I did the math on BH 209 vs. T7 a few times.
I came up with it adding $5 or so to a trip to the range. When you consider all that goes into a trip, time, gas, cleaning, projectiles, etc., the extra cost of BH doesn't seem like a big deal to me. I do shoot all powders and have yet to try BH with conicals.
