Ha, "NEED" is one of those blasphemous words we never speak of around my house. Hell, if "need" were a prerequisite to purchasing or building another I'd have a safe with a whole lot of empty space in it and there's just nothing fun in that....

I have a .260 reamer with a 30* shoulder. Haven't tried it yet. but, think it would be a faster 6.5 need moor.
I think it would run 140's in the upper 2800's with no pressure problems.

Send in your 6.5CM to Hammer and have them ream it out to 6.5 Beanmore. In essence, it's a 260AI with slightly less shoulder angle.
Skip ahead to page 23 of the above thread....3945fps average for a 80gr HHT...

Not familiar with that one but if true, that sounds sweet as can be! I think just maintaining the body taper..or very close to it and a 30° shoulder on a 260 wildcat would be a super hunting cartridge and maybe do quite well in competition as well. I realize it gives up a tad bit of capacity by keeping most of the body taper but from a repeater, it sure makes them feed better than a true Ackley...IME. Same with the 30 vs 40° shoulder. Not much to be gained there vs the smoothness. Someone mentioned having to trim more with the standard body taper. I can't disagree but I do believe a proper sizing die for the chamber makes that "almost" a non-issue. I don't do it but lots of people believe in trimming any case after every firing. Again, not for me but every 5 or 6 firings wouldn't be deal killer at all, to me. ..and I bet it will go longer than that between trimming with the right sizing die. At least that's my experience. I suppose it'd be very close to a cm when done, but kust a tad bit more capacity and a tad less than an Ackley
It's pretty hard to like one and not the other. Mag length is the only significant difference in my opinion and that only matters on some guns. Both are very good but one has been promoted almost like it was an ARC or something,while the other, like a dinosaur. They're really so close that the performance difference is negligible. Each are going to have their fans and neither is wrong.
One was brought out by Remington in 1998 and thrown behind the 8 ball with slow twist barrels from Remington and no decent match ammo and one was brought out in 2007 and had rifles with good twists available, good factory match and hunting ammo available and also supported by quite a few companies. It could have been the timing with the .260 coming out before the "tactical" matches took off and the 6.5 Creed coming out in the midst of it and made as a match cartridge.
And the bold sentence is important as some here are equating velocity to performance and it's not but the difference is negligible.
Oof. I got lucky and picked up two boxes at $93 apiece.
The 260 hard heads are gonna stick with what they have in most cases. I'm one of them. Tough to just get rid of all the reloading components of the 260 and purchase all new 6.5 CM stuff. If I were starting over today, I'd opt for the CM. The little performance difference means nothing to me. I run a long action with my 260 due to OAL with 140 class bullets to get the best out of the case capacity. With the CM, I could run a SA and get 90%+ of the case capacity using 140s. Probably 100% with certain AICS mags. There's a reason why people are opting for the CM and it's not just because loaded ammunition is available.
^^^^^^^
This right here.
When you limit the COAL of both rounds to fit in a magazine there is little difference.
How many are running a 260 in a short action out of a magazine with a SAAMI chamber with long bullets?
Not a bot or stirring the pot. Trying to get as much information as I can. Responded to the initial post on the hide and did not have anything else to add.
Near as I can summerize is a little more velocity out of the 260, but staying in mag length may be difficult (especially if going beyond 147 gr. bullets).

Just like the 284
I have a 6.5 Creedmoor. If I had a 260 I wouldn't have bought the CM barrel. If I wanted more than the CM I would have opted for one of the hotrod variations. I did notch out the ramp for longer bullet seating and I'm using MDT binderless magazines allowing longer bullet seat for things like the Berger 153.5 LRHT's. I'm not familiar with the Seekins. If they take AICS magazine you should be able to get longer bullet seat and a bit more flexibility for longer bullets if the barrel throat will allow.
It was developed, must be twenty years ago now, by Robert Whitley, who called it the 6.5 SLR, also did a 6mm version, had Redding dies and reamers in stock. Whidden still offer the dies off the shelf. Maybe he got his idea from the 22 Middlestead of the 60's (?) 308 necked down to 22 with a thirty degree shoulder, who knows? The advantage over the 260 rem and .243 win is a longer neck, no capacity increase. I'm using .308 Palma brass necked down for my 6.5 SLR.
How does the 6.5CM compare to the 260R in it's ability to work with a wider range of powder burn rates?
Would going with the 260R open up a few more powder options in finding a workable node or being a little less finicky than the 6.5CM? I've seem data on the 260R using everything from Varget to H1000. Can the 6.5CM do the same?

Often, a smaller case within the same caliber is generally easier to tune. I don't think either one really has a history of being finicky, if anything, they're both regarded as being pretty easy to tune. The 260 has been around a little longer so shooters have had more time to try different combinations but other than that they are just so close to being the same.
I must say, a 6mm 80 grain bullet at nearly 4,000fps is appealing. I'm not gonna say it isn't true but those speeds from that capacity is impressive.

Not been my experience.
There is always someone out there that will win with anything they have in their hand. If you were to give someone new a suggestion, would it be a 6,5 Creed or a 6mm to start out with?
My suggestion would be for a 6mm GT. For the reasons stated in my first post.
I am sure in different parts of the USA there are variations on equipment for PRS. In the South East the 6mm are way more prevalent than any occasional 6.5mm in PRS which is what the OP is asking about. I was hoping to help him make some decisions based off what is being used mostly in matches. Ultimately he will go whatever way he is going to go.
Hope this finds you all well.
