So my huntin bud wants to start bustin yotes on my place after deer season with me. I have a Savage 22-250 that LOVES yotes and whatever else runs into its bullets!

But for him, rather than buy a new rifle he brought me an old one of his deceased father-in-laws. It's an old Savage that is a 222 on top and a 20ga on the bottom. It's a Savage 24 I think? It's drilled and tapped and I can still get a Weaver base for it and he'll put a decent scope on it. But before all of that, I'm wondering were these guns typically accurate enough to warrant all of that? I know the 222 will be a great yote/varmint caliber and the 20ga with buckshot will be great as well for when/if yotes sneak in up close and are "moving in your face".
It wont win any beauty contests but I told him I liked the general idea of that gun as he wants to use it... assuming it's accurate enough. (I also think Savage is once again building these old drilling guns?)
