Yeah ive heard people get concerned about not getting 100% burn in a short barrel when using a suppressor etc. In my experience i wouldnt get too concerned about it, i run a 15" 7mm08 and a 17" 284w both suppressed, ive just used the powders that give best velocity while retaining good accuracy and havent bothers about % burn in the barrel (figures from Quickload) and it doesnt seem to cause any issues in the suppressor.
Some times we tend to worry too much about things that are not really an issue in reality.
