Specific load types are designed for each unique powder actuated tool. Powers
tools use cased powder loads in which the propellant is housed in a metal case.
They are offered as single units for single shot tools and collated in groups of 10
into plastic strips or metal discs for semi-automatic tools. Powers tools use .22
caliber "A", .25 caliber, and .27 caliber crimped, rim fire powder loads having
power levels ranging from 1 - 6. Powder loads for other commercially available
tools are also available such as .22 caliber Ladd and .27 caliber long.
The power level of Powers powder loads is marked on each box of loads. As the
number increases, the power level also increases. Power level is also indicated by
the color of the box, label, and the color on each individual powder load.
