[QUOTE="daveosok, post: 104370"] You must first take into consideration the type and caliber they were shooting and what the subject matter covered. That length proved to be optimum barrel length for there particular circumstances. Dont take the 21 inches to mean that a 300 win mag shooting 200 grain pills will best be suited in a 21 inch barrel. The length of the barrel they choose will not meet the criteria for such cases as the 300 win mag, 7mm stw, Rem ultra series, Allen Mag series or any case capacity greater than say 70 grains of water. All of the above mentioned cases will need a lot more than 21 inches for opitmum barrel length versus case capacity. In a conversation with Dan Lilja I had a few years back he stated that for a 95% or better powder burn in a cartridge that had 70 or more grains of powder needed 34 inhces of barrel length. This was covering heavy bullets such as Berger's 180 grain VLD and now 175 SMK. [/QUOTE]
