LegalWolf,
most people practice with 230 grn FMJ.
If cheap practice ammo is what you want,
Sellier and Bellot is a good brand. Other brands I like are Fiochi, Winchester white box, Federal American Eagle, and Remington UMC. I have not shot Speer lawman, but it is considered to be a quality product.
As far as "clean", do you mean corrosive or nontoxic ? Remington and Winchester produce a brand of ammunition that doesn't have as many harmful pollutants. Check out there websites for more info. In regards to corrosive, I haven't noticed much difference between the various brands . I did have a bad experience with CCI Blazer (lots of copper shavings in the gun and poor accuracy), and others have mentioned PMC as a brand to stay away from too.
Do a search on this forum under "ammunition", you will find many postings about ordering online, price deals ect. Check out
www.ammoman.com for starters.
P.S. I find Fiochi to be the most reliable and accurate out of my Kimber, granted I don't have much experience with various ammo brands. Find what works for you and stick with it
