If anyone owns both, what kind of long distance accuracy are you guys getting with these? Just curious with which of these rifles you can have advantage over the wind...

I suppose the .260 would, but I'm not too sure because I'm not too familiar with the .260

how about distance? max effective range?

I'm not getting either, just something I have been thinking about...

I googled around but nada. most compare the .260 and 6.5x284, which is pretty much a .260 on steroids

...we are rediscovering what the Spanish figgered out a while back... </div></div>

they are... i was real close to getting my .30-06 rebarreled to a .284, but I'd have to get new dies, sell my brass, my bullets etc, so I stayed with the .30-06

I'll never forget how someone with a .260 talked down to my .30-06 about how it's like a .22 compared to his .260 that since then I have been looking for a better caliber to outdo his... lol

I'm not sure about beating a .260 ballistically, but I know a 208/210 bullet def won't be like a .22 when compared to a .260 round when it hits lol

Re: .260 vs .284

tasel,

This is a "depends" answer:

If the 284 Win is chambered in a LA, then it will smoke the 260. If the 284 is chambered in a SA, and held to a max of 2.80", then it will equal the 260 Rem when using 168 grain Berger VLD's

Run the numbers in JBM:

260 Rem 140 Berger VLD @ 2850 FPS
284 Win 180 Berger @ 2900 FPS in a Long action
284 Win 168 Berger VLD @ 2800 in a short action

Re: .260 vs .284

The .284 hits harder. Much harder.

And with 180JLK's (.735 BC) my .284 is supersonic to 1695 yards under conditions prevalent here.

The .260 is OK as a comp gun for most shots inside of 800, with 6.5x47 probably better and 6.5 Creed probably worse, but none of them have the velocity and/or BC to be a really good 1000+ round.

Re: .260 vs .284

Graham I usually agree with you, but the 260 does 1000 yards easy. I had a 1360 yard dope for my old 260. It did it on several occasions. If we are talking ELR or hunting then the .284 is the ticket.

I'm saying that the liitle bullet is running out of gas out there, and that as a competitive shooter you can tell the bullet is starting to get pushed a round a bit trying to hit 11x17 targets at that range.

In my experience, .735, .680 and .645 all work (after all, it's a G1 BC) depending on the starting velocity. FFS has the JLK's BC at .735, so I use that and it works to 1575.

Re: .260 vs .284

In his 2nd edition book Bryan has the g1 at .645. I also use FFS and find that I have to use a higher g1 than litz states to get it to work. However, if you use JBM and the litz stated bc it works perfectly. I'm not sure why you have to use a higher bc in FFS, but you do.

I haven't shot the JLK's only the Berger Hybrids and the Hybrids (especially after meplat trimming and tipping) are fantastic from my 7/300 WSM.

Bryan does talk about how close the 2 bullets are in shape adn when you look at the sketch he includes in the book they're almost twins.

Re: .260 vs .284

taseal-

The 284 is great and it's gaining steam around here but your 30-06 still has LOTS to give. A 30-06 with heavies will outrun a 260 at distance, up close you'll end up with slightly better performance but past 600yd that 260 can't hang without using the hottest performing JLK bullets available. When you put the new Hornady 225's in the 30-06 you end up with very similar trajectory numbers but a wind advantage.

I don't think you'll have anything to be disappointed with on that 30-06, it will perform.

This is exactly why I chose the 284 WIN. 180 for long range. 162/168 for LR hunting, and lots of other bullet choices for hunting/varmints down to 120gr.

Here's my take on the subject.Mike the mod will be very proud of me for not mentioning other cartridges.

6.5-284
Accelerated throat erosion at normal speeds for the cartridge.
Fewer than 10 rounds in AICS mags.Getting up there with recoil.Good in the wind.140 grainers are the norm.

284 in short action.
Average throat wear,Fewer than 10 rounds in AICS mag.More recoil but still plenty manageable.Great in the wind.For this action length 162-180 grainers are normally used but mags with more internal length and a relief cut like 300sniper uses helps with feeding and gives a tad more case volume/OAL.

260
Average throat wear.10 rounds in AICS mag.Medium recoil.Decent in the wind.

You could shoot them all to 2000 yards and hit stuff if you wanted to(might want to pick a calm day and yes they will be subsonic)but 1000Y is a piece of cake for these cartridges.

Re: .260 vs .284

I have the 260 shooting 123 Lapuas at 2970+, 6.5x55 shooting 139 Lapuas and the 284 shooting the 162AMAXs.

My "Personal" experience with the 260s (On my 4th barrel)is that it shoots better with the 123s than the 140s. I have shot mine out to 1300yds and with the 140s it was inconsistant. With the 123s a miss was due to a wind call. It reminded me of my 6.5x284.

The 6.5x55 is better with the 139/140 class bullets. You get good barrel life and great accuracy. My data for wind on the 6.5x55 for 1000yds is 5.6 MOA for a 10mph wind the 284 is 5.5 so they are really close. The 260 with the 123s is 6.2 MOA.

NOW, in the real world the 284 will shoot better in the wind because of its heavier bullet. I know, I know the computers say the ligher faster bullets will run with the heavier bullets and I guess on paper they do. However this is "NOT" what I have found actually shooting them side by side. Day in and day out the heavier bullets will do better in the wind for two bullets with the same drift data. Let the flames begin!!!!

well if your going for best ballistics then nothing because if your going to use the 30-06 case then you might as well go 280, the bottom line is on "paper" with same case design the 30 cal won't beat the 7mm with both shooting heavy for caliber bullets. Not that they are good in the real world just on paper ballistically the 7's will have a noticable advantage. you can tighten up the gap with those 30-06 loads and all but the best shooters wouldn't be able to tell the difference but that is the case alot of the time.

Can i tell the difference in wind bucking between 284 and 308 damn straight i can. can i tell the difference between 260 and 284 in real world shooting conditions? probably not, its almost always the indian and not the arrow.

rant off sorry

I know it's always the shoter, but in these scenarios, we ahve to assume same shooter shooting the same exact way. otherwise an expert marksman will outshoot a .260 at 300 yards...

Re: .260 vs .284

the .260 is not new.... it is a new name for the 6.5 x.308... shot for 20 years by across the course shooters...
I have wore out 4 barrels in 6.5x.284 (142`s@2950ft/sec.)
went to the straight .284W last year.
With the new bullets coming out in 7mm over .5 BC... the .260 runs second place to the .284 w/(180`s )... the father away from the target you get... the more the .284 has the advantage.
not opinion but fact.

Re: .260 vs .284

ugh... maybe in 2012 ill swap over to .284... i regret not going .284 now...

I dont even have my rifle back from the smith now, and wish I had gone with a .284 lol...

thing is, I dont have access to ranges beyond 1000 here, so that's why I stuck with a more traditional round, but I like cheating the wind with such a forgiving caliber
 
#27
Re: .260 vs .284

Both are great rounds, but the .284W is better ballistics wise than the .260, but not by a huge amount. The .260's niche is that it gives off very good ballistics and is a short action round. So your talking about less weight more ammo, less recoil. .284 or 7WSM for that matter with 180gr Berger VLDs ballistics wise is a pretty amazing combo though.
 
#28
Re: .260 vs .284

I used to shoot the 300WMs all the time and when the 260s came out I got the samething as a 300WM with half the recoil whats not to like.

Your 30-06 with the 208AMAX is a damn fine round for longrange shooting and I would not be afraid to compete with it against most of the calibers were talking about. The big drawback is "Recoil".

I don't want to hear any crap about "Manning up" either I went through a bunch of barrels on 300WMs so I am no rookie when it comes to recoil. I just like not getting punched around and shooter fatigue does come into play in tactical matches esp when shooting in a awkward position.

Shoot your 06 and when its shot out try the 284 or 280 or just build another rifle!!!!!

man, I would love to build another rifle, but there are other things I want... I want that bushnell range finder binocular, and I want a custom 1911 for carry...

not to mention I still have to fix my maxima's rear bumper that someone bumped into at a parking lot, and my Z06's passenger side long tube needs to be replaced

so I'm gonna have to be happy with 1 rifle lol...

yes, about manning up... with my B&C stock, and the rubber pad on it, I really don't feel much recoil from a .30-06... I can't imagine the 208 kicking that much harder than a 175. I'm used to bruised up shoulders... recoil is not a worry for me.

plus if it's hitting me that hard, I can't imagine the opfor on the other side! lol!

Re: .260 vs .284

If the recoil bothers you use that as a great excuse to buy a good suppressor
laugh.gif


My 30-06 is about 14-15lb loaded and there is only 1/8th inch of hard rubber on the butt. I don't have trouble shooting 30+ rounds in 15 minutes with it, nor does it bruise up. Yes the recoil is much higher than my 6.5 CM but that's a given.

No brake, no can on the 30-06 and it holds its own past 1000yd.

Re: .260 vs .284

I really don't feel this is a fair comparison at all

For a short action round the 260 is hard to beat. Low recoil, great bc bullets, extremely accurate, and great barrel life. All this in a short action.

The 284 is a great round. But you need to run it in a long action to shine. Also low recoil, great bc bullets, extremely accurate, and great barrel life. But in a long action

The 284 burns more powder than the 260.

If you want to compare the 260 to a 7mm you should be comparing the 260 vs 7/08

if you want to compare a 6.5mm to a 284 you should be comparing the 6.5 x 284 vs 284 Win

compare apples to apple

Both are great rounds. I would love to own both

I switched from 180 bergers at 2900 to 180 jlk's at 2900.... and the bergers were flatter at 1000 yards.. about 2 tenths flatter. jlk has an inflated BC on their 7mm 180's. the 6.5 130 and 140's BC seem to be accurate

Re: .260 vs .284

.257
You bring up a valid point. They would be more fair compaired that way but then he asked about the 260 vs the 284.

The 6.5x284 is still one of my favorite rounds but I just shoot to much to keep putting barrels on every year. That is why I went to the 6.5x55. I hope to get better barrel life out of it with performance that is between the the 260 and the 6.5x284.

Re: .260 vs .284

taseal, I'm not sure what your barrel length is on the '06, but you should be able to push those 208s up to 2800+ with no issue! I ran em out of a 308 at 2725.... Just use RL22 or better yet, Norma MRP

What length barrel do you have on your .308?

Re: .260 vs .284

Over the years I have run the 7x57 and the 260. Now that 7mm bullets have caught up to other calibers for a nice selection of LR types it is a tough choice.

On paper never helped me decide. In the field the difference was difficult to detect as the 7x57 was a bit heavier so recoil seemed the same.

I have owned a 30 ought and can say the 7mm is lower in recoil which mattered once I started shooting 50 to 100 rounds a session.

I liked my 7x57, maybe a bit more than the 260 but as far as costs went the 260 was cheaper to run and very good for all the hunting and target shooting I did.

Good Luck
