Hornady 450 Bushmaster MZ out of 16"

[atepointer]

Any of you guy shooting Hornady 450 Bushmaster 250g factory ammo? My buddy just picked up a Ruger Ranch 16" and all the Hornady box loads show 20" barrel just not sure how much to take off for 4" on that round....thanks if ya got it as we don't have a chrono.

Mine is a 16" gas gun but I avg 2100 out of it with the Hornady black ammo
