Nice video, thanks. Impressive showing by the 16”, comparatively. The 20” will still be giving greater velocity though. Maybe that will show with at the 600 yard range. Either way it would be slightly better terminal ballistics.
@Novum-su9ie When I first got them I would have said the 20" was slightly more reliable, but after putting in the updated gas block and putting silencer on them they both run flawlessly.
