But I noticed he is not checking his charges (powder check die).
I suspect he is using a powder suited to mass quantity loading, either a short stick or ball powder. Since he is basically loading blasting ammo (ie short range or under 100 yards) there is no need to check the powder since it likely all drops + or - .2 gr or so.. and so long as it runs his particular firearms, why bother?
I load for 223, 30-30, and soon 308 win and use a similar method to Randall and I never do a powder check. I usually use exclusively ball powder for 223 and 308 and in the case of 30-30 I use trailboss which meters just fine through my Dillon measure. 8.5 gr of it fills the 30-30 case about 70%.
