150 grains of loose powder is really just a waste and doesnt burn it all
You are right though about large loose powder charges being a waste. In a 26" barrel, 110 gr. of loose is about the maxthat'll efficiently burn. In the longer 28-29" barrels some of the newer muzzleloaders are sporting, one could probably up that to 120 gr. loose.When they talk about 150grain charges, they arereferring to pellet form, not loose. Something about the pellet design produces an more efficient burn, Ibelieve.
