Umarex Notos...my notos can't group heavier slugs

Yes sir, they do. I'm not a fan, too much force on that little pin in plastic.

Did you notice a velocity difference between the V1 single hole TP breech for the FX kit and the V2 (3 holes in a recessed channel)

I'm getting significantly lower velocity with V2. But, much better accuracy
