Yes, I have read and reread Dan Lilja article on 338 Barrel length, and have scoured every thread I can find on LRH, and feel confident the difference in FPS is negligible. Then, after measuring, and remeasuring, and remeasuring, etc. my drag bag (and commonly available hard gun cases), various total length(s) of barrel plus muzzle brake
, and then rifle overall length(s), I have decided that 28" plus brake (for a 30" barrel OAL), and therefore a rifle OAL of 50.5" is the direction I will be going.
Thanks for everyones input.
