I like the idea of not breathing (as much) lead, esp. at the indoor range. I'll think I even may carry with these. These are jacketed flat nose, but don't appear to be fully jacketed - the flat nose is just bare lead, which makes me think these will expand better than ball but feed almost as well - good enough for carry if placement is good. I understand the flash holes are much bigger, because the non-lead primer doesn't flash as much. Question: has this ammo been tested/proven as completely reliable?
