I bought the 220 a couple of weeks ago. Instead of accutips which I used in my BPS 12 gauge for years, I tried 3 inch federal premium trophy copper tipped sabot slug in the 220 with great success. The Savage manual recommends 3 inch accutips. I'll stick with the feds. at $20.00 a box. Next year I'll try 2-3/4 inch. If they are as accurate as the 3 inch, even better at $15.00 a box. At that price, I won't mind banging off a few boxes at a shooting session.
