I'm thinking in terms of using a 140gr bullet at long range.Far surpasses it. 127 grain at 3150.

Yop. That’s how they wrote the saami spec.Yes but I think the 6.5 CM is a 1-8. Was done intentionally I understand for long range shooting.
It does everything better, case is just a hair bigger and will clean up a Creedmoor. You get 2-3 grains more powder capacity.I'm thinking in terms of using a 140gr bullet at long range.
She is "burned out" for lack of a better turm... I am going to rebarrel, but was just kicking around the idea of maybe changing things up a bit. I am not the least bit unhappy with the way it was. Just looking for ideas to ponder. I was always leaning towards keeping it a 22-250. I just wanted some possible ideas that I may not have come up with. Thank you for another vote of confidence! I will post on my decision but it won't be soon!So what was wrong with the barrel you had on it? Sounds like your wanting to change things aa bit from something that wworked to something you hope works better. If it wereme I'd stick with the facroty style 22-250 barrel but am sure I'd get a custom barrel.Only after market barrel I've ever used is Shilen and I love my Shilen barrels. I wouldn't bet something else would not make me happy though. A barrel is a barrel and I believe one is really as good as the next so long as the maker has a good reputation turning out good barrels! In all likelyhood if your looking for a barrel that shoot's tiny groups, go with experience and reputation. Then if you really want that a lot is going to depend on how you load the ammo and shoot. I just wonder how many of us could take a rifle with a barrel shooting .250" groups with an accomplished benchrester and shoot a .250" group with it. I have read in the past where Douglas barrels are simply not that good. Then read where they are! Tell ya what, they must be doing something right, I believe theyare still around! Pick a barrel from a maker that your confortable with and go for it. Opnions are generally worth exactly what you pay for them.
I have a Kimber in that...unfortunately it is not a shooter..yet!Have a Benchmark on a Weaver custom 300 WSM, very accurate.
It is heavy but here in Indiana shooting yotes and ground hogs it doesn't get carried far so no issue. Prarie dog hunting doesn't go far out west. So no issue.Obviously, your using the rifle on varmints.
But some missed questions still should be asked.
1) how far do you carry said rifle? While you may use it often, do you regret having to carry it?
2) Is there a different cartridge that you've always wanted, but don't have? Maybe the same parent case, but a different caliber?
3) How far are your realistic, typical shots?
4) Are you thinking double duty for the rifle?
Aka varmints, deer, antelope.
You can load a CM to near that. Unloaded case capacities are reasonably close, and loaded case capacities are essentially identical. I’m not convinced that anyone is getting meaningful increases in velocity with a 260 over a CM unless they are loading the .260 well beyond 2.800” and limiting the CM to 2.800”Far surpasses it. 127 grain at 3150.
Meaningless comparison using 260 load data, a AI holds 3-4g more powder especially if using a drop tube.You can load a CM to near that.

In the included Nosler data, the 6.5CM is loaded .025” SHORTER than the 260Rem, and yet shows .1gr more H20 capacity. Different. Randy’s of brass would show larger differences than that. Top MV is within 20fps between the two cartridges. The 260Rem, with a custom reamer, can be loaded .116” longer than a 6.5CM, and at that length, offers no meaningful case capacity increase over a 6.5CM loaded .116” shorter, BUT it won’t fit in a normal S/A magazine.
A 260AI does beat a 6.5CM by a little. The CM would gain almost nothing by converting to an AI.
Off topic, but it drives me crazy to read things like “a 6.5CM shouldn’t be used on elk.” Followed by recommendations of a 7-08 with 130-140gr bullets. So you’re saying that roughly the same case capacity, but with a bullet of lower SD and BC is better? Ok.
I missed that Don said “AI”. I thought you two were talking about a 260Rem with an 8” twist.Meaningless comparison using 260 load data, a AI holds 3-4g more powder especially if using a drop tube.
What difference does the case make…Can a 260AI outperform a 6.5CM. Yes, definitely. My comment was misdirected at a comparison between a 260Rem and 6.5CM
Exactly why I am staying with the RUM and not going PRC or .30 Nosler. mtmuleyI already own the cases, dies, rifle. Why double my expenses for essentially the same thing. All done when the .260 Remington came out and the AI and CM didn’t even exist.
Goog questions. How far would I carry the rifle. Beginning to end. If the rifle at even 8# is to heavy, I don't really need a lighter rifle, I need excersize!Obviously, your using the rifle on varmints.
