drop tube use

[Lumpy Grits]

I reload out of necessity-Plus my OCD helps here.
My SWAG on the drop tube use before compression, the powder granules are more consistently 'stacked' before compression.
A few years back, I did a test in my .45-90 with 30 rounds loaded the same except 15 were drop tubed, and 15 were slow poured via funnel before compression.
The drop tubed load was 'tighter'(smaller)and far more round than the funnel loads were. This was shot at 300 yds...
Yes-I'll keep using the drop tube.
YMMV,
