When I get hold of a new bullet, I make a dummy round -- it basically has to feed, I always end up with my rounds too long and then it catches under the barrel and you have to force the lever down to get the round lifted. So make a dummy and make sure it feeds with a little space to spare for "manufacturing tolerance"
Lots of crimp, for consistency and to hold the bullet in the magazine. Trim your brass for a consistent crimp... but you probably knew that.
Sounds like you're spot on where you need to be. Depending on your rifle you might be able to push that load another grain or two, but depending on your rifle that might also be dangerous... this is pussyfooting through Chrony territory IMO.
So, what's it shoot like?
