Riceman -- If you bought the RCBS Master Reloading Kit, you have the Speer #13 manual and it is excellent.
For the 44 mag, Hodgdon's H110 is THE powder for full power loads with all bullet weights (jacketed). The Speer manual's loads uses the CCI 350 primer with ball powders, but I personally prefer Federal's 155 primers for all loads in cartridges that use a LP primer. I also mostly load the Hornady 240 gr. HP/XTP and the most accurate load in my M629 is 23.8 grs. H110 for right around 1300 fps. (Starline cases, 240 gr. HP/XTP, Federal 155 primer. Bullet is seated to about the middle of the cannelue and tightly crimped. Sorry, but I have no pressure data.)
For general target shooting with the 44 magnum, get some 44 Special cases, some 240 gr. LSWC bullet, and some Alliant 2400. Start working up from around 11 grains. (My M629 give best accuracy with 12.6 grains, and yes that is more than is shown in the Speer manual.)
For the 45 ACP, get some 200 gr. LSWCs, Blue Dot and/or Unique. With Blue Dot start at around 9 grains and work up in 1/2 grain increments. All five of my 1911s achieve best accuracy with 10.5 grs. Blue Dot in Starline cases, Federal 155 primers, 200 gr. LSWC. Out of the 5" barrels of my full-size 1911s, this load produces 974 fps and produces about 18,500 psi in my pressure-test barrel. If using Unique, start at around 5.4 grs. and work up in 0.2 gr. increments. My accuracy load is 6.2 grs. for around 850 fps (5" barrels) and around 15,000 psi (test barrel).
Can't help any with the 9mm.
