I have shot a lot of 200 SWC's out of my 625-8, and they are very accurate. I handload a Missouri bullet with 4.8grs 231. The gun does get dirty, but cleans easy because it's stainless. I use the RIMZ mfg'd fullmoon clips, very easy to work with.
Here is the downside, depending on what you use the gun for, the SWC's are not easy to reload fast in the fullmoon clips. If you are competing in a timed event which requires reloads, you may want to consider a round nose bullet.
