6.5 Needmoor ~ Federal +Peak

The question is whether the primer will fail under the pressure. They have made improvements to the case but have there been a significant change to the primer cup to take the new pressures.

Well that is a Fact as primers normlly BLOW out because of primer pocket Over Expansion in size ! - The metal case is supposed to stop that expansion like it does with the 7 BC cartridge . I will assume they will be using the same primer in the Super 65 CreedMore !

What about blanking a primer?

I did this, hence why my bolt thrust isn't as good........

Shooting blanks isn't what it's cracked up to be..........

See post #81!.......

Can't believe that guys pop a chubby for a 155 grain bullets at 2750fps.



That's the country the 303 British lives in.


But, but, but muh Ballistic Co-efficient.

Bigger calibers always shoot faster.
A .303 with peak technology will shoot 300fps faster as well, assuming the action can handle it.

The debate is old as time immemorial

I'm so glad random people on the internet are way smarter at cartridges than an entire company that makes cartridges.

What would we do without CGN telling everyone they are stupid?

Like I said I'm just excited to see how this all goes and am happy companies are still pushing R&D

The 270 Winchester smokes this "new technology".
