I guess let me be the guinea pig.
I only have the 75s because they were on the 73 spot on the shelf at cabelas. Realized they weren't 5.56 mag length so I might as well try them in valk.
From what I am seeing 2900-3000fps should be doable. They still have a .46ish bc doing 1200 something FPS at 1000.
