Well, I figure that's just the price you pay if you have one specific bullet you really want to shoot. You might end up throwing the kitchen sink at it and still never find a load that makes it shoot exactly the way you want it to. I learned that lesson a long time ago, so I changed my approach. I figure every barrel has a mind of its own, so I try to let it tell me what it really wants.
Still, some people have a specific bullet they want to use. It might take a lot testing with powders and charge weight, but that's just how it goes.
Now, one load I almost always have excellent results with is a 68 grain Hornady BTHP over IMR 4895. I've built a bunch of uppers for friends and family, and that load has worked extremely well in almost all 1:7 , 1:8, and 1:9 barrels I've tried it in. Unfortunately, there's no way to get 3300 fps out of a 68 grain bullet.
