Whose running the 6.5mm Super LR?

[6.5BR]

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

Disregarding Lapua 260, this round does look like what the 260 SHOULD have looked like all along, vs. the Creed or 47 IMO.

Anyone running it? Thoughts?

Re: Whose running the 6.5mm Super LR?

It looks like a nice cartridge. I'd just go with the 6.5 Creedmoor for a few reasons.

You can still get great velocity
The accuracy is definitely there
The 6.5 CM shoots great in short barrels
Good factory ammo is available for a great price
Factory ammo shoots extremely well
6.5 CM is slightly shorter allowing you to fit into magazines better and chase the throat longer shot after shot


If your look at barrels as a consumable item (which they are) and are focused on performance in a short action repeater, then it sounds like it would be the best option. But if you need factory ammo, and want more flexibility then the 260 and 6.5 CM would be better.

Just my thoughts.

Re: Whose running the 6.5mm Super LR?

In regard to the 6.5 creedmore, I like the idea of a short barrel{18") hunting rifle. How do you think the 6.5 creedmore will perform at 18 or even 20" ? Any ideas of what powder burns best in the shorter barrels ?

Evidently you have never seen a 260AI

Re: Whose running the 6.5mm Super LR?

It sure does look like a 260AI. I wonder if it has the same ballistics?

Re: Whose running the 6.5mm Super LR?

260AI has a slightly higher case capacity (1-2gr depending on brass), a 40 degree shoulder and requires fire-forming. 6.5superLR has a 30 degree shoulder and no fire-forming of brass.

From what I can tell.

Sure.....just asking about the SLR.......has a longer neck it appears.

I have a 6.5 Creedmoor with a 25 1/4 in. Hart 1-9 twist and I have averaged 2744FPS with 42.0 Win 760.And with 40.0gr R17 I averaged 2646fps.Both of those loads are 1.5-2.0gr off published max loads.

Re: Whose running the 6.5mm Super LR?

Nothing wrong w/Creedmoor and brass/ammo cost may be easier and surely less $$ here in the USA, yet w/Lapua 260 brass, not sure how it will do commercially over time.

The SLR surely is a wildcat but I do think it's design has some nice qualities and being an '08 case is not a handicap for brass choices.

Thanks.

Re: Whose running the 6.5mm Super LR?

Interesting cartridge, it does offer a few benefits though I think they're not a significant gain.For a new build if you handload...maybe, especially if you like new and different.But if we're talking changing over from one of the other proven 6.5's it doesn't make sense.Being essentially a wildcat it also runs the risk of never catching on and fading away like so many other esoteric cartridges...

Re: Whose running the 6.5mm Super LR?

i built one and posted the results here. you can search my previous posts and find them. i used a 6.5x47 reamer run in deep. the rifle was then rechambered to .260AI because i thought i could push the big bullets much faster. well, either will make 2900+ with the 140 but the superLR will do it with less powder at a shorter OAL and NO FIREFORMING. if i can find someone who wants a medium palma contour barrel for a surgeon receiver in .260AI, i would gladly build another 6.5 superLR. truthfully though, since you have to form brass, you can do the same with the creedmoor with just more trimming involved. it is the best solution in my opinion WITH ALL THINGS CONSIDERED.

Re: Whose running the 6.5mm Super LR?

Back when the article on the 6mm LR Super came out on AccurateShooter.com, I emailed Robert Whitley about it and asked him about its application to the 260, 7mm and 308. He said that he had not tried the 7 or 30, but the 6.5 ran very well so altered. His basic conclusion was that the LR would run at the same velocities of a hard pushed unaltered case, but with more consistency due to the shoulder angle and less throat wear due to the longer neck.

Yet another way to skin a cat.

Re: Whose running the 6.5mm Super LR?

Interesting, no doubt, in the end, they are likely all more similar than different in performance.

Accuracy differences would be of interest if any w/SLR vs. say Creed, 260, etc. I wonder how the shoulder and neck improvements of the SLR help - or if not by much, accuracy, or ease of load work.

I do know in my experience for instance, the 6mm Rem seemed to edge out many 243s I have worked with, though never had a bad shooting 243. I attributed case design in favor of the 6 Rem.

Re: Whose running the 6.5mm Super LR?

Didn't think there was much of a gap between a 6.5 Creedmoor and 6.5-284, but it looks like someone's filled it anyway.

 

[xdeano]

Re: Whose running the 6.5mm Super LR?

So is barrel wear close to the creedmore/260 or a bit longer life due to the longer neck, pushing that heat a little further into the barrel. 3000-3500?

Re: Whose running the 6.5mm Super LR?

Close to an AI design. So I'd assume you'd get better case life than with .260.

Re: Whose running the 6.5mm Super LR?

I absolutely love this cartridge. Sure it's around the same performance as 6.5-284/.260AI. But it offers it with advantages. No fire forming, strong case design, long neck, and good performance and you can do it with a short action. Not that you can't with the others, but if i were to have a 6.5-284, i would put it on a Long Action, the 6.5 Super LR i feel i could use in a short action with the elongated neck. I like it alot. And when i rebarrel my .308 or build another rifle this will be in the run for the cartridge i choose. But i'm a tinker i like to reload and all. In the sense that Gordan pointed out the .260 or creedmoore would be far more practical.

 

[Jerkface11]

Re: Whose running the 6.5mm Super LR?

You form it from .260 brass so there IS fireforming. You're blowing out the taper and changing the shoulder angle.

 

[5RWill]

Re: Whose running the 6.5mm Super LR?

Reading the article he says all you have to do is run it through a full size reloading die and you have your brass. Am i missing something? Not trying to argue just wondering.

 

[Jerkface11]

Re: Whose running the 6.5mm Super LR?

Looking at the picture the case is pretty much straight walled. I assume you run your brass thru the die and you're ready to go but it still blows the taper out of the case when you shoot it.

Re: Whose running the 6.5mm Super LR?

Technically you fireform *all* new brass to one extreme or another. Usually blows the shoulder forward a few ten thousandths. But my understanding from reading the article, the sizing die forms the new shoulder, so in essence it *is* different from fireforming AI brass where there is a large airgap to fill, and a significant increase in H2O volume. The tapered case would also blow out a little. But the 6.5 S LR should be *much* closer to end product than .260 AI before first firing.

If I didn't already have a smith and a reamer lined up for my .260 build, I'd seriously consider this. I always wondered why the .260 came with such a steep shoulder and this is very close to how I envisioned it should have been done (I would have gone with a slightly shorter neck for increased capacity though, but then it would have been more like forming 260AI).

Re: Whose running the 6.5mm Super LR?

if anything you could make the neck a bit longer, it'll push the fire up the barrel even further. I've shot some wildcat rounds that have an unreal long neck. It increases barrel life because it's not torching out the throat as bad. I'm going to do a bit more research on this round to see what kind of info i can find. I'd really like to know what barrel life would be. The wildcat that a buddy shoots is a 6.5 and he's got well over 3K out of his barrel with very little loss if any in accuracy, and it has a lot left in it, from what the scope says. If I can get 3K out of a barrel I wouldn't mind giving this round a try, it seems like a very efficient round.

Re: Whose running the 6.5mm Super LR?

I realize it's going to get fire formed to the chamber when you shoot but when i say fire forming i mean it in the sense of having to blow out the brass to actually get near your final product formation like the .260AI. What i find is hilarious is a friend of mine has a .243AI and his Fire form loads are putting 5 shots in 1 hole and it's just a blowout load. It's a bit weird. So in his case should he reform his .243 AI brass back to .243? I wouldn't but he certainly has found an awesome load.

That new 6.5Lr look very intresting.Something I will definetly look into.

I had planned to have a 6.5x47 lapua built in a couple of years. And re-barrel my 700 to a M40/M24 contour in .308. I'm now contemplating just getting the next rebarrelling in 6.5Lr. Figure i could just reform my .308 brass to 6.5Lr.

Re: Whose running the 6.5mm Super LR?

Well I ponied up for a reamer and a couple of barrels now that tax refund has come. If anyone is looking for a smith with it in stock soon and cut rifled barrels in stock I can point you in the right direction.

Re: Whose running the 6.5mm Super LR?

Any More Field Data about this cartridge?

 

[Emilio]

What barrel lengths are you guys running?

 

[buffybuster]

I'm running my own 6.5mm wildcat that predates the 6.5SLR, but with very similar dimensions. Mine shoots 140's at 2900fps with ease from 23" barrel. That said, with the 6.5mm Creedmoor now out, there's little reason to do it.

I'll continue with mine, since I have the reamer and the gages. If I didn't have that, I'd go 6.5Creed. My opinion.

 

[Rockfish Dave]

Looking at the picture the case is pretty much straight walled. I assume you run your brass thru the die and you're ready to go but it still blows the taper out of the case when you shoot it.

Nope, the taper is not changed in the original Super LR.

The version I made does have the taper blown out somewhat. Speaking from experience this is no different than reloading for any other cartridge. I run the case through the sizing die, load and shoot... repeat as often as possible. I also shoot the 284 Shehane and it is the same process.

If you are a hand loader this is definitely a notch above current offerings but if you don't reload then it should go without saying you are stuck with the factory calibers.
