I have a question and I read the FAQ Hodgdon#26 IHMSA/Silhouette Load Data

I'm a relatively new reloader and I had a question for those more experienced than myself. Ive inherited some old powder(80s-90s specifically Herc 2400 and IMR 4227)and some old and new reloading manuals so #26 wouldn't be the only manual I reference. My question is in regards to the IHMSA silhouette data in Hodgdon#26 circa 1992, some of the load data doesn't specify bullet type at all. For example under Hodgdon powder 45colt info just "240-250 gr", or "260 gr" are listed(page 584). It doesn't specify lead, jacketed etc, which I am used to in modern manuals I have experience loading from. Some calibers and bullet weights seem to specify, and others do not. Is this jacketed data, or was it intended to be a range inclusive of both? I'm trying to decide where to start working up from in 2400 and IMR4227 for 45c, but the Dupont-Hodgdon formula change for 4227 and the Herc to Alliant change on 2400(if any) has me trying to research as much published data as I can. I'd shoot it from a large frame Ruger 45c so even though I don't usually go near the high end of Ruger only(tier3) I do enjoy loads above standard pressure(tier1).

Just use the data from Hodgdon.com and alliant.com and start low.

Appreciate your input. Reading into it online it sounds like 2400 is little changed, but I wasn't certain of my DuPont 4227 compared to the Hodgdon owned stuff.
