You'll have to do like the rest of us, pick a powder that gives the velocity you need and see if it shoots in your rifle. What shoots <.75" in my rifle may not shoot worth a hoot in yours or it may be the opposite way. That is the reason if you were to look in most reloader's powder storage bin, you'd find a mix of different powders, a many left over from trial loads that did not work, but may work well in another gun/load. Once you find "that load" then it time to buy in bulk. If there were "one magic load" then all the other powder/bullet companies could close their doors as there would be no desire for their products.
From what I have read, TAC is one of the best as far as cost/accuracy ratio, I don't know because I never shot any of it.
Reloder 10X & 55 gr bullets is working good for me right now. I may find something better as the supply gets better.
The cost of the bullet and primer(mag may cost more) are same in a load, so you have the powder cost. Take the Reloder 10X load for example: 7000 grains / pd.... 7000 divided by 23.5 grains per load = 300 rounds/ pd. At $26/pd ... 300 Rds will cost $.0866/load for the powder. Find the powder that will give you the Accuracy you need, the cost you need and you're set to go.
But then you have a shortage like the last 1.5 years and you have to shoot what you can find. You learn to make do with what ever you can find.
