I absolutely love the BB's. They are fantastic; the weight is perfect for my guns. They will defiantly improve accuracy part due to the weight, but the dry lubricant as well. I have never had a problem with these BB's and I don't think I ever will. They are high polished seamless BB's perfectly balanced with a solid core. When they hit you target they don't make a chalky mark as shown on the container art and some pictures. They actually make a more pastel like mark some times being some what hard to see. I would recommend maybe getting the orange color instead because it will show up on nearly any background; because with the white ones all the people have to do is wear a white shirt or light gray shirt. The only disadvantage to getting the orange BB's is that they will defiantly be harder to see as they fly through the air. No need to worry about getting the mark off of your clothes becuase the marks are easy to wash off. I would defiantly recommend these BB's over every other BB, but with the cost of price. I have seen these BB's out there at around $17.95 but here this is a much nicer price.

Chalk can possibly mess up your gun, but as long as I have used them, there has been no problem with that what so ever.
White leaves a light gray pastel mark on clothing, so people could easily be able to hide their hit marks with a light gray or white shirt.
