sorry, my BSmeter went off too loudly for me to watch that
Emeric, I am not a ballistician, but what do you estimate would be the chamber pressure of a 6-7 gram 6.5 mm bullet fired from a 6.5x49 mm Creedmoor cartridge at 3,000 fps / 914 mps?
The 264 INT (the child of the 264 USA) is pushing a 6.7 g EPR bullet at 3010 fps out of a 20" barrel (and 2850 fps from a 14.5"), while staying below 62 kpsi.
How interesting. I was not aware of this cartridge. Can you point me towards more technical information about it.
I am going to contact you separately to discuss NGSW!!!
Great picture! I’d also like to know more about the .264 INT, and how it compares to 6.5C.
Disassembly of SIG Spear.
Note, the "PDQ" that is mentioned a couple of times is the aftermarket "PDQ ambidextroud-bolt release" that Karl has used in the WWSD (What Would Stoner Do) carbine.
The PDQ is such a lazy implementation of ambi.
LWRCi and LMT have a much better, true ambi lever that is both bolt catch and release, and have for the last 6+ years.

Guardsman26 said: My understanding is that SOCOM units deploying with 6.5 and 6 mm weapons have an EPR loading.
Very interesting. A pity we can't get a photo of either EPR bullet.
It looks like we got a photo of the 6.5mm EPR. https://forums.delphiforums.com/autogun/messages?msg=7519.2783
