Quote" heat is their (MMP) enemy warm barrels working on the sabot seem to reduce their accuracy where the Harvester seems to handle a bit more heat before a reduction in accuracy may occur.

Due to the fact that I live in AR only during late hunting season is it actually cool, most of my shooting is done in 80 and above degrees.
There is no dought that here the Short Black Harvester is best especally with pointy bullets though the occasions it works with the large hollow point bullets are rare. At least part of it may well be due to the tempaturebut I am coming to believe that the shape of the point and the sharpness of the angle and hiegth of the shoulder is having an effect. Sometimes the differance is apparent and some time it is only a 1/4 or 3/8 of an inch.I will see if I can find an example in my targets.
