 Most ammunition manufactured for the cartridge is loaded with a bullet at which has become the industry standard for the cartridge.There has been some criticism of the cartridge for its inability to reach the so-called magical velocity (with some powders) some hunters, especially those who hunt large animals, believe is required for maximum penetration on dangerous game, the end result is that no scientific proof has been made on this subject, and it is likely accepted because of the older bullets that will not retain their weight at high velocity.This is a particular concern outside North America where only particular lines of cartridge powders are available, sometimes of local manufacture.
