Thanks for all the replies everyone. I've used their 357 bullets, but not any others and I was hesitant about the larger diameter on them out of my 629-3. My 629 is very accurate with regular .4295-.430 diameter jacketed bullets as well as .430 diameter lead bullets. I ended up ordering me some 240 grain RNFP coated bullets from MBC instead, as I didn't need to buy 1000 this time and the fact that I was ordering a bunch of 357 and 9MM bullets at the same time (saving on shipping costs).

One I wish I could talk Sierra into producing commercially are the 165 grain JHP bullets they make for Cor Bon. I had bought some production overrun stock of these from Midway back in 2013 and they are so much fun to shoot. You can load them hot and they still don't beat you up too badly.
