Velocity in a 450BM bolt gun from a 16 vs a 20" bbl

New to the site tonight and I have yet to figure out the search feature on this site. I am sure this has been discussed at great length somewhere on the site but I cannot locate it. I am in the process in putting together a southern Michigan whitetail rifle for next year as well as one to be be used in close quarters blinds in heavy cover in Northern MI. I settled on a 17.5" barrel with a varmint contour on a Savage single shot action with the factory pillar bedded stock. I have several of these guns in different calibers and they all shoot like a house afire if I do my part. Does anyone here have first hand experience with the same load out of two length barrels and was there any appreciable velocity drop? I have read conflicting information about the 450BM with regard to powder burn. Some state that there is compete burn in a 16" barrel while others claim almost a 10% increase when stepping up to a 20" tube. Who is right?
