Pistolchamp,
Don't worry so much about getting Wrights book, you NEED to get a copy of Ross Seyfrieds article, if you need, I can mail you a copy. With all due respect, (a great deal by the way), to Marrakai I wouldn't use a bullet heavier than 440 gr in this rifle, they were set up for 340-380 gr bullets. If you do get Wrights book please be very carefull about using the duplex loads he mentions, they can very easily get out of hand, and to be honest, they spook me. KIK 2F will give you all the horsepower you need in a straight black powder. You'll find it far easier to get a regulating load with 4198 as Ross recommnds than with black and at lower pressures. Remember, you are but a temporary custodian of this rifle, I know you really want to hear it go bang asap but please slow down and do it right.
As for the new packaging I'm with Marrakai 100%, somebodies going to blow up a rifle when they drop a NE load in a rifle thinking it's a NFB cause they didn't read the label.
