6.5 something

[RockyMtnMT]

Talking with @GLTaylor about building a 264 cal that would be beltless in the 70-80 grains of powder capacity. Need to have good quality and available brass. Thoughts?

 

[JMW67]

You must be looking for 4000fps with the 123 pretty scary

 

[RockyMtnMT]

Beltless in the 264 WM type capacity. Does Rich Sherman have a cartridge in this size?

 

[RockyMtnMT]

6.5 Dakota?

 

[JMW67]

neck down the 30 nosler i think peterson is making brass for it now and you can call it the 6.5 steve instead of the 26 nosler

Would 6.5 LRM be too big?

You could look at RCC, they can make anything you want.

6.5 RPM is super close to your specs.

Neck down a 7 rum. It will end up being a little more than 70-80 grain capacity but you will be able to build a heavier, longer bullet to accommodate.

 

[Corvalliscory]

Still think 30 Nosler as it's a little less capacity than a 28 Nosler

I was wondering if a 375 Ruger could be necked down since it has always intrigued me from case volume.

You'll need a very slow burning powder you can't find right now, a bonded , high ballistic coefficient bullet that holds together at close range yet expands reliably at lower velocities, readily available brass and better put creedmoor in the name somewhere or it will never work! Lmao!

SST. 70 grains
SS 73.5 grains
Max. 77.4 grains
Sherman 76 grains
All have available
head stamped brass
Both the Sherman amd max will hold around 70 grains of dense powders and the SM holds 90.
I client recently built a 26 SM and ran the 156 Berger up to 3508' I believe.

Well he owns Hammer Bullets so I think he has the bullet part down . . . Maybe call it the 6.5 Bigger Creedmoor or BC for short?
