What follows and $1.85 will get you a "Tall" Starbucks coffee:
Modeling with QuickLoad and that is by no means an accurate analog to real results, the following charges are alleged to deliver the following performance. YMWIALV (...will in all likelihood...).

That doesn't mean to order some of these bullets and load those charges right out of the chute.
In theory (see sig), they are near or slightly above the QuickLoad maximum recommended pressure based upon a solid copper bullet, so naturally you would
start lower and work up. Some of these powders I have never worked with, but I can tell you from my experience that W296 models a lot higher with lighter bullets, than it really delivers in the 450b. The percentage burned should be a giveaway.
I like loads that use up most of the case capacity and my best luck has come from those which burn about 95% by the time the bullet exits the barrel. You'd think 100% would be best, but that has not been my experience. You want to
leave a little for the cleaning lady.
Again: This table is based upon a synthetic algorithm, not real world experience. It is solely for the sake of giving you an idea of what may work in terms of powder choices and even then they may wind up not being a good match. With such a light bullet, you really have to hold the horse back until the powder gets going, so crimp is especially important. Sort your brass by length for best consistency when using a taper crimp and light bullets. BTW, Yes, I do have Vihtavuori N110. The bottle I have exhibits slightly less energy density than Lil Gun and a lot of granular debris downrange that looks like cream of wheat. Never figured out what it was.
