Default RE: How much black powder in a 30/30 load?

The 32-40 rifles were prone to blackpowder fouling and needed to be cleaned after every shot to give target grade accuracy.Fouling was so bad that they developed a duplex load with a few grains of smokeless placed in the case first followed by BP that in effect significantly reduced barrel fouling and eliminated the need to clean between shots.The 30-30 was originally loaded with IMR 171/2 smokeless powder which was replaced with todays IMR 3031.Point being a worn .32 Special 1-16 twist will give patterns instead of groups while a worn 30-30 with it's 1-12 twist will still shoot.Nothing personal against the .32 crowd it's fact.
