[QUOTE=Harter;29824]The Lyman 48-50th Editions have lots of Trapdoor compatible data for the 45-??s in smokeless .

This is from my experience. Double check all Lyman loads for 45-70 TD and 45-90 against powder makers data for AAC 5744. In older editions I have run into TD and 45-90 there that were too heavy based on powder makers data. Data changed in following Lyman editions.
