooting. With the right bullets I wouldn't shy away from elk when carrying the 6.5x284 either.

i agree with bandit, also don't get too wrapped up in muzzle velocity as it is only a small piece of the pie. the ballistic characteristics of the bullet is much more critical for long range shooting than a couple hundred fps... if you were to look at a long range chart i'm sure that the 6.5 bullet you mentioned would surpass the 270 w/ 130gr quite easily in all regards, ie wind drift, trajectory & velocity.

I shot the 6.5x284 for acouple years mine had a .290 neck and 28" barrel averaged 2950fps with 140/142gr VLD bullets and thats a pretty standard load for 1000yd. I parted that rifle out last year had acouple other projects wanted to play with.

You mentioned your gunsmith reccomend a Broughton 5c barrel you like that barrel. I did a 300WSM with a Broughton 5c 1/12 twist barrel been a good fast barrel besides being very accurate.

You may find this intersting I've got a 270 with a Lilja barrel and 270WSM with a Lawton barrel. Acouple year ago drew buck antelope tag on a friends ranch out east decided to take the 270WSM. Make a long story short didn't see and shootable antelope but he has a few PD out there so decide need to shoot afew. I got afew 300/400yds didn't have enough glass for any longer shots.

The lack of good VLD match bullets is a problem for the 270 and thats one reason no one would even consider the 270 cal as a match type rifle much less as a LR varmit rifle. After that trip out east got talking to my gunsmith and Berger been making some hunting VLD bullets for the 270 and that 150gr has a BC .531 with Wildcat bullets being sold wasn't much chance of getting any of their bullets. I decided on having a 270Wby build and see if it work as a LR antelope/PD rifle and case be headspace on the shoulders and no Wby freebore used one of Rock's 5r barrels. I should have that rifle pretty soon be a fun project to play with and I should get a antelope tag on my friends ranch this year.

Gunsmith got a Kreiger 6.5 cal 1/8 twist barrel for me going to do another 6.5x284.

Well Keep us all posted on your projectn there fun that all I can say.

I believe Berger makes their VLD hunting bullet in 270 in 130 -150 gr, another excellent cartridge for long range hunting mention on the 6br site is the 7mm SAUM

Hi Logger
You should have had a look at a 260rem. There's not much difference ballisticly between the 6.5x284 and the 260rem but the 260 is a lot better on barrels, Lapua now makes 260 brass and it has the 308 as a parent cartridge so it shares the same dimensions, so it will take the same bolt face, you can make brass from the 308, 7mm08, 243 ect. The 260 is pretty common in long range target comps (F-Class ect) but it also makes a great hunting caliber.
Here is a good article

I really dont see why they made a 6.5x284. What makes it any better than the old 284 win. that has been arround for ever? There is alot better bullet selection for the 7mm than for the 6.5. In my ooinion with a long action, and a long throat, in a bolt gun , the 284 would be a better round. you could use the longer, heavier bullets, that could be seated out farther , thus taken full advantage of the case capacity. The longer heavier bullets of the 7mm would have a higher B.C. and perform better at longer distances, and be less effected by wind.

One advantage for the 6.5x284 Norma OAL is 3.310" for the VLD type bullets and that case is a proven winner @ 1000Yds.

There is appr 10 or more years jump that the 6.5x284 has enjoyed as a match rd over the 7mm's. I think the 7mm bullets are still playing catch up if you look at some of the new 7mm bullets from Sierra/Berger.

With the SAAMI spec on the 6.5x284 Norma and the loading data I think for most that would be a better choice vs playing with the 284 that you mentioned.

Be nice if there was a SAAMI spec for OAL with the longer bullets in the 284 case and loading data for it. My 284 OAL is 3.100" and it's on a long action.

There is a trade-off for every advantage gained and the 6.5's have come into favor as match rifles because they offer excellent ballistic performance without creating uncomfortable recoil. Also, there is no denying that sometimes a cartridge just catches on when others that are just as good wither on the vine. There's not always a great explanation for why but I think the basic case geometry of the 6mm PPC can be looked at as a derivative for both flavors of the 6.5x284. The ol' 284 Winchester was thought to be just the right size to neck down to 26 caliber while maintaining the short-fat ratio of the 6PPC.

The reason for the 6.5x284 popularity can be traced the the unsurpassed BC & SD values of the 6.5mm bullets. For over 100yrs the 6.5x55 has been killing critters way beyond paper ballistics, and winning long range matches. Those same ballistic atributes are being seen with the 260 Rem, 6.5x47, 6.5creedmore, 6.5-06, and 6.5x57. If you want to hit targets at LONG ranges with minimal recoil and maximum results, the various 6.5mm cartridges are the ones to beat.

Dog gone it! Now I gotta get one of these. I've already got all the guns I need, but the list of guns I WANT is getting larger each week.
