I think it is like anything else in this world we live in - what works for some does not always work for others.
I have shot a good deal of BH for testing purposes and have not found an accuracy issue... or even a significant velocity gain or loss when changing from T7 to BH in a grain for grain swap.
Running a patch at the range is not a problem for me at all and one patch works up to 20 shots for me.
Do not get me wrong either, I really like BH and what it does... everything but the cost per ounce... even if the two jugs were approxiimately the same price you are still losing a lot of shots with BH.
That breech is really clean... What primer do you normally shoot in the X7???
