Halo ammo weights?

And yesterday I had coffee with the Tooth Fairy, Santa, and the Easter Bunny 😂

I was going to join you for coffee yesterday!

But Big Foot almost stepped on me, and Loch Ness wanted to swallow my hide.
Not even with my .25cal P-3 shooting ATP slugs at 85FPE did I make a dent into its plated armor.

I barely survived.
Dr. House stitched me up.

All i know is the .177 come dead last,,,,,, and that's even a big maybe in my mind.
There is a chance but only as FX is a Swedish brand.
I think FX farmed out the .177 Halo to JSB..in the form of the JSB Knockout MK3..10gr. The MK3 really looks pretty “haloish” to me. 😉
