I keep thinking about an fac crown in .177 but I haven’t any experience of .177 fac. I’d be interested in trying one, but it could be an expensive mistake? I know people say that they just drill tiny holes things, but have they actually used one, or is it just assumption? I suppose I could easily convert it to .25, but that’s another expense and I don’t really need an fac .25 because I’ve got three rimfires. What’s your views on the .177 fac ?
