It's all Timing. Release the right product at the right time and it will supercede your expectations.
Good example 270 Win & 280 Rem. The 270 was first and was a total hit and remains the same to this date. The 280 Rem,equal if not superior, was a late bloomer, by thirty years or so and really never caught on as far as sales went.
All in the TIMING in my opinion

while it is true that the 260 never gained the popularity it deserves, it is still one of the best Whitetail cartridges. Therefore, buy one now and stock up on reloading supplies!

I certainly would not be advocating for anyone to purchase a firearm chambered for a difficult to find/could soon be obsolete cartridge and spending hundreds more on "supplies" and that is only ifyou are well into reloading now, Otherwise change the $$100's$ into $ 1000.s$. I guess then when later in life you decide you sell your so well admired 260 Rem, you'll be able to unload a couple of grand of reloading gear too.

Well I like the 7mm-08 and 260........no I do not own either at present. If I was going to get something like that I would be more inclined to go for the 6.5x.284.

I agree with the 260 being an excellent round.
It may hang by a thread, for a while, but I think it will stick around. It's fills a big hole for rounds from the 308 case.
It also took a lot of years for the 7-08 to gain any ground. It now has quite a following and may be one of the better rounds ever developed.

Black Hills just made 50,000 .260 rounds using the 139 Scenar, at the request of GA Precision, for, you guessed it, long-range shooting.

Nosler and Winchester are reported to be bringing out .260 Rem brass in 2007.

Many long-range shooters are building rifles in this caliber.

That's good news. It's a fine round and would also fit into the all around catagory for hunting in the lower 48. It could quite possibly become more popular than the 7-08. Especially with the small framed hunters.

the 260 rem is an excellent round, but i think hammer is wrong. the proliferation of 6mm and 25 cal bulleted offerings and the utter popularity of the 270win and wsm has doomed the 260 rem.
and as far as hammers comment abot the timing of the 270 vs. 280. i believe that rifle offerings rather than timing is what makes the inferior 270 the more popular choice. the 270 was offered in the ultra popular win m70 upon its debut whereas the 280 was introduced in a pump gun! even till this day one must make a concerted effort to even find a 280 as opposed to tripping over the 270 every time one walks into his favorite gun shop. i call a pox on remington for creating the fantastic 280 then dooming it by offering it in a pump gun.

lets also say that to some people Jack O'Conner was considered god and he spoke highly of the 270win, when in reallity he used that darn 30-06 more then anyother round for his hunting, but i agree with jakk280rem the 280 is by far the better caliber and has a much broader bullet selection, and yes i damn rem for putting it in a semi, dumb move on there part. side by side neck and neck the 280 with out do the 270 everytime. and if you hand load then the 280 will really shine i personaly like my 280AI.

This is a bit off topic.
Hello, is there anyone home.
The thread is titled Rem 260 and I'm reading about comparisons on the 270 and the 280. They aren't even on the same case as the 260. I don't care to hear about how the 280 outshines the 270, in this thread
I'd rather read about what is known about the 260 in this thread. All this tells me is you don't have any knowledge of the 260 rem.
I'm sure there's a thread that discusses the attributes of the 280 to the 270. If not, start one.
The .264 diameter bullet is a choice round in many circles of shooters. Especially with the target and long range crowd. If it didn't have exception capabilities. They wouldn't make it a choice diameter.
The 260 rem, 6.5/55, 6.5/284, 6.5-06 and 264 wm are all exceptional shooters and more capable than their size may suggest.
Personally. I would take a .264 diameter over a .284 and if I needed something larger than .264. I would choose a .308 diameter over the .284.
