I pretty much use strictly brass measures.
For my .45 flinter (shhhhh, don't tell anyone I have a small bore, it ruins the illusion) I use a Treso 0-120 grain with the swivel tip.
For guns from .62 - .72 I have a Treso adjustable measure from 40-200 grains.
For the 8 bore I have the Treso adjustable measure from 150 - 300 grains.
When I was shooting 4 bores, I used the 150-300 grain measure. For charges over 300 grains, I would set the measure at say 200 grains and fill twice for a 400 grain charge.
I have used fixed brass measures, but do not care for them as well as the adjustable.
For hunting, I have made up some loaders out of PVC pipe and fittings. Looks kinda hokey, but works well. Line up the speed loader with the muzzle, fit the short starter in place and give it a rap, and the powder is in the bore and the PRB is seated down the muzzle. Just that fast. A piece of wax paper holds the powder in place and breaks open quite easily when the starter is struck.
