It is based on the same parent case, right?
The .280 has the shoulder moved forward a bit more and still maintains a better neck because it is approx. .046" longer than an '06. The Sherman moves the shoulder forward even further and blows the taper out of the case to .460" at the shoulder. I use .270, 280, .280A.I. or the best are 6.5x65RWS cases.......Rich

Re: 260 Rem Vs. 6.5-06

There's been some things said about barrel life for some 6.5mm rounds that appear to me to be way off the mark.

Years ago, a friend I used to shoot 1000 yard matches with had a 6.5-06 with a Hart barrel in a custom made solid bottom Weatherby action (made by Roy Weatherby's shop just for him). It lasted about 800 rounds of excellent accuracy before going really bad in less than 20 shots. I was shooting a .264 Win. Mag. at the same time that lasted 640 rounds before going bad in less than 5 shots.

A decade or two ago when the 6.5-.284 was first used in long range matches by a friend of mine as well as his wife and her two daughters, they won lots of matches and set a record or two amongs them. They've worn out a few barrels with this cartridge. They get about 1500 to 2000 rounds of good accuracy before the barrels start going bad. That's better than 1000 to 1200 rounds with the 30 caliber magnums they used to use. And a lot better than the 800 rounds or thereabouts the 7mm Rem. Mag. was getting. They've also been using the 6.5-.308 across the course for 200 to 600 yard matches winning a lot.

Note that these barrel life numbers are based on those that shoot 1/4 MOA or better at 100 yards, 1/2 MOA at 600 and 3/4 MOA at 1000 yards. Barrels that start out with worse accuracy will seem to have a longer life. US service rifles starting out in the 1 to 2 MOA accuracy at 100 yards will have a barrel life of near 10,000 rounds. Remember that the more powder burned for a give bore size, the shorter barrel life will be.

Someone mentioned that a cartridge whose shoulder angle was such that it caused the powder burning to erode the throat faster and stated the .308 Win. caused more throat erosion than the .30-06 because of this. Well, that contradicts the reality that happened in the mid 1960's when the .308 Win. replaced the .30-06 as "the" round to use for conventional high power rifle matches shot through 600 yards. The .308 was getting about 3000 rounds of good accuracy compared to the 2500 or so produced by the .30-06. At least this is what the best shooters (NRA master classified) reported and they're better qualified to judge accuracy life than those with lower classifications. And it's been my experience too.

Re: 260 Rem Vs. 6.5-06

How and why did the 280 get interjected here when the thread was the .260 Rem VS the 6.5/06 cartridge??

Re: 260 Rem Vs. 6.5-06

260 Remington: I’ll write how I got there, agree or disagree…
Forty years ago Jack O’Connor wrote about all the big game in Africa and North America he either shot himself or witnessed shot with the 7x57 Mauser. Jack wrote the 154 grain bullet was the best all around bullet in the 7mm Mauser and you should recall that bullets of over 40 years ago are far inferior to the superior bullets we have today. In fact, Petzal and Barsness are both gun writers of today advocating standard cartridges over super magnums because of, in part, modern super bullet construction.

Today, the modern 7-08 is the equivalent of the 7x57 and the 260 Remington is the 6.5mm cartridge also necked down from the .308 Winchester. As we know on this forum, the 6.5mm bullets have ballistic advantages over 7mm bullets though both are excellent choices. I decided to have a 260 Remington built with a 24” eight twist barrel in front of a custom action.

I shoot 140 grain bullets; either a 140 grain Berger VLD for deer sized game or an old school, deadly 140 grain Nosler Partition for elk and moose. The 140 grain 6.5mm Nosler Partition has higher sectional density and ballistic coefficients than the 160 grain 7mm and 180 grain .308 bullet which gave me confidence in the elk and moose woods. Let’s recall how a bullet (or arrow) kills: tissue destruction AND penetration; and a 140 grain penetration bullet like the Nosler Partition in 6.5mm does the job.

Both the elk and moose I shot were one shot kills. The elk was a DRT (dead right there) high shoulder shot and the moose ran 60 yards, laid down and died after being double lunged with the partition. Jack O’Connor was right, the light recoil permits precision shooting and the excellent ballistics of the 6.5mm 140 grain bullet does a great job penetrating and killing game.

After listening to a Saskatchewan Outfitter complain about my rifle’s caliber, I took up the 140 grain Nosler Partitions in the 260 to keep him happy and dropped a heavy, mature whitetail buck right on the feed pile, DRT. The 300 magnum crowd enjoyed poking fun at my “woman’s gun”, but I reminded them that my whitetail was the only DRT that week and one of the cavemen got “scoped” which bled all day.

Had the 6.5-06 not been a wildcat, I might have considered it but I have zero complaints about the 260. Quality brass is available, my loads go into Nosler brass.

As has been discussed by others on this forum, I consider this rifle to be an easy consistent 500 yard terminator of non-dangerous game when I have time and know the exact range and it is fun to ring the 600 yard 10” gong nearly every time when I do my part correctly.
