I weighed the cartridges and believe the 180's to be 165gr.

1500 fps from a 180 grain would be very difficult has to be incorrectly marked...you may want to peak inside before blasting away with them...

Their site says 165 and the weight I get concurs.

Might have switched the fps for the 180 amd 125 grains?

Bingo. Good thought..

They don't have any videos for the Halo round or pictures of the internals.

After looking over their website, I see these are 100% copper projectiles and they will be lighter than the lead counterpart so they will be long for weight like Barnes and others.  They also appear to have power bands where the entire projectile is not contacting the rifling, this will reduce frictional surface contact which can translate to speed increases, however accuracy might suffer...

Also the line on the HALO is there by design and not a crush line marking from the seater plug during seating as I first thought.

Still waiting on the 125gr response, but think they are 1500 FPS. The other one is 165gr @ 1200 FPS.
