6.5 Super LR

Hi, looks like it can be run at the same speed as the 6.5x284, how is the barrel life? Any real life hands on experience would be most appreciated. Thanks.
 
I'd suggest you're better off thinking about variables like brass cost/brass life/ resistance to length growth/mag feeding.. rather than barrel life.

If you're driving the same bullet at the same velocity, you're gonna be within 5% of a identically-performing case design. Not worth considering.

True that! Mag length not an issue as I intend to single load, the angle of the brass suggest a better brass growth issue as compare to the likes of 243 or 260. Barrel life is a concern as one might spend a lot of time to arrived at a good load then the barrel go south ! I shoot several 6.5x284 and have to monitor round count so that I am prepare when the rifle suddenly behaved differently, I would have a handle on the situation. Hence my request for a hands on experience with this round. Thank you for your advice.
 
It never takes me that long to find a load! Last thing I worry about is barrel life. When they go, get a new one. The same load will probably work
 
Thanks for the advice! As a side note, if we are lucky, we might get into a good load very quickly but at time when nothing seems to be going right, infinite testing and frustration usually is the part of tuning a new rifle. A good friend of mine shot over 400 rounds in order to be 100% happy with his loads! He left no stone unturned ! BTW, that is a 308 caliber so plenty of life left on that barrel. Also, time off not shooting ( disruption ) while rebarrelling is a pain in the butt! Well, may be 6.5 Super LR is not worth pursuing as there don't seems to be much hands on experience at the moment.
 
After reading this: http://www.6mmar.com/65_SuperLR.php

I am very interested. If I didn't have a 260 REM already this would be my next barrel.

As for brass availability, from the link posted above:

"Making brass for the 6.5 mm Super LR is very easy, just take new .243 Winchester brass or .260 Remington brass, and properly lube the cases with a lube like Hornady One Shot spray lube, and run the cases in and out of a 6.5mm Super LR full length sizing die, and that’s it – your brass is made!

Load it, shoot it and have fun!

My favorite base brass for making the 6.5mm Super LR is Winchester brand .243 Winchester brass. Remington brand .243 Winchester brass or Remington .260 Remington brass works fine as well.

If .243 Winchester brass is used to make the 6.5mm Super LR, you need to lube the inside of the neck in addition to the outside of the case. I use a Q-tip and spray Hornady One Shot spray lube on the end and use that to lube the inside of the necks of .243 Winchester brass. The lube inside the neck makes it so the tapered expander ball that comes with the 6.5mm Super LR sizing die will easily and smoothly expand the necks of the .243 Winchester brass up to 6.5 mm. Once I lube the inside of the necks of the .243 Win. brass, I then lay the brass cases out on a piece of newspaper, side by side, and spray the group with Hornady One Shot spray lube (making sure the neck and shoulder area of the cases is adequately lubed)."

Sounds like availability is a non issue for me.
 
260 Rem is a good caliber, mine shoots the 130 grainers well. 6.5 x 284 of mine shoots the 140 grainers well. when I read that the 6.5 Super LR can perform similar to the 6.5 x 284 with the 140 grainers, hence my interest to dig further into this caliber, making direct comparison. Thank you for all your input, much appreciated.
 
Nik,

I started looking at these a few month's ago. From what I read, the throat erosion was reduced by the longer case neck. Maybe someone will chime in with more knowledge on the matter and can clarify or correct me in my understanding of the following.

"The 30 degree shoulder angle and the long neck of the 6mm Super LR is another potential benefit of the 6.5 mm Super LR. Not only does it help to avoid the throat torching effect that people associate with a short neck, but the 30 degree shoulder angle has also been a hallmark of some very accurate cartridges (6 PPC, 6 BR, 6XC, 6.5 x 47 Lapua, etc.)."

The longer barrel life, available brass (I have a ton of 243win lapua brass), accuracy and higher velocities really have me wanting to get a barrel spun up in 6.5slr.

The only thing stopping me is I have an outstanding 260REM Bartlien barrel already spun up that is a proven shooter, so I just cannot justify the cost and gunsmith hassles of getting a new barrel right now. When this one is toast, I'll just transition everything over to the 6.5slr.
 
Would a 6.5SLR reamer clean up a 6.5X47 chamber?? The case is longer and it might cleanup the throat as well and extend the life of the barrel without having to set it back.
 
If anyone wants to drop the $150.00 that JGS want for a reamer not to mention the 18 week turn around time, myself and my partner would gladly help defray the costs of it.

Did you look at the 260 improved 30? It looks like the same performance and an easier case to create. There appears to be no potential for a donut in the neck created by resizing the neck. You can also shoot 260 factory loads through the chamber.

Ordered a carbide Reamer, Go and No-Go Gauges this week.

I choose the 6.5 Super LR/S to run VLD's easily in AICS magazines and give me some flexibility in chasing the lands...

http://www.6mmar.com/65_SuperLR.php

From the website:

"For the 6.5mm Super LR/S Reamer above (i.e. with the .055" free bore, is throated for magazine feeding many of the 139-142 gr 6.5 mm bullets) the following bullet measurements were made to show at what OAL the noted bullets hit the lands:

Sierra 142 gr. MatchKing - 2.845" OAL
Berger 140 gr. LRBT - 2.838" OAL
Lapua 139 gr. Scenar - 2.808" OAL"

If you can make a 6.5 super buy running a 243win into a 66.5super die, it will only have the case cap. of a 243. If the super has 243 cap. it will hold 52.8 grains of water. How will it preform with a 6.5-284 that holds 65 grains of water? And if it holds that much less powder it will absolutly have better barrel life than a 6.5-284. But as the OP suggested, it cant "run with" a 6.5-284. The real question is does it need to run with one. I have a 6.5 -284 and if not for being set up with dies and such i would shoot a 260 ackimp on my next barrel job for that gun.
 
I agree with Ebb, there is no way that the SLR will run with a 6.5x284. The 6.5SLR may be a fine cartridge but its no 6.5x284.

The 6.5X284 will easily push the 140s to 3000fps you can NOT do that with a 260 sized case.

Whats the difference between the 6.5SLR and the 260 imp 30 degree in performance?? I see from the posting on Roberts sight it shows the SLR running 142s faster than the imp 30 degree with the same bullets and loads. This is confusing since the imp has a larger case cap. than the SLR.

Care to chime in Robert?? I just ordered a reamer for the 260Imp 30 degree so I hope I was reading the above wrong.

I would appreciate an answer on this question too! Maybe someone has done this as a upgrade for the 6.5x47?

I would think that it would clean up the chamber but you need to look up a diagram of a 6.5x47 and compare it to the 6SLR.

I had a 6XC and used the 6SLR to rechamber it and it cleaned up just fine.
