I would like one so only speaking from the outside. If you reload then it probably isn't worth it. Just go to a 17 hornet.
If you don't want to feck around reloading then they could be worth a go. Big issue is rifles. There aren't that many around but you do see the odd Ruger-they are pricey.
A nice forum member let me have a shot out of his B mag at the range one day. he is very happy with it.
Big one is the stupid plastic stocks on them. really need one with the boyds laminate.
Another one to think of on the cheap is a break open H+R/New England 17hmr and get it reamed out. Also have to modify the extractor to fit and possibly the spring so potentially a bit of fecking around.
the Rugers also apparently don't always shoot much better than a B mag so can be hard to justify paying quite a bit extra coin for them
