Powder for 44-77

[Nuclearcricket]

Gentlemen, I took my roller and barrel to the smith today to get chambered up in 44-77. and now I need just a touch of advice. I am looking for suggestions on what powder I should use to fire form my cases. As it stands right now I have about a half a case of '98 vintage Goes CTG, 2 cans of 2F Swiss, and 2 cans of 1.5 Swiss. I did load up 10 rounds for the smith to have to do the test fire. For that I used 74 gr of CTG compressed about .130 or so, a card wad and a coffee filter primer wad. I do admit I was in a bit of a hurry and forgot to put wax paper under the bullet but for those 10 rounds I don't think it will make any difference. Its just important that it goes bang and that big lead slug goes down range.
