The footage with the M240 has me hopeful this could make it to the civilian market.
I also like that the requirements have the suppressor included.
This is the first one that I have seen where they actually designed a case to be made from plastic rather than trying to make a 308 or 223 case out of plastic. If they can get the case head integrity down, which it looks like they have, and can design an extractor and rim that can extract in extreme conditions then I think they will have it licked.
and tackled that problem by eliminating the neck.
I didn’t watch the entire video, did they show a cut away of the plastic case or just a projectile?
Neck tension was another issue with the stuff I had.
A recent thread where we discuss all three rifles/ammo competing for the NGSW contact.
I didn't see a cutaway, but he did mention they said polymer allowed them to alter the internal geometry of the casing in ways they can't do with brass. I got the impression it was for powder burn issues, not strength, but you never know.
He mentioned they used a brass washer between primer and case to protect the plastic. I can't think why that would be an issue unless they planned to reload.
Previous work on plastic cases for standard chambers like the AII Neckless had reduced volume such that they had to go down to a 130 gr .308 to keep the velocity and trajectory up.
Plastic cases have come a LONG way since first considered. To me, it looks like True Velocity has worked out a lot of the previous bugs.
Works to a point in some gun games.
FWIW there are accuracy standards that must be met along with reliability ones, the “spec” part of “MIL-SPEC”. At least until they decide thats not fair to things that suck and they eliminate them in the name of equity.
To be fair, my well used 1919 (floating barrel) with an optic on it is more accurate than some bolt action rifles I have come across. Part of the problem with qualitative statements like “less accurate”, what does that mean in inches of difference at 600 meters?
I fully understand that some rifles with barrels that move can be accurate. I understand some barrel with stationary barrels aren't that accurate. That has nothing to do with the statement that they could help remedy issues of barrel motion inaccuracy with increased velocity.
Yes, standards have to be met. They are expecting to pair this rifle and ammo with an electro optic sighting system that will allow for 600 yard shots (IIRC).
