Think one of the problems is those hole sizes represent a miniscule number of rifles sold. The other being bullet weight goes up and powder charge realistically goes up with it. BC isn't much good with large rock trajectory so your into recoil which most seem to be trying to fix, not increase. Jm2pennies.
