From the previous post, it seems like the ADI powders will do 1300 fps from a rifle just fine. Exact charge is hard to predict.
Here is a list of predictions for similar powders from a 16" gun. Note that all predicted pressures are well below max.
Code:
Cartridge : .44 Rem. Mag. (SAAMI)
Bullet : .430, 180, Hornady HP/XTP 44050
Useable Case Capaci: 29.151 grain H2O = 1.893 cm³
Cartridge O.A.L. L6: 1.590 inch = 40.39 mm
Barrel Length : 16.0 inch = 406.4 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Muzzle Velocity: 1300 fps or 396 m/s
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
