6.5 something

[Tidus56]

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

7mm lrm is a 375 Ruger necked down I think.

6.5 Dakota?

That would be Kirby's 6.5 Allen Xpress.

6.5 Thor Hammer?

6.5 Thor Hammer?

At one time (might still do it), I considered building .264 Thor/6.5 Thor/6.5 STW >>> https://www.longrangehunting.com/threads/264-thor.14874/

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.

Rich,
I have 6.5 Max brass on order. Will it hold 77grs of powder? If so. I'm on the way and didn't know it!

No! It will hold 70+ of dense powders.
The SM will hol 90

Ok, I'm confused. What is the SM (?)

 

[okie man]

Long action or short?

Sherman Magnum based on the 300 PRC

Sherman Magnum based on the 300 PRC

Straight Jacket Armory has the reamer

That should satisfy the need for speed! I loved my 257 wby and though a 6.5 bullet at those speeds would be sweet.

 

[GLTaylor]

So, you offer a 6.5 Max and a 6.5 Sherman Mag?

..........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.....

The current 124 Hammer Hunter started at 3960 fps, is still over 2000 fps at 1000 yards. A case capacity in the stated range is a bit elusive in readily available brass. With one of the Shermans being the only one I'm aware of. RCC can be a bit of a wait, but such projects move at their own rate.

While all possible variants haven't been tested, a mono 6.5 heavier than the 140 +/- grains currently available certainly isn't a given, and from a practical level may not offer much performance advantage.

Steve already has the reamers for the larger RUM case, as well as, Lapua, and Norma variants. Knowing the rifle platform specifics, and end use could be helpful.

The powder situation is a bit better these days for the over bores.

Put a rim on it and I'm in!

Good Luck GL!
