ok i haven't taken a huge amount of game with these bullets so here is a question for those that have. i was looking through my barnes manual and came across a picture with a lady taking a moose with a 100 grain triple shock out of a 257 roberts. do they really perform that well and if so am i thinking correctly in that a 130 grain out of a 260 remington with the proper broadside  shot would work just as well for moose,obviously there are better tools for the job but if you only had this rifle and this load at 2800 fps and were going on a moose hunt would you use it or not

I would not use a .257 Roberts on a Moose unless I could not handle recoil due to illness. We owe these animals a quick and humaine kill. I shoot till the animal is down; I don't wait to admire my first shot!

If you are confident in your shot placement, regardless of make of bullet, as long as they are a quality bullet,your .260 is adequate for moose. I have a friend that uses nuthin' but a Ruger #1, chambered in .22-250. He has shot several moose, many more elk then I, and they drop dead right were they stood when hit!
When I was a youngster, I have succefully harvest all that we have, with eather a ol' Krag or my 6.5 Swede, and I only used Hi-V Bullets, which were not really known for thier quality---Probably why they are no longer in buisness.
However, I'm not that confident anymore, so I pack a canon!

moose isn't an every year hunt maybe once every 5 or 10 even it just amazed me that a 257 roberts would penetrate enough to cleanly take a moose,while i know within my limits i could easily make a clean shot which here is probably at most 75 yards because of terrain it just didn't come to me that a caliber of that size is adequate for moose though i have read the 6.5x55 the 260's ballistic twin has accounted for more scandinavian moose than all other calibers combined i think i'll limit it to black bear over bait and deer size animals

... it just didn't come to me that a caliber of that size is adequate for moose though i have read the 6.5x55 ...

Yes, ther 6.5x55 has accounted for more moose than we'll ever encounter over here, but then they have much more rigorous hunter certification qualifications than we do over there, and they don't rely on big cannons to compensate for inadequate shots.  If you trust in your ability to put the bullet where it needs to go, the moose won't care if it's a .257 Roberts or .260 Remington.  If the shot shouldn't be taken, then no bullet will over come that.

The monometal bullets such as the Barnes TSX and Hornady's GMX do not act like a standard cup and core lead/gilding metal bullet (Remington Corelokt et al) when they hit the animal. The monometals do not lose any weight on impact whereas a cup and core will. So you can start with a lighter weight bullet, drive it faster, and still end up with as much or more bullet weight than a heavier conventional bullet. Plus they almost always give complete penetration.

Barnes (and others) increase the performance of each cartridge from what 'used to be'. So yeah, while you may have to pick your shot a bit more carefully, taking a moose with a 100 grain Barnes in a 257 Roberts is easily doable.  And the 260/130 combo would be fine, in fact if they have 100's you could probably run those and not have to worry.

ok so reading and reading about this something i've never paid attention to, my abolt is a 1 in 10 twist so does this mean it won't shoot heavier bullets accuratly or will it not shoot light ones correctly i'm thinking of either the 120 or 130 grain barnes triple shock as a mouse to moose load and running it around about 2800-2900 fps. before if i couldn't get a rifle to shoot the load i wanted i just got rid of it now i'm suspecting i should be paying more attention to rate of twist????

Bullet length not weight is the the critical factor. The monometals will be longer for the same weight bullet. The last I looked, Barnes had some information regarding which bullets won't work with certain twist rates.

For the most part, unless you are at the extreme ends of bullet weight for a given caliber, whatever twist you have will work just fine. The most common problems with slow twists are heavy bullets in the 223 and older Savage rifles in 250 Savage. Rifles can be finicky, lots of folks have good luck with 90 gr varmint bullets in the 270, mine never liked them. So I switched to 110's and had much better success.

When working up a load, I start with the bullet I want to use and a suitable powder. If I don't get what I want, I'll try another powder, then a third if necessary. Then I switch bullets if need be. Sometimes, if a load is close to what I want, a change in overall length will dial it in too.

I've never worried about twist.

edit:  Just checked, Barnes still lists a minimum twist for certain bullets.  In the 260, I think I would start with the 120 Tipped TSX and see what happens.  I've read that most Barnes bullets shoot better with a fair amount of 'jump' to the lands.

First of all you don't have to stay with Barnes bullets if you want non lead bullets you can go with Hornady or nosler and they both have non lead bullets for most rifles.. I my self have loaded for many years and have loaded for even old rifles and " The Only rifle that , I would not recommend loading the barnes bullets or any non lead bulltes for is the old K-98 german 8mmin 8x57 cal because they wont hold the pressure and will blow up .. I'm a retired USMC Sniper and , I know what will work and most that wont !!                    May , I ask what caliber are you wanting the data for with non-lead bullets and why do you want to shoot non-lead bullets .. Is where your hunting a non-lead hunting area..

First of all to answer your Question about using a 260 cal for a moose .. Yes, I would use the rifle .. And to your other Question : Shot placement is a major factor when shooting any large game with any caliber rifle that is a fact !!! I my self have shoot many very large game animals Like Big Black Bear in BC & in Alaska with a 223 cal rifle with a 75gr HP bullet and like , I have said shot placement is the main factor when shooting a small caliber rifle when huntiong large game.. And it had a 1-9 twist..

the barnes bullets are all copper as to hornady and nosler are guilding metal meaning the stuff cup and core jackets are made of, they are harder than the barnes and take more velocity to expand tried them proved this in many other calibers as i am not new to reloading i've been doing it myself for 20 some odd years. the reason i shoot barnes is the reputation and proven performance in other calibers for deer or other smaller targets i shoot sierras the 6.5 caliber is new to me never owned or shot one before today and since the 260 is a lower velocity round i will stick with barnes not to mention hornady and nosler don't make bullets heavier than 90 grains in the non lead bullets and they are much longer than the barnes....however running some factory rounds through the gun today remington 140 coreloks and 120 ballistic tips it looks to me like the bullets are comming apart on impact which i have to do more testing with...however i don't know why you wouldn't load unleaded bullets in an 8mm mauser pressure peaks out around 52000 psi which is perfectly fine i load them in a friends 8mm mag and have absolutly no trouble pushing the at 3350 fps and around 59000 psi. also i wouldn't go posting you hunt bear in alaska or bc with a 223 as last i checked anything under 27 caliber was illegal to hunt them with

The .223 is a very popular round  in Alaska. On page 19, paragraph 1, Alaska hunting Regulations, it states "You mat not use a rim fire rifle when hunting big game! Except, you may use .22 calibre rimfire cardtridge when takeing swimming carabou, in GMU23 and 26.."  This is the only calibre restriction listed in the Hunting Manual. I realize that there are additional restrictions that are not in the Hunting Regulations, that one needs to  go to http://www.wildlife.alaska.gov,  Many folks, do use the .223 and .243 for black bear.  Have never had any of the wildlife officers tell me that it wasn't legal.

i do apologize as i didn"t see black just bears but for brown bear atleast in bc there isa a 27 caliber minimum
