Use Tightgroup, good for all but the heaviest loads in those calibers. The powder costs are actually trivial compared to the cost of bullets, even lead bullets. (The following figures are not necessarily for you but others that might read this thread)
Say 2 lb of Tightgroup = $38 (from Higginson)
Average load for all your calibers = 4.0gr (not max loads)
Total number of loads = 3,500
Cost per round = 1.1 cents.
A plated lead bullet will cost you 8 to 12 cents per round
Primer about 2.5 cents per round.
