I use to use a Mossberg 12 Ga. Tropy Slugster with cantilever barrel, now use a 11/87 SP 12 Ga.with cantilever barrel have a Leupold VXIII 3.5x10 and it works great. I did have trigger reworked on it and I use Rem. Core-Lokt Ultra Slugs. I did just get my grandson a H&R 20 Ga. Ultra Slug youth model for Christmas, Sure hope it works fine in 2009.
