Crowns and Muzzle Devices
There are a lot of things you can do to the end of your barrel. The primary consideration is ensuring that the muzzle is completely symmetrical, as any nicks, flat spots, or an unevenly cut muzzle will allow expanding gas behind the bullet to escape from one side of the rifling before the other, pushing the bullet off course as it exits the barrel. This is only an issue if you have a modified or damaged muzzle; a reputable manufacturer's muzzle cut does not need to be checked for consistency.
Muzzle integrity may be a non-issue with newly manufactured firearms, this is not the case with military surplus. Surplus firearms often receive rough handling as a result of wartime or training use. Many surplus muzzles have been filled with dirt and debris, ground against hard surfaces, or suffered rough treatment from hastily handled cleaning rods. Check the muzzle of your military surplus firearm carefully, and if it shows signs of rough treatment, consider shortening the barrel slightly to expose fresh and un-marred rifling. Some surplus rifles will have already received a similar treatment called counterboring, where the muzzle is drilled out to cut the rifling back to a point where the rifling grooves (lands) are still sharp, while leaving the overall barrel the same length so as not to interfere with the front sight.
Once you've ensured your muzzle is symmetrical, you can start to think about crowns and/or muzzle devices. Click on the links below for more information.
