I just picked up an Accura PR and ordered the BH breech plug myself. Knowing the differences seen with my TC breech plugs, the dished out breech plug for loose may cause the bullet to be seated just a tad more than the flat face breech plug. Whether that would cause enough difference to change POI, can't say for sure. One sure way to tell if you have time, simply load one up with the new breech plug and put one down range.
