Yikes! a 16ga model 11? You better let me take that off your hands, nothing but trouble there...please, I know we don't know each other but let me do you a favor.

O.K. honestly, can't help much but you maybe look at
www.16ga.com and look into reloading. Its hard to save money on 12 and 20ga reloads unless you do ALOT of it...but it may be the answer for a 16. Try midsouthshooterssupply.com and do some number crunching on components. There are calculators out there somewhere online that let you put in component prices and spits out a per-box cost to you.
