5-8 GR of titegroup.
16gr of 2400 would be good but may be a bit fast for no gas check, unless the bullet is over sized
5gr of w231 should work well with that bullet weight.
I find anything over 1600fps needs a gas check but I also use a large bullet. I always try and get the biggest diameter I can use and still chamber a round.
Ideally you want a bullet that is minimum 0.002" over sized.
A Bore sized or smaller bullet is the leading cause of leading
If you were into powder coating it would open up a lot of options, if you ran 1800fps or faster you can use bigger charges of slower powders
