I just purchased a 35 whelen in 700 CDL, 5 pounds of RL-15, and a bunch of 250 gr boolits, so I'm quite interested in this discussion. I found a link to the 2005 alliant data for 35 whelen on Steve's pages (http://stevespages.com/zip/alliant_reloading_manual.zip)
if anyone cares to look.

I suppose I'll work up as normal, but start a little lower than I might've with the older data. Once I find a sweet spot with powder weight I'll start tweaking OAL.

The same thing happened with my 300win data from Barnes 3 to 4. Barnes 4 would make me 3 grains over max with RL-22 but no pressure signs are evident.
