The 2600 FPS claime that Barrett makes in refference to his 25mm x 76mm round out of a 17.5" barrel doesn't seem possible. The round is more like a grenade round then a rifle round and compound that with the fact the barrel is a mere 17.5". 1600fps would be more realistic given the rifles attributes wouldn't it?

Physics wizards help me to understand this round if you wouldn't mind.

What's the projectile mass?

Regardless of the ballistic performance claims, I know many operators who have seen (as I have) this weapon test-fired, and have refused to shoot it. Unless this thing is vehicle mounted, the dismounted applications are limited. The recoil is just not manageable.

Since I am shopping 25mm guns, this is a timely thread.

The round is not a grenade round like the 40mm for the M203. It is a cannon round for the Bushmaster Chaingun on the Bradley IFV. Higher pressure and velocity than the grenade rounds.

As for the claims, I have no Idea, but the effective range on the bradley's gun is somewhere near a mile and a half IIRC.

I know the 25mm bullet itself is from a Bradley Vehicle round but the case is Barret proprietary and much much shorter.

Is it really that severe?? I figured with Barrett's newly designed high efficancy 3 chamber arrow brake it would be rather managable....

After we saw that thing fire at a demo we all sort of looked at each other and said, "You first!"

From my perspective, the weapon has one role, anti-vehicle. In that role, I think it could be a good fit on an RSOV or other type vehicle.

For anti-pax there are better options, like the .338 and .50. I can't see the utility of a weapon with a perceived max-range in excess of my ability to ID the target through my optics. Even at 32x, I can't positively ID a target at 2K+ meters.
