In another sense, it means 'maximum capable powder load.'
The first smokeless powder loads were intended to match the standard velocity of the original black powder rounds.
To this end, master gunners first simply used larger powder loads.
Increased powder loads in combination with increased bullet weight may create dangerous pressure conditions.
This allows for either increased powder capacity, heavier (and therefore longer) bullets without compromising the powder load, or a combination of both.
It used a different powder load, and ultimately the case was extended by 1/8 of an inch (0.125 in, 3.18 mm).
The cartridge is comparable in size to the .50 Action Express, but has higher powder loads and normally a lower velocity.
Slightly muted, as if- "They're using light powder loads," said Gregory.
The smaller powder load also contributes to longer barrel life, an important factor for high-volume shooters.
Military specifications called for black powder loads, replaced by a mild smokeless powder in the early twentieth century.
