I don't shoot that much VFS, but whenever I make Black Creek, there are a few guys using the old Louie, frozen, with adjustable bases. Also a smattering of Weavers, more new Leupolds & Nightforce (BR models) and the occasional Sightron 36.
Other possibilities: The new Sightron *looks* good, but no track record I know of. Rich DeSimone shoot a Valdada in 1,000 yard BR and it seemed to hold up.
I agree it is nice to get sighted in in the morning, then hold off the rest of the day -- or yardage. My scopes, group or score, seem to take 4-5 shots to completely settle down after an adjustment. The groups aren't much bigger after a knob fiddle, but more often than not, a little bigger.
Had an interesting experience this year. I shot an indoor 100 yard VFS match, and had a real no-wind zero. Then went to Black Creek. The "no wind" there was l little different. I couldn't help it -- adjusted for that during the warm-up match. Much more comfortable on the brain when you start with a days/ranges "zero." Maybe your brain is younger & more agile, but 1/8 minute clicks are a comfort. And yes, the "frozen" guys claim they get as good a zero.
FWIW
