I've blasted factory ball ammo and after a while of breathing the smoke I get a severe headache and sinus problems. On my last outing I didn't keep complete track of my different batches but it SEEMS like h335 is the worst but AA2230 and h322 are better.

I'm not looking for stellar accuracy or velocity out of my .223 55gr or .308 147gr blasting loads.

What are the better powders for less smoke and odor?
