I'm wanting to load for a savage rifle build in 35 whelen. I just put the apache gun works barrel on and fired some 180 grain hot cores and 220gr hot cores. The powder in question is Alliant pro power varmint. The 180s produced 3100fps and the 220s were 2825fps. I'm wanting to load some 200gr nosler Accubond. I'm using speer load data. They are the only one I can find with data on this powder. The listed 220 charge weight max is 63.8 and the 180 is 70gr max. Correct me if I'm wrong but it seems like I could safely start at 63 or 64 for the 200gr.

The velocity for the 180 and 220 are amazing to me so I really want to come up with a 200gr load with this powder. Speer doesn't offer a 200gr bullet in .358 Thanks
