Well I love mine. I shoot it from a bench and unless you shoot to 100 yards it's not even a challenge. Works like a charm but I have not tried the Aguila 20 g in it. It shoots the CCI standard velocity very well. I don't know if it shoots any better than any other savage bull barrel 22lr but I like it. Only comment is that the stock does not have a swivel point at the front so people mounting bi-pods have to do a bit of work (see other recent post on this page) I shoot it off a bench rest and it's fine.
