I've been doing alot of research for my next precision rifle and after reading through all the different 6.5mm cartriges, I really like the 6.5 SLR.

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

What I'd like to know is if anyone here has tried this calibre and if anyone knows where to find the dies and reamer for it.

Thanks!

Is that the 243 win pushed back with a 30 degree shoulder? I was thinking of getting reamer.

It is the very interesting 6mm Super LR necked up to 6.5mm!
The idea is to have a 30 degree shoulder angle and a long neck like 6mm PPC.
6.5 Super LR is an "improved" 260 Rem to get more velocity, improved accurary and longer barrel life.

Good idea but is it worth it, the 6.5mm field is getting crowded!

Looks just like what we called a 260 RCBS Improved 25 years ago, more recently Jerry Teo renamed it the 6.5 Mystic, he may have altered the shoulder angle a degree or 2. in a 40 degree shoulder it has been called 260 Ackley Improved, again a cartridge that was all things a cartridge should be, 20 years ago.

Try as 1 might it is REALY hard to invent a new caliber, so guys just rename old 1s and call em new, so it must be better.
 
The reason why Im interested in this more than the 260AI or 6.5 Mystic is because the brass prep seems very easy and cheap. I'm hoping I can find a reamer and dies that wont cost me an arm and a leg!
 
One that might interest you is the 6.5extreme. (6.5-300saum) I believe it`s pushing 140 bergers to around 3000fps with a non compressed load of retumbo - about 60 grains (26 inch barrel)
 
6.5 launched from ??????

With all components being EQUAL does it really matter if the shoulder is 26,30 or 40 degrees??? The 243 win will shoot as accurately as the 243 Ackley. The real question,,, will the 6.5 compete with the 6mm caliber? The 6mm is the more accurate caliber, less recoil.
Enjoy. Bill

When I can push 140 Bergers or 142 Sierra's to 2950 with 48.5gr of H4831SC and get 2000+ rounds of accurate barrel life in my 6.5-08 why would 1 want to shoot 12+ more grains of powder, get 1500 accurate rounds out of a barrel, have a hard time finding decent brass, go and find a magnum boltface action for a mere 50fps more?


To the OP: 260AI Match Dies are easy to come by, 260 Lapua brass can be used for fireforming and will perform identical to the 6.5 SLR
 
What is the concern about fire forming? All you need to do is fire a round in the chamber and bingo, you are fire formed.

You don't need expensive bullets to do it, though you will want to take some time in the shooting to get a sizable quantity of brass without torching your barrel. Once it is done, it is done.
 
You will have to fireform the SLR or AI brass either way and the dies for the AI can be purchased from most anywhere.

If you don't want to fireform then go with regular .260.
 
Im under the impression all you need to do is run it under a sizing die, and if using Lapua or Nosler brass, turn the necks to get rid of the doughnut.

For an easy “no neck turn” brass option with no initial trimming either, use a chamber reamer like one of those shown on this page with either Winchester brand .243 Win. brass (the author’s favorite) or Remington brand .243 Win. or .260 Rem. brass. Both of these brands of brass have shoulder metal that is right around the same thickness as the neck metal of the brass, so that when you re-form the shoulder of the case there are no “donut” issues.

You will still have to fireform to the final dimensions.

I just took a closer look at the 260 vs the SLR and you will probably get the shoulder to 70-80% of final dimensions.

At first look I thought the shoulder was blown forward but I see now that the neck/shoulder junction is pushed down.
 
I just built a 6mm super lr a couple months ago and it shoots like a dream.
As far as fireforming goes the casings are the corect dimension when they come out of the fl die ,they shoot great from the get go.
Once fired I only neck size but they shoot good on the first firing except the ones with neck runout but these are easy to weed out and use them for fowlers.

The 6.5 super lr version does peak my interest also ,but for now I will play with the 6mm version .
The 6 slr will push berger 105's hunter with a bc of .545 if I remember correctly to 3200 fps using H 1000 and cci primers ,at 200m they will go in about a 1/2" so I'm not complaining.
 
I'd like to get into the 6mm game but I plan to hunt with this rifle and I dont think I can go much smaller than 6.5mm. Glad to hear the 6 slr works well!
 
At the risk of getting jumped on again by someone that I`m not responding to I`ve gone a similar direction with respect to a target/hunting 6.5 cartridge. I have had a 6.5-06 built. You can use 25-06 brass run through a 6.5-06 die in one pass and you`re ready to go. The brass is easy to find and I believe that it`s a fairly common chambering to help keep your build costs down. I`m getting about 2840 fps with 140 bergers and it shoots under an inch at 200 yards on the first resize from 25-06 brass. That`s out of a 24 inch tube and from what I`ve learned I think you could probably get close to 3000fps if I switched to H-1000. This might be of interest to you if you don`t mind the longer action.
