This is 3rd hand but a friend of a friend is saying that he is getting 3100fps out of his 300WM using 208gr Amax bullets. Said that he confirmed it on two different chronos because he didnt believe it at first. Thats about the velocity I'm getting with 185gr Accubonds. I looked for some 4000 at Cabelas the other day but they didnt have it.
Ive tried it and honestly those numbers sound about right for what I'm getting out of my 300 WM AI. I only used one chrono and assumed it was wrong. I found it at sportsman's warehouse.
Couldn't find any data on the Alliant site for something similar to what I shoot, so I'm waiting on QL data. I've had very good results with the 2000 MR, looking forward to trying this.

I ran into the same issues and I have even called alliant and they haven't done any load testing for 220, 200 smks or berger 210's or 230's so I'm honestly resorting to trial. Loading it similar to RE 22 and running with it.

Nope, right next to RE22.
