IMR..........easily the favorite.
The old brown paper from Dupont load data......it was free. I have 4 of these. They list a load from their fastest powder to the slowest for ALMOST every rifle caliber.
You still follow the rules of handloading.......but those powders do work in all those applications still to this day.........saying "its not optimum" means little to nothing....if its accurate and chronographed then go hunt or punch paper...
It looks like they decided to give you every opportunity to try whatever you have as far as their powders were concerned..........genius.
H......wants you to buy a different powder for each caliber or small change in case dimension or bullet weight........not all the time.....but.....it is very noticeable.....
Lymans cast bullet manual defeats some of that nonsense by H showing you can use those powders in other applications or cases.......when cast bullet data and jacketed data overlap......its going to work. AGAIN...use common sense and GOOD handloading technique to get safe results.
Yes, I use H's powders, BLC2.....in only 2 cartridges....223 and .308. All the other bottle neck cases get IMR......much more consistent across multiple rifles.
Best
