I have both, but have never loaded for the .351. My factory stash is down to one full box so I need to break down and get the stuff to load it. My first .401 was stolen 20 years ago. I replaced it several years ago but it needs some attention so I haven't done much with it. The last box of handloads I loaded shows 31 grs of 4227 with the 200gr bullet.
good info, thanks, i stopped at 29, but have not fired any, so may be able to go up in the 401
