You almost need a magnifying glass to see the difference between the 220gr. 30-06 hawk load at 2450fps. Also the use of magnum primers seems to never be even attempted to explain. Their hotter longer, hotter burning flame is used to ignite ball powders where there is less air space, and not necessarily slower burning powders as H-1000 works with even the coolest as it is less heavilly coated as the older powder like 3031 had to be before they figured out with 4320 that the short cut idea worked. |
