Long action chamber in short caliber , good and bad ??!!

Even with reloading, I see pretty much no reason to go with a .260 in this day and age.

The extra few fps doesn't outweigh the cons. And if I really was concerned about having more horsepower then a 6.5 Creedmoor, I would be looking at cartridges different then the .260.

Only negatives I can see is if you want to use an external mag. Other than that, the 260 has more advantages. - dan

.260 Pro's:

- Goes slightly faster

6.5 Creedmoor Pro's:

- OAL optimized to feed from standard magazines and SA footrpint actions
- Plethora of quality reloading components
- Plethora of quality factory match ammunition
- More prefit options for rebarrels
- More factory support/options from rifle manufacturers
 
As far as .260 goes...
No issue getting outstanding performance with rounds loaded to function from AICS pattern magazines.
I don't shoot factory match ammunition, so availability thereof is irrelevant.
Plethora of quality reloading components for .260.
Couldn't care less about prefits - I do my own machining.
Couldn't care less about factory support/options. I don't buy factory rifles.
At 1000m I doubt the target can tell the difference.
Shooter is best served by getting out on the range and shooting in whatever conditions exist, rather than playing equipment games.

6.5 bullets are 6.5 bullets. 6.5 barrels are 6.5 barrels. 260 brass is one pass through a press with 308 brass away. So really, the only "advantages" the 6.5 CM has is more factory ammo for the non-reloaders, fits in a AR10 mag (yay prohibs) and it's trendy. Yup, huge advantage alright. - dan

I guess you don't understand what a "prefit" is. Big deal to some, for others the availability of prefits is not so much of a big deal. But that's a pro the 6.5 Creedmoor has.

I really don't care to argue this any further, I don't see the point. Glad you like the .260. There's no real reason to get a .260 over a 6.5 Creedmoor these days, and if you want more punch in a 6.5mm, there's much better options today then the .260.

To each their own.

Not to most people. I don't even disagree with you on most of it, there's barely a hairs difference. But listening to people juice themselves over a CM just because it's the flavor of the month has become more than averagely annoying. It's no different, as I stated earlier, than Billy Newhunter who bought that 300 Win Mag cause it's the killingest gun ever. Not one guy in a hundred will know the reasoning behind it, or the differences between the two rounds. Whatever, enjoy what you got. - dan
 
Theres less trimming with the Creedmoor, I’d say thats a significant advantage.

Truth is the Creedmoor exploded in popularity because it was well supported by Hornady. People can whine and moan all they want but Hornady deserves a win for the Creedmoor cartridge. They put the time and money into it and it succeeded.

I hope Hornady supports a good 7mm cartridge next.

7mm - now you got my attention. Define "good."
 
7mm - yes, there must be a huge gap to be filled somewhere between a 7-30 Waters and a 7mm Ultra Mag?? Something else must be "needed" by someone?? Not as if a marketer/sales department can ever create a never before known to be "needed"??

Yes there is a gap to be filled. The 7wsm, 284win, 7saum, and 280rem are all the closest examples but they are all oddball chamberings. Something thats improved over those 4 choices and actually commercially supported.
Currently the 2 most common 7mm chamberings are 7/08 and 7 Rem Mag. They both leave things to be desired. 7/08 is excellent but it really lacks the case capacity for the high BC bullet choices.
 
Do not take an old fart like me too seriously. I think 7x57 is about primo for the 7mm bullets, and I send 6.5 mm bullets with a likely older 6.5x55. I shoot deers mostly. I do not often shoot at paper targets; I seldom shoot at gongs, except to help me work up a hunting load, refine my sight settings and to practice firing that load. So shooting at game is what my shooting is mostly about. I understand there is a large community that views their shooting purpose to be different. All good! Burning powder and trigger time is almost always helpful!!!

Let's say 6.5 creedmoor in Rem700 LA!

There gets to be a point where a chamber/barrel can only efficiently burn a finite amount of powder.

This is easily seen, with the introduction of new powder coatings that move the pressure curve further out into the barrel, usually increasing velocity and dampening harmonics, without increasing ignition pressures beyond safe limits.

The 6.5 Creedmore is a cartridge designed around these new powders.

IMHO, it will do anything the 260 Remington will do with bullets up to 140 grains, if the magazine will allow the bullets to be seated out far enough to increase the powder, depending on which one, by appx 5+%

You can't do that in a short action rifle.

I built a 6.5 Creedmore on a Winchester Mod 70 FWT, push feed, with a 1-8 twist standard weight barrel, 23 inches long for my sister to hunt Deer with.

This rifle started life as a 30-06 and didn't have a magazine spacer. I left it as is.

I built a 260 Remington with a similar barrel, other than it's appx a half inch longer, on a Remington 700LA.

They are both better shooters than the people shooting them.

Velocities are within 50 fps of each other, but that may just be the nature of the barrels.

No matter what loads I try, the results are the same.

Normally, the 6.5 CM will show appx 100-150fps LESS velocity than most 260 Rems.

By being able to load the bullets further out, the 6.5CM basicly duplicates the 260

The Win Mod 70 push feed has no problem with feeding any bullet weights or length.


Some people like to point out that there is a longer bolt throw. We're not in combat and even under hunting conditions, 1/10 second isn't going to mean anything.

The extra 4-5 ounces of weight isn't going to bother anyone and that weight actually helps to balance the rifle between the hands.

As for length. That's up to the individual shooters requirements, including velocity and bullet weights.

Note that most of the named cartridges started life as different loads, nearly all as .30 calibre. I agree, there is room for innovation in the 7mm line, now that our neighbours to the south have finally warmed to cartridges with metric designations. I have had good success shooting a 7mm for ELR. There are competition shooters who run sevens, but they are few and far between at the moment.
