I own a Savage 210f, (bolt action, rifled 12ga shotgun). It shoots 1 in groups at 100yds with Remington core-lokt ultra's.
Now I'm taking it to the next step with a Savage 10ml w/accutriger. Normally these are great guns out of the box, however I couldn't resist going a bit further. I just order a new Henry Ball custom 10ml lmtd. Fortunately I order mine days before they stopped producing them, for the time being.
I'll let everyone know how it is when it arrives in about a month...
