Good choice. I love these 8 shooters, and am very happy with mine. The Pro-series is the best of the breed. Dillon precision sells good 8 round clips for these, in 10 packs for $19.95. Also they sell a very functional moon clip loader, "The Deluxe Mooncliptool", that is a small marvel of machinery. This thing takes the pain out of trying to load 8 rounds into the clips. It also has a well designed hole at the end that works well to remove the rounds from the clips. (Sounds like a sales pitch doesn't it.) I was told they're made by a local machinist, who underestimated the demand. I had to wait for mine, but it was worth it. The 357 clips are harder to load than the 45 ACPs, at least for me. Good luck with your 627, it should provide good service.
