.260 rem question

I am planning on building a .260 rem. I would like to shoot 140 gr. Bergers through it. Will the COAL needed to load the Bergers fit into a standard short action and AI style mag? Or will I need the long action and .300 WM magazine assembly?

Good question...
But IMO, if I were doing it and needed to go LA, I'd ditch the .260 and go with the 6.5 x 284 Norma. Roughly 250 fps more...why not use the boiler room?

Barrel life might be a bit shorter, but I doubt significantly so.

From what I've read, the VLD's in that weight touching the lands won't work in SA mag length- but no first hand knowledge.

I have the same goal, to build a 260. I don't want a 6.5 x 284, I want a 260.

I'm going to build mine on a M-70 LA. Did some research, I can load them as long as needed with the M-70.

Now to just find a donner action.

Found one at the CMP auction site. A target M-70 missing the boat. Got the. Rifle, in 308 but turned out to be a shooter.

Now I have another 308 target rifle and still need another M-70 a toon for my 260 Rem.

Yes will most likely just stick to the .260. If a long action is what I'll need then no problem. 1 more question...so about the mag assembly. Will loaded .260 rds feed through a .300 WM mag? I am assuming if I need a long action then I will need a mag to fit that action.

The 260 will fit any magazine the or 30-06 will. The 300 Win Mag might be a tad wide. Don't know and can't check since my Model 70 300 WM is a single shot.

Have to try it in a magnum magazine action and see.

I shoot the 130 gr & 140 gr berger VLD's out of my DPMS LR260,and load them to Magazine length 2.810". They shoot great out of it.
I also shoot them out of my 6.5 Creedmoor bolt action,and shoot them at .010" off the lands at 2.877". They are still well under the maximum magazine length with the Creedmoor,but would probably be too long if it was a 260 since the case is longer.

The older Berger bullets really needed to be seated long,but the newer ones work at different seating depth's. It all depends on what your rifle likes.

Txhillbilly nailed it with this statement, though unsuspectingly. The 6.5 Creedmoor is the ideal cartridge you are looking for.

The short action can be found with two lengths magazines, one is about 2.8" and the other is 3.125". The former might be too short for accommodating a high BC 140s, the latter will be just fine. So before ditching the SA, see if you can fit a longer mag.

I think it would be a bit of a waste a .260 on a LA, better options for that...my favorite is the .280 AI but you're stepping up to a 7mm.

If you are really set on the 6.5 and LA maybe a swede would be a great choice, if you hand-load. The 6.5-284 shoots really, really fast and barrel life is not the greatest.

The 6.5 Creedmoor and 6.5 Lapua are other options for SA, with the Creedmoor being virtually identical to the performance of the .260 and it will fit the short mag.

IMO, the .260 is the perfect caliber for the .308 brass, not as fast and barrel burner as the .243 and not sluggish like the 7-08 and .308.

From everything I've heard the 260 will have double the barrel life of 6.5-284 and you can get the velocity closer than 250fps with the 260.

You could also look into a plain 284win.
If you were going to end up with a long action its a round to consider, can get great barrel life and up to 2900fps with some very high bc bullets.

Check the price difference in brass between 260 and Creed. You're paying for marketing, not performance. Don't complicate the obvious, LA and 260; however, my SA Savage 16 shoots better as I compress the charge(s).

WHAT? 6.5 Creedmoor Hornady brass is $34.99 (50 count) or $0.70 (for each individual piece of brass) and Nosler is coming out with brass for $64.99 (50 Count) or $1.30 each. Remington 260 brass is $14.99 (20 count) or $0.75 each, Nosler is $61.99 (50 Count) or a $1.24 each, Norma is $24.99 (20 Count) or a $1.25 each, and Lapua brass is $109.99 (100 Count) or a $1.10 each. Yep, you are really paying for that marketing (sarcasm).

The 6.5 Creedmoor was designed off the .30 T/C, which is a shortened .308. It has a 30 degree shoulder, and the body has less of a taper compared to .260 or .308. The shortened length of the case is what makes this cartridge excel when it comes to the longer 140+ grain bullets. The shortened case allows these longer bullets to be seated with less intrusion into the case compared to the .260. When you subtract bullet intrusion from the .260's case capacity with these longer bullets, the .260 has a minimal 0.7 grain advantage. When you combine the 30 degree shoulder (20 degree shoulder in .260), reduced body taper, and shorter case length you get a more efficient cartridge that burns less powder and gets the same numbers as the .260. If you reload, that means more bang for your buck. If you don't, the Creedmoor Hornady ammo is less costly compared to the .260. Hornady offers match ammo in 120 and 140 grain A-Max and cost around $26/box. Nosler will start producing ammunition for the 6.5 Creedmoor this summer. One of Nosler's 6.5 Creedmoor loads will be match ammo ($40/box).

The rounds are pretty much identical in performance and ballistics. For my use, if I had to choose one over the other (I already have a 260), I'd probably go with the 260 due to the ease and simplicity of making cases by necking down one of the most available cartridge cases on earth, the 308. Any cartridge length advantage the Creedmore has only comes into play with the heavier bullets, which I don't shoot. But if I did shoot just the heavier bullets and was into long distance shooting, maybe the Creedmore would be the better choice by a small margin. I'd be happy with either.

For my 260 Remington,I resize 243 Winchester brass,and don't have any problems like you can get from down sizing 308 brass-Neck turning or shoulder donut.

You can resize 22-250 brass into 6.5 Creedmoor,and some guy's are resizing 250 Savage brass for it also.
I like both calibers,and the performance is almost identical between them.

To all the people who claim the 6.5X284 to be a barrel burner, mine has 1,100 to 1,200 rounds on it and still shoots 5" at 1000. (most of the time anyway) Shoots as good now as it ever did. It might go to crap tomorrow, but definitely not what I would consider a "barrel burner."

Any discussion of 6.5-284 should include the 6.5-06.

Yeah, it is a wildcat, but barely so. All bullet and powder manufacturers list load data, dies are available off the shelf, and brass can be made by neck sizing 25-06 with no other work involved.

It is the ballistic equal to 6.5-284

Actually you can load the 6.5-06 hotter than then 6.5-284 for some crazy velocities within 100 f/sec of the .264 magnum!

I am of the opinion that the .30-06 case is just perfect for the 7mm.

I agree...
My next action is gonna be a long one...
I use the 162 Amax (.625 BC) in my 7-08... pushing that boolit out of a .280 case would be the ticket

There's so many choices with nearly identical ballistics in the 6.5's being discussed that I doubt 95% of the shooters here driving the rifle could tell the difference. Pick a winner, as the saying goes. You'll be happy with any of them.

Well, George, compare apples to apples. Rem Brass from Midway is $53.99 per 100, Norma $109.99 per 100 and Lapua 109.99 per 100. So, what are you paying for? Same capacity, same performance. BTW, if I want more performance, I pick up my 6.5-06 or 338-06. I make those from '06 brass.

Well, George, if you want to pay $53.99 for Remington brass (even if it is a 100 pieces), more power to you.

BTW, when I want exceptional performance, I pick up my 6.5 Creedmoor!

Gorsh, I didn't know that a Creed could push 120s to 3180, 129s to 3070, and 140s to 2935 at the chronograph! I'm re-barreling my 6.5 right away!

My Creedmoor must have missed that memo, because its not nearly that fast.

GeauxTide, I used to love Remington and Winchester brass. That is until I started using Norma. Norma is worth every penny it costs; especially if you run the pressures up real high.

Well if you only associate speed with performance, then you might as well get a 6.5mm STW and call it quits.

I get it George, the .260 is the bee's knees of the .264 caliber, followed closely by the 6.5-06. I shall rue the day I bought the 6.5 Creedmoor. Scorn the 6.5 Creedmoor for the audacity to be a more efficient and for having a modern case design. Scorn Hornady for actually doing research and development, instead of necking down a existing cartridge and letting it flounder.

So let us all give three cheers to Remington for their vast selection of rifles chambered in 260 and keeping cost down by sparing us the marketing campaign.

Geo, I own a Creedmoor and I like it. Having said that, there is nothing super wonderful about it. It is for all practicalities purposes a .260 Remington. Pretty much all Hornaday did was neck up a .22-250 and lose a couple degrees of taper. There is nothing ultra modern about their design.
