Bloke that gave me the loading data for Tr140 told me i could not use it with the 45/70. But
If look in the Hodgdon basic reloading book on page 13. N140 and Varget are next to each
other in there Burn rate. In my Lee book that came with the 45/70 dies you can use 40gr
Varget with 405gr lead bullet. and thats a start load.
