Remington 260...The new Sniper rifle?

Hey everyone,
I have been doing some research on the Remington 260 and from what I have seen it is a pretty impressive round.
Here is a article I read on it-
The Case for .260 Remington: A Better Cartridge For Practical Long-Range Shooting
It seams like this would be a great overall round to use for Competition/Hunting/recreational shooting.
So what is the over all opinion on this round? I am seriously considering converting my Rem 700 243 to this caliber. Please give me all the info/opinions you have on this caliber so I can make an educated decision.
Thanks in advance for all your help,
Porter

Re: Remington 260...The new Sniper rifle?

I always love to read these articles that claim this cartridge or that cartridge blows the 308 out of the water. Again we read of mountains and mountains of "paper" ballistics.

In the real world the 260 can have a slight performance gain at 1K over the 308. Blow it out of the water? Hardley. You gain a whopping 12" of trajectory and a whopping 18" of less drift in a 10 MPH wind and a whopping 83 FPE at 1K. What does this all meen at 1K? you still have to compensate for wind and drop and you get a smaller hole with less barrel life. With the 308 you get bigger, heavier bullets with more velocity than the smaller lighter ones. Out to 600 the 308 will do better, albiet slightly in 2 out of the 3 main catergories (drop, wind, energy). About as much as difference as the 260 over the 308 at 1K. That is minimal. What they fail to tell you is that in a 26" barrel you can get 3000 FPS with the 155 SCENAR. Also with a standard 308 12x barrel you get much less sideways torque than you do with the 9-10 twists used in the 260.

There is a reason you still see the 308 on the front lines.

Again, if you want to "blow the 308 out of the water" using a smaller bullet in the same old case is NOT the place to do it. If an idavidual wants to blow the 308 out of the water, use a bigger case.

My answer to this is. The only reason is to make the 7 RM look good. There is no other reason.

Re: Remington 260...The new Sniper rifle?

Thanks for that great reply. In the Army we always used the 175gr HPBT M118LR. This was "THE BEST" round for the 308 as far as the Army was concerned. You mentioned a 155gr bullet. Do you know what the BC was on that? I would like to run it through my ballistic program and see what that shows. Are there any bullets out there for the 308 that have a .6 0r higher BC?

The 155 SCENAR is published at .508 I have tested this and found it to be very close. As far as bullets in the .6's, several of the sierra MK and berger bullets as well as the 208 AMAX. Sierra has one in the .700's

Re: Remington 260...The new Sniper rifle?

Porter

I owned a 308 for 10 years, and have owned a 260 REM for the last 6 years.
My 308 experience was with the 168 SMK at 2700 fps. With my 260 I am running a 123 gr Lapua (BC 547) at 2950 fps. At the magical 1000 yard line the 308 looks like this.

168 @ 2700fps
Wind in MOA 10.1
Drop in MOA 34.4
Energy 441 ft lbs

The 260 like this.

123 @ 2950 fps
Wind in MOA 7
Drop in MOA 27
Energy 543 ft lbs

A 3 minute wind difference is significant . If you miss judge a wind call the 260 is more forgiving.
Run the numbers. the 260 beats the 308 across the board except in barrel life. I had my 260 barrel set back at 1700 rounds, the beggining of the lands and grooves were just starting to crack, the rifle still shot very well. Have around 2000 rounds on the barrel now and it still shoots .3-.4 most of the time. I am expecting another 1000 rounds till this barrel becomes a tomato stake.

260shooter,

That is all well and good except the 168 is anything BUT a 1K bullet. There are so much more to a 308 than a 168 SMK.

Dont get me wrong, I am in no way saying the 308 is superior to the 260 or vice versa. Superior is a subjective term. You still have to take into concideration other options.

Re: Remington 260...The new Sniper rifle?

Michael you are correct. If my main concern was shooting 800 and beyond, I would use something with more boiler room. I consider the 308 a good 700 yard cartridge and the 260 good for 850. Both will punch holes in paper very nicely to 1K.
As far as a new sniper cartridge the department of defense has come to it's senses and is looking at a .338 caliber cartridge (probably the .338 Lapua) of some type.

I have a 7MM REM MAG sitting at my gunsmiths ready to go except for a few pieces, that will fill the long range bill for me. Hope to launch 168 gr Bergers at 3000 fps or so.

I myself am very interested in JEFFVN's 7MM Holy Grail project. I am also impressed with the 7MM ALLEN MAG. They both have a lot to like (except a short barrel life in a military enviroment) . Both cartridges are more suited to a reloader/hunter type situation
