i am in the same boat. i been researching load data for the 35 rem. i have call several of the powder makers and talked with them on a reduced cast lead loads. i got several starting points but not the time to load and chronograph them. i am going to get a good 35 rem cast lead load for nra cowboy silhouette matches that will work out to 200 meters. i am going to be working up some cast lead loads in february when i finish the 357 mag cowboy silhouette loads and the rechecking of my 44 mags cowboy silhouette loads. if you are going to do hunting loads any book data loads will work. i am going to use a .38 cal bullet around the 158 gr size pus with either sr4756, unigue, bullseye, mp5744, and/or titegroup. brass is hard to find. i had a guy in concho az make me 200 rounds of brass from 308 brass. he makes a good product. you can find factory ammo if you use one of the ammo search sites.
