I load my rifles with a powder that gives at least 90% case fill, but I prefer compressed and more like 110% fill.
Again, barrel length has nothing to do with burn rates, velocity yes, burn rates and complete combustion, no.
Steve i beg to differ. when you get that huge muzzle flash out of the barrel when shooting shorter barreled firearms, that combustion.
my 25-06 when shooting a reload with a 120 gr bullet has little muzzle blast. when i shoot a hot reload with 75 gr bullets it has a huge muzzle blast that can be seen in the scope.
this was alos a problem with the 220 in earlier years, and caused them to have a reputation as barrel burners, because they didn't complete the combustion in the cartridge, but did in the barrel.
