As the title says (tried a search, nada specific); recommendations on powder/wt, C.O.L., tips etc., aiming for hotter results? Any input much appreciated! Looking for some good, solid thumping ammo for a Ruger Redhawk :) .

4 data points for 300gr jsp in that list, you could always check Hodgdons site (xtp) and try different lengths.
 
I've been using IMR4227 for my 300gr JSP loads in my Super Blackhawk. As F55 suggested, lots of others out there hodgdon reloading site is a great starting point. If you want a break from the thumper loades, you may also want to look at campro 44 mag projectiles in 240 grain. really affordable and good for practice ammo. There are some great plinking loads that use titegroup powder and switch to the other powder if you want more kick. Sometimes powder availability decides what you can use...
 
I have used 1000s of 300 grnrs in 44 RM and Super Blackhawks, I started loading them way back when the only maker was Barnes for the 444 Marlin. I have used exclusively Win 296 powder and CCI 350 mag primers in W-W cases. I actually trim all my cases to book min then load and do a heavy roll crimp into the cannelure, never worried about COAL, just used the cannelure on all the different makes of bullets. I worked up well beyond book max but they are a good guideline and you do not want to start above them. The 300 gn Barnes were the most accurate bullet I ever used in my 44s, in conjunction with Win 296 and magnum primers. She's a handful though with a full bore, fire breathing, magnum load............
Start about 20 grains and work up in 1/2 gn increments...........pistols are different than rifles so forget looking at primers......as long as your cases drop out or fall out with a light tap all is good, any harder than this and it's time to back off......

The load links I knew, I should have been more specific - but yes certainly a starting point. It's the hands on experience though that is much appreciated as it's a big help in fine tuning a patch to take, thanks for those details!
 
I know it's a pain, but I highly recommend trimming all your cases to the same length. When using 296, the manuals recommend a heavy roll crimp, and it truly is required for consistency. This is why I trim all my cases to the same length as it gives consistent crimp that way........
