The math isn't bad, savings of about $30 per thousand bullets from SNScasting.com and other places. The coating stays on the bullet even when you hammer the bullet flat and has been tested many times in suppressors, not leading them up at all. However, my preferred pistol powder (Titegroup) might smoke with them so I'm loading up some test rounds now.
The case for coated bullets looks compelling when shooting.300Blk subsonics compared to conventional bullets. I will be ordering some and will report back.
