Barrel length question?

[texas bound]

Do you add the length of you can to your overall barrel length when looking up reloading data or do you just use the barrel length? I am using quickload software.

No. Only the rifled portion of your barrel. Also keep in mind a suppressor will slightly increase pressure so take that into account and do load work with the can on.

Just barrel length in my experience.

Ok thanks. My can should be in next month and was building some loads on quickload tonight.
