While a 16 wingmaster is sweet, it ain't no SWEET SIXTEEN. Have to get a Browning Belgium for that. Someone commented about the wingmaster being a sweet 16 so I had to say it. I shoot a SWEET SIXTEEN and love it. Noble makes a shell in 4's and 6's for $8.00 a box that works great. Are you certain about a pump gun for Upland. That is the way I started but not what I pick up to go afield these days. The 16 may swing a little faster than the 12. That would be my reason for choosing one.
