Which powder will give the most FPS per Dollar from a 20" barrel?

Really need more info, . . . but . . . Study manuals, compare info, choose best 3 or four powders, and start with one with lowest pressure at high velocity. Start with Regular primer, then with best load drop a notch or two and try Mag primers. The winner will make itself known pretty quickly.
 
Whatever's inside the cup of a primer. Guarantee if you scrape out the contents of enough of primers to completely fill a .30-378 case to create a compressed load of primer dust the bullet will be going REEEEEAAAAALLLLLY fastā€¦as will the chunks of your exploding rifle and head šŸ¤£

My Canada brain saw an impossible to sensibly answer question and decided to go full maple flavoured beer drinking lumberjack hockey playing polite apologetic frozen beaver on it!

IF you're staying inside safe pressures the powder best for a 20 inch 243 will be different than a 12 gauge or a muzzleloader or a .22 hornet or a 375 cheytac (and there's a guy on here somewhere has a .338-375 ct "pistol"). No way to answer the question.

But if it's purely literal and safety and pressure ceilings be damned it's gonna be some kind of flash powder no matter the case. The rifle and it's operator likely don't survive. But it's the most energetic powder.

Saskatchewan and Alberta do increasingly feel like their own thing in some ways.

The ideals of respecting individual autonomy, minding one's own business, working hard to earn a living, acknowledging agriculture as a the backbone of all modern civilization and paying due respect to those who feed us, and letting people provide for themselves and carve out their own path in this world are all very much things that Ottawa (and Quebec) don't respect.

Edit: I see you're from Alberta! You ain't getting out of this! šŸ¤£šŸ¤£šŸ¤£šŸ¤£šŸ¤£
