Here's some "QUICK" notes I made from info I found on the net and I had them saved on my PC. I've tried some, not most and I make no claims as to their safety. Some notes are short and almost un-understandable others are self explanatory. USE INFO AT OWN RISK!
18-20grs SR4759
110gr Carbine bullets using 4198 and 4895 @ around 2000fps
10grs Unique and 100-110gr jackets bullets

125/130gr Jacketed with 8-8.5grs of Unique for 1500fps
13grs Bluedot behind a 150gr bullet (not sure if this is jacketed)
IMR SR4759 powder may be the best.
15grs SR4759 behind a 100 gr JFP 1834fps from 24" barrel
17grs SR4759 behind a 150gr JFP 1794fps from a 24" barrel
13 grs of Blue Dot will work in about any .30cal
10grs of Unique will work in any .30cal with 100gr speer plinker at around 1475
12grs of Unique in 30/30 with 100gr speer at around 1625fps
100gr bullet w/ 15grs sr4759 = 1834fps in 24" barrel (Chuck Hawks)
100gr bullet w/ 18grs sr4759 = 2034fps in 24" barrel (Chuck Hawks)
