The difference in velocity between 16 and 20" barrels is about 100 fps. Most people run optics now, so sight radius is not an issue either.Sean D Sorrentinohttps://www.blogger.com/profile/02710448105506060349noreply@blogger.comtag:blogger.com,1999:blog-4146148016062694502.post-28733664484743329592011-05-05T09:28:18.848-04:002011-05-05T09:28:18.848-04:00My 20" is a lot more accurate over 200 yards ...My 20" is a lot more accurate over 200 yards than my 16" is.

I don't have a handy link to the most specific paper by him on this but the links at the bottom of his <a href="http://en.wikipedia.org/wiki/Martin_Fackler" rel="nofollow">Wikipedia entry</a> should get you to it if you're interested.ThatWouldBeTellinghttps://www.blogger.com/profile/16910231314995266781noreply@blogger.com
