If that was Connie at MMP she is great. N110 is also another good choice for reduced loads. Its very temp stable and much cleaner than 5744. SR4759 might work too but lighter book loads are already producing rather low peak pressures. Since you have a bunch i would try it for sure. 36gr of SR4759 and a good tight sabot like the MMP short black. Probably a good idea to use a mag primer but ive had great luck using just Win209s.

Alliant 2400 was actually used early on. Around 32-34gr was max with a 250gr. Never tried it myself.
