Specifics on the weapon like caliber, capacity, frame type, weight, and barrel length as well as
cartridge information such as weight, velocity and composite and style of the bullet give meaning
to references such as amount of recoil and accuracy (must have the distance from the target).
Other specs such as penetration and amount of expansion or deformation of the round are also
useless without the above information.
If it is a new model firearm or cartridge type the use of examples referencing more well known models
in similar size, weight, or platform helps with forming an opinion that may spark an interest in the reader.
Being informed they are more likely to try or not try it themselves rather than simply being ambivalent.
Just keep oranges with oranges or if need be, tangerines.
Any problems and their solutions (if found) should be noted. Be as specific as possible with these.
Finally, cost and availability of the firearm and or ammo as well as reloading specs should be noted
if available.
Just keep things in terms that people can identify with.
