What cartridge for the new bullet and why? I'm thinking about building a rifle around this bullet next. What do you all think?
What cartridge for the Sierra 150 grain 6.5 bullet
- Thread starter demonjigger
- Start date
If pure performance is your goal(not prs) I would guess a SAUM or 6.5-284 maybe? I would think those two would excel pushing that heavy bullet.
Yes, that is the decision to make. I'm guessing that a creedmore would not be able to push it fast enough to see any benefit. I have some cartridges in mind but I want to see what others think. I have no experience with the 6.5
And mercracing you named 2 of the 3 I was thinking of... I'd like to see3100-3150 fps with a 26" long barrel or so. I saw some loads with 140's that were in that fps range so I don't know if it's possible
I’m not nearly the smartest guy in the room, but I would think to see the awesome BC, you need speed. I’ve seen people run the numbers and they seem to be ok but I would think the two I listed would make that bullet shine if you push past, or right at the top of PRS speed.

With that bullet, one heluva combination! Key will be getting the rifle weight and muzzle brake together to mitigate the recoil.
Having watched ROs miss the call on a 6 Dasher hitting a big solid plate, this combination would make it very obvious when the round hits a target.
Getting ready to rebarrel a rifle, this may have just changed what it is going to be!
These would be the two most likely calibres, I can see a few F-Class shooters giving this a try.
What cartridge are you talking about? The subject is a projectile, not yet associated with a specific cartridge.
I thought the same thing but Sierra usually post stepped BC’s
and this one is no different. They are claiming a .713 BC if pushed 1760fps and faster (which is easily done in any 6.5 application) and a BC of .686 between 1240-1760fps. We will see but a lot of people doubted the 110 SMK but it’s proved to be exactly what is advertised so hoepfully this one will as well.
My third choice was the 26 Nosler. That would be a long range steel rig and possibly hunting(with a different bullet). I guess there will be more discussion when the bullets hit the shelves.

Those are very attainable speeds for any 6.5 to be sure. I only meant if you took your SAUM, .284, or Nosler and loded these you would be at a much greater distance before dropping to these speeds.
I was wondering why they didn't list BC's for higher speeds too? 1760 fps seems slow to get the max BC, right?

Next barrel for my 6.5 Saum will be a 7.25 twist, until then I'll stick with the 140 hybrids for my 8.5er. Only a couple more years to go..
A question for those that know. How do the 6.5 Saum compare to say a .260 Rem as far as ease and speed of feeding? Single stack AI mag or AW okay?
I know that the obvious answer to the first question is that the steeper shoulder of the Saum is not a slick feeding as the 260, but actual experience is always helpful.

Jeff Brozovich over at Long Range Only is testing the new Berger 155 in a 6.5 creed and he is seeing benefits of higher BC out of the 6.5 creed at distance. Check out the thread over there.
I look forward to trying the new Berger or Sierra in my 6.5x284 as a hunting bullet.

Bates762, did they say at what altitude by chance? I have had bad luck pushing the twist rate at 1300' above sea level...
Hunter223 can get 4 groove cut rifled Mueller Works Barrels in custom twist fairly quick. Placed my order for the 1-7.5 twist and was quoted about 8 weeks. He’’s gtg with fast shipping once it does come in.
Likely to begin with 4831SC .
I know some guys that get along with Retumbo with the 6.5x284 but have never tried it.
This is the bullet I'm having my 6.5 SAUM built for. I am hoping to use a Proof Carbon but they only cut the 24" Lite Sendero with a 1-7.5" twist. I just wrote back to them today hoping to get a special order of a 26".
Just ran a few of these through my 8 twist saum
got 3135 before pressure showed up 26" using Retumbo
nice node around 3100 will shoot for groups tomorrow

I found they liked a bit more jump than I had originally started with 25 thou off was Money , I am going to run 60.5 Grains of
Retumbo which clocks in at 3080ish es of 8 and sd of 4.6 for 5. Shots.

There's a guy on accurateshooter that tried to run them in his 6.5-284 and was blowing up bullets in a conventional rifled Krieger barrel. Sierra and Krieger worked together to figure the bullets won't take that speed with conventional rifling.
Other than him I don't know of anyone pushing them hard

This is good to hear, I’m building one right now with a 28” pipe. Was hoping for good results with the 150 smk. What coal length did you end up with and does the b.c. On the smk seem to hold up at distanceI am getting 3156fps from my 26" Bartlein 1:8" in 6.5SS w. the 150 SMK. Ridiculously accurate round. They are hot for sure, right on the edge, but they are a laser beam. I have 4 loadings on some of my brass already.
