I have a CZ 527 in 17 Rem and it's a hammer! Then again, I've never had or heard of a CZ that wasn't.
Yes, you can spot your shots through your scope with it. I've found the 20 grain V-Max pretty much covers all the bases for coyotes down to gophers but like panhandle mentioned, the wind gets ahold of it pretty bad. I don't shoot gophers past 200 yards at the absolute most so it works for me well.
I shoot only moly so the horror stories of fouling and such haven't bitten me yet but they do need cleaning more often than most, moly or no.
I love mine! You need one.
