Wondering if this is normal or if I should get a different brand of charcoal.

I use a Weber grill w/ "HEB brand hardwood mix" and a chimney starter. I used to use lighter fluid & stack the charcoal, but I recently switched to the chimney starter, and that's when the sparks started flying....literally. Any thoughts/ideas why it pops so much?
