Sometimes I've put together loads based on what components I can get. My latest loads are in FC brass, which I usually prefer not to use because of its lower case capacity compared to WW or RP brass. FC commercial brass weighs the same as Lake City military brass. So, here's a couple loads I "threw together with what I have" using FC brass that shot great-
150 gr Ballistic tip, 45.0 gr IMR 4895, WLR primer
165 gr Accubond, 44.0 gr RL15, Fed GM210 primer

I have not chronoed these, but they shot well in several different rifles.
