9T 223 should be fine with the 75 A max......
Tweak load.....change primer....seating depth
Burning Varget ?
It's a toss up with the 1-9" twist. My other 1-9" loves them (so I have a bunch) but this one doesn't look like it'll go.
How would tweaking the load, primer change and seating depth affect bullet stabilization?
