Top three 20ga. slug guns under $2200 in terms of accuracy and trajectory with the 20ga being a better choice over a 12:

1. Tarhunt
2. Savage 210 ~ H&R Ultra Deluxe

Nothing wrong with Rem., Browning or Mossberg. All will kill deer just as well but if you want centerfire accuracy out to 125-150yrds, you made the correct choice. I'll take out my ML if I know my shots will always be beyond 125yrds.
