45.1 netted a best 2 of .5" and .75" for a composite of 1.3".
168 TMKs also turned in some good groups with 4064 with the best 2 at .45" and .5" for a composite group of 1.0"
All cycled well with no obvious pressure signs.
I shot all of the test loads at 3 different seating depths. And not a single one shot well at the deepest seating so I removed that one group from each test.
One variable we don't mess with is seating depth. Mark loads to max mag fed length and we roll with that. I know its a thing, just not a thing for us. And has never been an issue getting sub Moa performance. Same for Bolt guns.
