6.5 something

[Paper boy]

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?

Absolutely is thinking along that line myself

I had a 6.5 RPM built on a Kimber Montana 84L, lengthened the mag box and added a 24" #2 1-8 twist Benchmark and it's shooting the 156 Berger's into the same ragged hole at 3070 with 65.0grs of R26/BR2 primers

Slight Pressure signs at 66.5grs of R26 at 3148fps

Necking down a .270 WSM would be cheap way to go and get you really close to the mid 70's powder charge. Probably would not even have to neck turn the brass.

I have this exactly. 6.5 wsm has been great so far. I have used Retumbo and h1000. Everyone is gushing over the 6.5 PRC but Winchester case design is just as good and efficient. 270 wsm brass is easy to form with one pass and no neck turning. Even though neck turning is always good. Dies are easy to come by (270 wsm die with a .297 bushing) and the seater dies work just fine with a 6.5 seater plug. 63gr of H1000 pushes that 147 eld-m to just over 3k. It can be pushed to about 3150 but then the bolt becomes a bit sticky. That's all with a 23" barrel.

You're thinking of the 257 Blackbird that's a necked down Blaser. The Blackjack is a modified and necked down 7 SAUM

My mistake. It looked good but I did the 25x6.5Prc. The blackbird looked like too much of a good thing.

I get quite a bit more velocity from my 65 SS than the two 6.5-270 WSM I built.

I'd be looking at the 26 SM.

I have a 338x375 in the build stages , Its a new spin on a 33 Newton

How far are you into it?

Sherman just came out with the 33 Sherman which is a .338/300 PRC Improved.

Good morning Fellas , My 338x375 is well on its way , PAC NOR is making the barrel 1 in 9 twist with a 5" chamber , straight taper to .800 , 34" Polygonal rifling , a P17 Eddystone Enfield action set up it's getting a Remington magnum length box installed , a Timmney trigger and I'm waiting for the Brazilian Walnut to arrive for my gun stock .
