I know the ammunition performs differently because different patented technologies are used...I even can research which brand and round does what. I want to know about the variance of each company. When you really really need the weapon to go "bang"...which company produces the safest choice? Who is most on top of the qa/qc game? Does it vary by product type, such as with companies under LeVistas umbrella excelling at handgun round uniformity, while Remington excels with shotgun shells? Does anyone really have an area that has them on a "do not buy" list figuratively or literally?
